PLANNING COASTAL AREAS FOR TSUNAMI

ABSTRACT Coastal areas are biologically rich and aesthetically pleasing. It contains the large majority of world’s population, possesses some of the highest grade agricultural land, accounts for the lion’s share of tourist trade, and it is the growth pole of expanding economic activity. India has a coastline of about 7,500 kms. of which the mainland accounts for 5,400.Nearly 250 million people live within a distance of 50 kms from the coast. Hence there is a great demand for the use of the coastal land. Especially the fishing community owing to the nature of their work had depended on the coast for livelihood and most of the fishing settlements are very near to the coast.

The recent Tsunami has made us to understand that the planning of coastal areas involves more care than the normal land use planning since our coast is vulnerable to natural disasters. This Review is above all a practical document. However, it is not a manual. Its Emphasis is on the process of planning and implementing risk reduction initiatives along the coastal belt. It focuses on key issues and decision points and how to address them. It has been difficult to present a balanced coverage of such a broad and diverse subject, and there are inevitable gaps and this being a new phenomenon to our Indian coast studies done to our conditions is very limited. Nevertheless, the book is literature evidence-based. The descriptions and discussions are supported by case studies, which aim to give a sense of the range and diversity of practical approaches that can be used.

Disasters triggered by natural hazards are a major threat to life and to sustainable development, especially in developing countries. The human and economic cost of disasters is rising, mainly because societies are becoming more vulnerable to hazards. Socio-economic vulnerability is complex and often deep-rooted. The weaker groups in society suffer most from disasters. Many persistent myths about disasters should be discarded. Disaster reduction strategies are important to address future disasters.

The key factors to reduce potential losses due to tsunami are AWARENESS and PREPAREDNESS. The practical applications of this tsunami risk assessment, in both quantitative and qualitative terms, for implementation into mitigation strategies.

In the context of CRZ provisions, during the present episode of tsunami in the Indian coast the maximum damage has occurred in low lying areas near the coast and High causalities are found in most thickly populated areas , mangroves, forests, sand dunes and coastal cliffs provided the best natural barriers against the tsunami. Validation of the CRZ after the recent Tsunami is to be viewed seriously.

Today, nations around the Indian Ocean are trying to decide whether to allow rebuilding on the coast, which structures to rebuild and which ones to relocate, and how to rebuild to minimize losses in future tsunamis. There are a wide range of technical and management options for coastal protection, which include the sea wall construction and off shore breakers as artificial barriers. Sea walls should be viewed as an option in areas which are well developed, densely populated, low lying and very near the coast.(density of coastal area of kerala is 2147 per sq.km., in pondicherry settlement starts 20-30 mts from the coast North Chennai high density and absence of lengthier coast ) . Critical infrastructure facilities which require foreshore can be guarded with sea walls. Sea wall could never be an option for the entire coast.

Places that had healthy coral reefs and intact mangroves, which act as natural buffers, were less badly hit by the tsunami than those where the reefs had been damaged and mangroves ripped out and replaced by prawn farms and poorly planned beachfront hotels. Mangroves and vegetative cover had considerably reduced the impact of tsunami on the coast. With the importance of CRZ felt after this tsunami the vegetative cover and CRZ can be utilized together to create tsunami forest to act as buffer. These tsunami forest should be handed over to the local communities. The rebuilding of the forest could be phased in stages.

Connectivity played an important role during the recent Tsunami. The settlements with better connectivity suffered less loss. Better connectivity in terms of roads facilitated immediate relief measures.

Avoiding or minimizing the exposure of people and property through land use planning can mitigate tsunami risk most effectively. Development should be prevented in high-hazard areas wherever possible. Where development cannot be prevented, land use intensity, building value, and occupancy should be kept to a minimum. In areas where it is not feasible to restrict land to open-space uses, other land use planning measures can be used. These include strategically controlling the type of development and uses allowed in hazard areas, and avoiding high-value and highoccupancy uses to the greatest degree possible. Land use policies and programs should address tsunami hazards as part of a comprehensive tsunami mitigation program. Such an update should focus on the location and vulnerability to damage of existing and planned land uses.

GLOSSARY ACCEPTABLE RISK :The level of loss a society or community considers acceptable given existing social, economic, political, cultural, technical and environmental conditions. In engineering terms, acceptable risk is also used to assess structural and nonstructural measures undertaken to reduce possible damage at a level, which does not harm people, and property, according to codes or "accepted practice" based, among other issues, on a known probability of hazard.

ASSURANCE INDICATORS : Generic characteristics of ERM that allow the emergency risk manager to qualitatively assess their degree-of-readiness for catastrophic events.

BUILDING CODES :Ordinances and regulations controlling the design, construction, materials, alteration and occupancy of any structure to insure human safety and welfare. Building codes include both technical and functional standards.

CAPACITY :A combination of all the strengths and resources available within a community, society or organization that can reduce the level of risk, or the effects of a disaster. Capacity may include physical, institutional, social or economic means as well as skilled personal or collective attributes such as leadership and management. Capacity may also be described as capability.

CAPACITY BUILDING :Efforts aimed to develop human skills or societal infrastructures within a community or organization needed to reduce the level of risk. In extended understanding, capacity building also includes development of institutional, financial, political and other resources, such as technology at different levels and sectors of the society.

CLIMATE CHANGE :The climate of a place or region is changed if over an extended period (typically decades or longer) there is a statistically significant change in measurements of either the mean state or variability of the climate for that place or region. Changes in climate may be due to natural processes or to persistent anthropogenic changes in atmosphere or in land use. Note that the definition of climate change used in the

- 16 -

PLANNING COASTAL AREAS FOR TSUNAMI

United Nations Framework Convention on Climate Change is more restricted, as it includes only those changes which are attributable directly or indirectly to human activity.

COPING CAPACITY :The means by which people or organizations use available resources and abilities to face adverse consequences that could lead to a disaster. In general, this involves managing resources, both in normal times as well as during crises or adverse conditions. The strengthening of coping capacities usually builds resilience to withstand the effects of natural and human-induced hazards.

CO-ORDINATION :The bringing together of organizations and resources to ensure effective disaster management.

COMMUNITY :A group of people with a commonality of association, generally defined by location, shared experience, or function.

CRITICAL INFRASTRUCTURE :A service, facility or a group of services or facilities, the loss of which will have severe adverse effects on the physical, social, economic or environmental well being or safety of the community.

CONSEQUENCE :The outcome of a situation or event expressed qualitatively or quantitatively, being a loss, injury, disadvantage or gain. In the ERM context, consequences are generally described as the effects on persons, stakeholders, communities, the economy and the environment.

DISASTER :A serious disruption of the functioning of a community or a society causing widespread human, material, economic or environmental losses which exceed the ability of the affected community or society to cope using its own resources. A disaster is a function of the risk process. It results from the combination of hazards, conditions of vulnerability and insufficient capacity or measures to reduce the potential negative consequences of risk.

DISASTER RISK MANAGEMENT :The systematic management of administrative decisions, organization, operational skills and abilities to implement policies, strategies and coping

- 17 -

PLANNING COASTAL AREAS FOR TSUNAMI

capacities of the society or individuals to lessen the impacts of natural and related environmental and technological hazards.

DISASTER RISK REDUCTION :The systematic development and application of policies, strategies and practices to minimize vulnerabilities, hazards and the unfolding of disaster impacts throughout a society, in the broad context of sustainable development.

EARLY WARNING :The provision of timely and effective information, through identified institutions, that allows individuals exposed to a hazard to take action to avoid or reduce their risk and prepare for effective response.

EMERGENCY :An event, actual or imminent, which endangers or threatens to endanger life, property or the environment, and which requires a significant and coordinated response. In the ERM context for critical infrastructure, an event that extends an organization beyond routine processes.

ENVIRONMENT :Conditions or influences comprising built, physical and social elements, which surround or interact with stakeholders and communities.

ERM - EMERGENCY RISK MANAGEMENT :A systematic process that produces a range of risk treatments that reduce the likelihood or consequences of events.

ESSENTIAL SERVICE :An indispensable supply or activity. The various Australian jurisdictions have various legislative instruments in place to either define or constitute essential services, their roles and responsibilities. These should be properly researched and understood as part of ERM.

EXTERNALITY :Influences exerted by others or the environment, either real or perceived, on an organizations ability to operate.

FORECAST :Definite statement or statistical estimate of the occurrence of a future event (UNESCO, WMO). This term is used with different meanings in different disciplines.

PLANNING COASTAL AREAS FOR TSUNAMI

GEOLOGICAL HAZARD :Natural earth processes or phenomena that may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation. Geological hazard includes internal earth processes or tectonic origin, such as earthquakes, geological fault activity, tsunamis, volcanic activity and emissions as well as external processes such as mass movements: landslides, rockslides, rock falls or avalanches, surfaces collapses, expansive soils and debris or mud flows. Geological hazards can be single, sequential or combined in their origin and effects. GEOGRAPHIC INFORMATION SYSTEM (GIS) :A computerized database for the capture, storage, analysis and display of locationally defined information. Commonly, a GIS portrays a map on which this information is overlaid.

GLOBAL POSITIONING SYSTEM (GPS) : GPS is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. The satellites are reference points to calculate positions accurate to a matter of meters. By using advanced forms of GPS, measurements are better than a centimeter. In effect, each square meter on the planet has a unique address.

HAZARD :A potentially damaging physical event, phenomenon or human activity that may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation. Hazards can include latent conditions that may represent future threats and can have different origins: natural (geological, hydro meteorological and biological) or induced by human processes (environmental degradation and technological hazards). Hazards can be single, sequential or combined in their origin and effects. Each hazard is characterized by its location, intensity, frequency and probability.

HAZARD ASSESSMENT OR HAZARD VULNERABILITY ANALYSIS :The process of estimating, for defined areas, the probabilities of the occurrence of potentially-damaging phenomenon of given magnitudes within a specified period of time. A systematic approach used to analyze the effectiveness of the overall (current or proposed) security and safety systems at a particular facility. Hazard assessment involves analysis of formal and informal historical records, and skilled interpretation of existing topographical graphical, geological geomorphologic, hydrological, and land-use maps. The analysis first determines the objectives of the facility’s physical protection system. Next, it identifies the physical protection

- 19 -

elements in place (or proposed) to prevent or mitigate security concerns. Finally, it analyzes the system design against the objectives in a systematic, quantitative manner in order to determine if the physical protection system is effective and acceptable for that facility. Similar Terms Vulnerability Analysis, Risk Assessment, Threat Assessment.

HAZARD MITIGATION :The process of alleviating hazards or reducing the risk of hazards by the use of proactive measures. (FEMA’s Disaster Mitigation Act) Any sustained action taken to reduce or eliminate the long-term risk to human life and property from hazards.

HUMAN VULNERABILITY : A human condition or process resulting from physical, social, economic and environmental factors, which determine the likelihood and scale of damage from the impact of a given hazard.

INTERDEPENDENCY :The essential external organizational, systems or technical connectivity associated with critical infrastructure operations

LAND-USE PLANNING :Branch of physical and socio-economic planning that determines the means and assesses the values or limitations of various options in which land is to be utilized, with the corresponding effects on different segments of the population or interests of a community taken into account in resulting decisions. Land-use planning involves studies and mapping, analysis of environmental and hazard data, formulation of alternative land-use decisions and design of a long-range plan for different geographical and administrative scales. Land-use planning can help to mitigate disasters and reduce risks by discouraging high-density settlements and construction of key installations in hazard-prone areas, control of population density and expansion, and in the sitting of service routes for transport, power, water, sewage and other critical facilities.

LATENT RISK :A risk that is present but not yet apparent.

LIKELIHOOD :Used as a qualitative description of probability and frequency.

MITIGATION :Acts or efforts to lesson the consequences of an event. These may be carried out before, during or after an event.

NATURAL DISASTER :A serious disruption triggered by a natural hazard causing human, material, economic or environmental losses, which exceed the ability of those affected to cope.

NATURAL DISASTER, SLOW ONSET :A disaster event that unfolds alongside and within development processes. The hazard can be felt as an ongoing stress for many days, months or even years. Drought is a prime example.

NATURAL DISASTER, RAPID ONSET : A disaster that is triggered by an instantaneous shock. The impact of this disaster may unfold over the medium- or long-term. An earthquake is a prime example.

PHYSICAL RESOURCE :The process of engaging stakeholders and communities by analyzing and documenting courses of action and testing them for efficiency and effectiveness.

PREPAREDNESS :Measures to ensure that communities and organizations are capable of coping with the effects of emergencies.

PREVENTION :Measures to eliminate or reduce the likelihood or consequences of an event. This also includes reducing the severity or intensity of an event so it does not become an emergency.

RESPONSE :Measures taken in anticipation of, during and immediately after, emergencies to ensure the adverse consequences are minimized.

RETROFITTING (OR UPGRADING) :Reinforcement of structures to become more resistant and resilient to the forces of natural hazards. Retrofitting involves consideration of changes in the mass, stiffness, damping, load path and ductility of materials, as well as radical changes such as the introduction of energy absorbing dampers and base isolation systems. Examples of retrofitting includes the consideration of wind loading to strengthen and minimize the wind force, or in earthquake prone areas, the strengthening of structures.

Chapter 1 INTRODUCTION 1.1

CONTEXT A large tsunami triggered due to an earthquake Offshore Sumatra at 7:58:53 AM local time on 26 December 2004 created havoc in several countries

of

Indonesia,

the

Indian

Thailand,

Ocean,

Malaysia,

primarily Andaman–

Nicobar (India), East Coast of India, Sri Lanka, Somalia, Madagascar and several small islands in this area. It caused maximum loss in terms of affected

area,

leaving

millions

of

people

homeless. More than 200,000 human lives are reported to have been lost and millions have been injured; thousands are reported missing. It has affected the citizens of more than 50 countries including tourists from developed countries. The loss of property is so large that even UN officials hesitate to make an estimate and suggest that it may take decades to normalize the situation in the affected regions .

India has a coastline of about 7,500 km.of which the mainland accounts for 5,400.Nearly 250 million people live within a distance of 50 kms from the coast. The coastal zone is also endowed with a very wide range of coastal ecosystems like mangroves, coral reefs, sea grasses, salt marshes, sand dunes, estuaries, lagoons, etc., which are characterized by distinct biotic and a biotic processes. The coastal areas are assuming greater importance in recent years, owing to increasing human population, urbanization and accelerated developmental activities . The recent Tsunami has posed a great challenge among the planners in refurbishing the coastal community.

1.2 NEED FOR THE STUDY:

“While it is agreed that no human interference is possible to control such an event but Precautionary measures such as coastal area planning for locating coastal communities in safer areas, protecting and propagating the natural protecting systems such as mangroves, coral reefs, shelter belt plantations, along with installation of early warning systems, timely evacuation and relief measures can minimize loss of life and property to a large extent”

1

and the quote from Prime Minister Dr. Manmohan Singh,

Opportunity for strengthening socially and scientifically, our capacity for safeguarding human and ecological security in coastal areas. It also provides an opportunity for enhancing the economic well being of the fisher and farm families along the shoreline through an integrated bio-shield-cum- bio-village programme. The recent Tsunami has made us to understand that the planning of coastal areas involves more care than the normal land use planning since our coast is vulnerable to natural disasters.

1.3 SCOPE AND LIMITATIONS

This Review is above all a practical document. However, it is not a manual. Its Emphasis is on the process of planning and implementing risk reduction initiatives along the coastal belt. It focuses on key issues and decision points and how to address them. It has been difficult to present a balanced coverage of such a broad and diverse subject, and there are inevitable gaps and this being a new phenomenon to our Indian coast studies done to our conditions is very limited. Nevertheless, the book is literature evidence-based. The descriptions and discussions are supported by case studies, which aim to give a sense of the range and diversity of practical approaches that can be used.

Chapter 2 NATURAL HAZARDS AND DEVELOPMENT 2.1 WHAT IS A NATURAL HAZARD?

A potentially damaging physical event, phenomenon or human activity that may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation. Hazards can include latent conditions that may represent future threats and can have different origins: natural (geological, hydro meteorological and biological) or induced by human processes (environmental degradation and technological hazards). Hazards can be single, sequential or combined in their origin and effects. Each hazard is characterized by its location, intensity, frequency and probability.

2.2 DIFFERENCE BETWEEN A HAZARD AND A DISASTER “Strictly speaking, there is no such thing as a natural disaster, but there are natural hazards, such as cyclones and earthquakes. The difference between a hazard and a disaster is an important one. A disaster takes place when a community is affected by a hazard (usually defined as an event that overwhelms that community’s capacity to cope). In other words, the impact of the disaster is determined by the extent of a community’s vulnerability to the hazard. This vulnerability is not natural. It is the human dimension of disasters, the result of the whole range of economic, social, cultural, institutional, political and even psychological factors that shape people’s lives and create the environment that they live in.”

2.3 CHARACTERISTICS OF DISASTER Some or all of the following characterizes disasters: ¾ They are disruptive to individuals and communities; ¾ They are not part of day-to-day experience and are outside normal life expectations; ¾ They are unpredictable in occurrence and effects; ¾ They require a response for which normal local resources may be inadequate;

- 34 -

¾ They have a wide range of effects and impacts on the human and physical environment;

¾ There are complex needs in dealing with them; Relation Between Risk, Vulnerability And Disaster

R = H • Pop • Vul Where R is the risk (number of killed people. H is the hazard, which depends on the frequency and strength of a given hazard Pop is the population living in a given exposed area Vul is the vulnerability and depends on the socio-political- economical context of this population

Since the return period of destructive Tsunami are very large , Tsunami mitigation measure should be considered along with mitigation measure of other natural hazards like tropical cyclone, coastal flooding, coastal erosion (due strong monsoon and other natural hazards) etc. However, specific Tsunami protective measures may be undertaken for the vital coastal installations like important ports, nuclear plants along the coast high value coastal installation properties

- 37 -

PLANNING COASTAL AREAS FOR TSUNAMI

PREPAREDNESS

Specific measures taken before disasters strike, usually to forecast or warn against them, take precautions when they threaten and arrange for the appropriate response (such as organizing evacuation and stockpiling food supplies). Preparedness falls within the broader field of mitigation.

PREVENTION

Activities to ensure that the adverse impact of hazards and related disasters is avoided. As this is unrealistic in most cases, the term is not widely used nowadays.

RECOVERY

Measures supporting individuals, communities and organizations in the reconstruction or restoration of critical infrastructure, emotional, economic and physical well being.

Bringing disaster risk reduction and development concerns closer together requires three steps: •

The collection of basic data on disaster risk and the development of planning tools to track the changing relationship between development policy and disaster risk levels.

•

The collation and dissemination of best practice in development planning and policy that reduce disaster risk.

•

The galvanizing of political will to reorient both the development and disaster management sectors.

2.6 DISASTER MYTHS Myths about disasters are widespread and persistent, despite repeated experience to the contrary and the findings of social science research. They are often reinforced in the public mind by media coverage. Disaster myths are a significant problem, because they influence the way operational agencies think and act. Among the most prominent myths are the following: • Disasters are acts of God (which means that nothing can be done about them) or acts of nature (which means that the problem can be resolved by scientific or technical interventions alone). • People are fatalistic about disasters and do not take action to protect themselves against future events. • When a disaster strikes, people are helpless, passive, dependent victims incapable of carrying out even basic tasks. Therefore they rely on help from aid agencies. • People panic during disasters; they cannot be relied upon to react rationally at times of great danger. • The chaos that follows disasters encourages many people to engage in anti-social behaviors (particularly looting). • External ‘experts’, with their advanced knowledge and technologies, are the main agents in risk reduction and disaster response. • The situation will return to normal within a few months of the disaster, and support for rehabilitation need only be for the short term.

2.7 CONCLUSIONS • Disasters triggered by natural hazards are a major threat to life and to sustainable development, especially in developing countries. • The human and economic cost of disasters is rising, mainly because societies are becoming more vulnerable to hazards. • Socio-economic vulnerability is complex and often deep-rooted. • The weaker groups in society suffer most from disasters. • Many persistent myths about disasters should be discarded.

• Disaster reduction strategies are important to address future disasters.

Chapter 3 TSUNAMI CHARACTERISTICS 3.1 WHAT IS A TSUNAMI?

•

A tsunami is a series of waves with a long wavelength and period (time between crests). Time

between crests of the wave can vary from a few minutes to over an

hour. •

Tsunamis are often incorrectly called tidal waves; they have no relation to the daily ocean tides.

•

Tsunami (soo-NAH-mee) is a Japanese word meaning harbor wave.

•

Tsunamis can occur at any time of day or night.

3.2 HOW ARE TSUNAMIS GENERATED?

•

Tsunamis are generated by any large, impulsive displacement of the seabed level.

•

Earthquakes generate tsunamis by vertical movement of the sea floor. If the sea floor movement is horizontal, a tsunami is not generated. Earthquakes of M > 6.5 are critical for tsunami generation.

•

Tsunamis are also triggered by landslides into or under the water surface, and can be generated by volcanic activity and meteorite impacts.

•

PLANNING COASTAL AREAS FOR TSUNAMI

3.3 HOW OFTEN DO TSUNAMIS OCCUR? •

On the average, there are two tsunamis per year somewhere in the world, which cause damage near the source.

•

Approximately every 15 years a destructive, Pacific-wide tsunami occurs.

•

The destructive tsunami on Dec 26th, 2004 on the Indian Coast seems to have occurred for the first time in the history.

3.4 HOW FAST DOES A TSUNAMI TRAVEL?

•

Tsunami velocity is dependent on the depth of water through which it travels (Velocity equals the square root of water depth h times the gravitational acceleration g, V =√g h).

•

Tsunamis travel approximately 700 kmph in 4000 m depth of seawater. In 10 m of water depth the velocity drops to about 36 kmph.

•

For example, the tsunami from Sumatra coastal earthquake traveled to Tamil Nadu coast in about two hours.

•

Even on shore tsunamis can faster than a person can run.

FIGURE 3.4 TSUANMI AFFECTED AREAS ON THE INDIAN COAST SOURCE : US AID

3.5 HOW BIG IS A TSUNAMI? •

Tsunamis range in size from centimeters to over 30 m height. Most tsunamis are less than 3 m in height.

•

In deep water (greater than 200 m), tsunamis are rarely over 1m high and will not be noticed by ships due to their long period (time between crests).

•

As tsunamis propagate into shallow water, the wave height can increase by over 10 times.

•

Tsunami heights can vary greatly along a coast. The waves are amplified by certain shoreline and bathymetric (sea floor) features.

•

A large tsunami can flood land up to more than 1.5 km from the coast.

•

The force of some tsunamis is enormous. Large rocks weighing several tons along with boats and other debris can be moved inland hundreds of feet by tsunami wave activity. Homes and other buildings are destroyed. All this material and water move with great force and can kill or injure people.

3.6 WHAT DOES A TSUNAMI LOOK LIKE WHEN IT REACHES SHORE? •

Normally, a tsunami appears as a rapidly advancing or receding tide.

•

It some cases a bore (wall of water) or series of breaking waves may form.

•

Some times a tsunami causes the water near the shore to recede, exposing the ocean floor, then the wave crest comes with a high speed.

•

Tsunamis can travel up rivers and streams that lead to the sea.

3.7 HOW IS A TSUNAMI DIFFERENT FROM A WIND-GENERATED WAVE? •

Wind-generated waves usually have periods (time between crests) of 5 to 20 seconds. Tsunami periods are usually between 5 minutes and an hour.

•

Wind-generated waves break as they shoal and lose energy offshore. Tsunamis act more like a flooding wave. A 6 m tsunami is a 6 m rise in sea level.

Chapter 4 TSUNAMI RISK IN INDIA AND ITS ASSESSMENT 4.1 SOME HISTORICAL TSUNAMIS Prior to the Tsunami of 26 December 2004, the most destructive Pacific-wide Tsunami of recent history was generated along the coast of Chile on May 22, 1960. No accurate assessment of the damage and deaths attributable to this Tsunami along the coast of Chile can be given; however, all coastal towns between the 36th and 44th (latitude) parallels either were destroyed or heavily damaged by the action of the waves and the quake.

The combined Tsunami and earthquake toll included 2,000 killed, 3000 injured

2,000,000 homeless and $550 million damages. Off Corral, the waves were estimated to be 20.4 meters (67 feet) high. The Tsunami caused 61 deaths in Hawaii, 20 in the Philippines, and 100 or more in Japan. Estimated damages were $50 million in Japan, $24 million Hawaii and several millions along the west coast of the United States and Canada. Wave heights varied from slight oscillations in some areas to range of 12.2 meters (40 feet) at Pitcairn Islands; 10.7 meters (35 feet) at Hilo, Hawaii and 6.1 meters (20 feet) at various places in Japan.

The hydrographic survey in Japan after the great Kwato earthquake of September 1, 1923 showed that vertical displacements of the order of 100 meters had occurred over a large area of sea floor.

Tsunamis are very common over the Pacific Ocean because it is

surrounded on all sides by a seismically active belt.

In the Hawain Islands, Tsunamis

approach from all directions, namely, from Japan, the Aleutian Islands and from South America.

4.2 TSUNAMIS IN INDIA

The Indian coastal belt has not recorded many Tsunamis in the past. Waves accompanying earthquake activity have been reported over the North Bay of Bengal. During an earthquake in 1881 which had its epicenter near the centre of the Bay of Bengal, Tsunamis were reported.

The earthquake of 1941 in Bay of Bengal caused some damage in Andaman

- 45 -

PLANNING COASTAL AREAS FOR TSUNAMI

region. This was unusual because most Tsunamis are generated by shocks which occur at or near the flanks of continental slopes. During the earthquakes of 1819 and 1845 near the Rann of Kutch, there were rapid movements of water into the sea. There is no mention of waves resulting from these earthquakes along the coast adjacent to the Arabian sea, and it is unlikely that Tsunamis were generated. Further west, in the Persian Gulf, the 1945 Mekran earthquake (magnitude 8.1) generated Tsunami of 12 to 15 metres height. This caused a huge deluge, with considerable loss of life and property at Ormara and Pasi. The estimated height of Tsunami at Gulf of Combay was 15m but no report of damage is available. The estimated height of waves was about 2 metres at Mumbai, where boats were taken away from their moorings and casualties occurred. A list showing the Tsunami that affected Indian coast in the past is given in Table-4.2. The information given in the Table is sketchy and authenticity cannot be confirmed except the Tsunami of 26th December 2004.

Above facts indicate the coastal region of Gujarat is vulnerable to Tsunamis from great earthquakes in Mekran coast.

Earthquake of magnitude 7 or more may be dangerous.

It

may be noted that all earthquake do not generate Tsunami. Research is still being undertaken in this field.

For the Indian region, two potential sources have been identified,

namely Mekran coast and Andaman to Sumatra region.

4.3 EXPOSURE TO TSUNAMIS

Coastlines have always been a favored location for human settlements. Because of the attractiveness of coastal locations and the long gaps between devastating tsunami events, coastal communities have continued to develop in recent times with new housing, maritime facilities, and resort developments. As a result, the destructive force of tsunamis threatens more people and facilities.

4.4 TSUNAMI RISK It will be assessed by a deterministic approach according to the following:

TSUNAMI RISK = TSUNAMI HAZARD . EXPOSURE . VULNERABILITY.

(a)

For the Tsunami Hazard assessment: •

Preparation of data-base of historical and archival information (newspapers, archives, anecdotal information, literature survey) of relevant Indian Tsunamis, with the emphasis clearly on the December 26, 2004 event.

•

Analyses of these data, to -define the scenario Tsunamis from various earthquake sources -prepare the Tsunami hazard map.

(b)

For the Exposure •

List all habitations below 15 m contour level and locate on a map.

•

List and locate all vital installations below 15 m contour level (Ports, Harbors, Schools, Hospitals, Power Plants, Bridges, etc.)

(c)

For the VULNERABILITY assessment: •

Based on the earthquake vulnerability assessment, define the vulnerability of various exposed elements on the coastal, island and reef environments and in the Ports and Harbors

•

(d)

Prepare vulnerability charts and matrices.

For the RISK assessment: •

Integrate these hazard and exposure data with vulnerability assessments to obtain the risk assessment.

4.5 SCENARIO TSUNAMI

PLANNING COASTAL AREAS FOR TSUNAMI

The following parameters will need to be defined: •

Tsunami source region:

•

Mode of generation:

•

Potential wave heights

•

Maximum Run-up (maximum height of the water onshore observed/inferred above the mean sea level. Usually measured at the horizontal inundation limit)

•

Tsunami intensity

I=0.5 log 2H (Pelinovsky, 1996)

with H = average maximum run-up height >3 m.

Imax = 2.5

4.6 TSUNAMI HAZARD MAP The Tsunami hazard map may be empirically defined using a deterministic approach, based upon potential maximum wave heights for the scenario tsunamis.

The

definition of the tsunami hazard zones, as preliminary estimates, is given in Table. For the terrestrial environment the hazard may be presented as inundation levels, in terms of run-up heights at specified land contours. For the marine environment (“ON WATER”) Harbour, Bay and Reefs – hazard may be given in terms of potential maximum wave heights. CHARACTERISTIC

DEFINITION

PLANNING COASTAL AREAS FOR TSUNAMI

4.7 TSUNAMI VULNERABILITY ASSESSMENT The exposure inventory with vulnerability to tsunami impact for both the built and natural environments will need to be developed for shores and Harbours. Potential damage is related to the hydrological controls of wave action (surging), flooding and debris deposition, and consequent geotechnical controls to damage by liquefaction, cracking and slumping.

These result in structural damage to buildings, water

damage to contents, flooding damage to infrastructure (roads, bridges, water supply, sewerage, wharves, sea-walls), damage to navigational aids and reef damage. There is the potential for “seiching” in the shallow harbour areas where, alternately (from the tsunami waves), water is drained from the harbour and then flooded to depths greater than high tide levels.

This has the potential for threat to human life

(death and injury) from people collecting fish from the harbour seafloor.

In the

Harbour, waves are a threat to shipping (sinking, striking wharves) and fishermen (drowning). The vulnerability assessment is expressed as details of elements of the built, natural and human environments vulnerable to potential tsunami-related damage. These need to be considered in terms of the Tsunami Hazard Zones for the terrestrial environments around the shores and the marine environments.

Tsunami Risk Assessment By integrating the hazard and vulnerability assessments, the tsunami risk assessment is to be developed in terms of zonation and inundation maps and associated affects.

Practical Applications

The key factors to reduce potential losses due to tsunami are AWARENESS and PREPAREDNESS. The practical applications of this tsunami risk assessment, in

4.10 Conclusions Strategies for Applying Hazard Information to Reducing Future Losses

Strategy 1: Incorporate Hazard Information into Short- and Long-Term Planning Processes One of the best ways to prevent future losses from natural hazards is to ensure the subject is ad-dressed along with all other issues in short- and long-term comprehensive planning programs and project reviews.

Strategy2: Use Hazard Information to Build Public and Political Support for Mitigation Measures Hazard information, loss estimates, and planning scenarios are powerful tools to create understanding and commitment to mitigation.

Strategy 3: Estimate Reduced Future Losses by Evaluating the Effectiveness of Loss-Prevention Measures One of the biggest challenges in preventing losses from rare events such as tsunamis is to show that mitigation measures would be effective. At the community level, the value of mitigation investments can be estimated by using scenarios and maps to evaluate actions taken to reduce vulnerability and exposure to tsunami hazards.

Strategy 4: Periodically Re-evaluate Community Vulnerability and Exposure The tsunami hazard is unlikely to change over time, but communities are changing constantly. This dynamic process leads to changes in vulnerability and exposure.

5.3 CONCLUSIONS

In the context of CRZ provisions, during the present episode of tsunami in the Indian coast, the following preliminary observations are made:

a) The maximum damage has occurred in low lying areas near the coast.

b) High causalities are found in most thickly populated areas.

c) The mangroves, forests, sand dunes and coastal cliffs provided the best natural barriers against the tsunami.

d) Heavy damage is reported in areas where sand dunes were heavily mined (eg. Nagapatinam & Kolachal) and where coastal vegetation was less.

Clauses of the CRZ Notification Para 6(2) CRZ –I, II, III

No specific mention in the Notification. Para 6(2) CRZ –I No new construction is permitted. Para 3(1) of the notification states that clearance shall be given for any activity within the Coastal Regulation Zone only if it requires waterfront and foreshore facilities. No specific mention in the notification. Para 6(2) CRZ –I No new construction is permitted. Para 3(1) of the notification states that clearance shall given for any activity within the Coastal Regulation Zone only if it requires waterfront and foreshore facilities. No specific mention in the notification. Para 6(2) CRZ –I No new construction is permitted. Para 3(1) of the notification states that clearance shall be given for any activity within the Coastal Regulation Zone only if it requires waterfront and foreshore facilities.

Interpretation / Comments A lawyer in the Madras High Court, Mr. T.Mohan states ‘there is a difference in the interpretation of the words ‘no construction’, ‘no new construction’ and ‘no reconstruction’. The term ‘new construction’ need not apply to the reconstruction of an earlier authorised structure that was demolished or destroyed by the tsunami, if it is being reconstructed (as part of rehabilitation measures) provided the reconstructed structure is as per the same specifications, style and design as the earlier construction. There should be no increase in the area occupied or in the height of the construction as earlier’. However it is not really clear if such reconstruction is permitted within the CRZ – I, though the notification does not explicitly prohibit it. Applying the above interpretation, reconstruction of structures that were demolished in the CRZ –I areas The Notification does not explicitly state its position on temporary shelters. There is no specific mention of cyclone shelters/tsunami shelters in CRZ It would seem logical that cyclone relief shelters would have to be located in areas close to existing settlements and work area.

Fishing related constructions that could be considered permissible only if the activity requires foreshore or waterfront facilities. For e.g fish washing and sun drying on the beach requires the foreshore and waterfront and is not prohibited in the notification. There are several fishing related activities that do not require the waterfront or foreshore area like the storage or desiccation of fish products in permanent constructions does not require the foreshore or waterfront and even today takes place at distances beyond 500 m. Constructions of the latter category cannot be permitted in the CRZ. No new constructions would be permitted in CRZ –I areas. For the reconstruction of destroyed sheds in the CRZ –I areas,a clarification from the MoEF and Tamil Nadu SCZMA will have to the sought. Only those constructions that require the foreshore and waterfront maybe permitted. Sheds could be considered as permissible and requiring the foreshore area, only if they catering to beach landing crafts that cannot be hauled further inland and if these sheds are meant for petty repairs. Large boat making yards would not be permitted in the 500 m area unless these require docks..

Chapter 6 ARTIFICIAL AND NATURAL BARRIERS 6.1 SEA WALL AND OFF SHORE BREAKERS

Today, nations around the Indian Ocean are trying to decide whether to allow rebuilding on the coast, which structures to rebuild and which ones to relocate, and how to rebuild to minimize losses in future tsunamis. There are a wide range of technical and management options for coastal protection, which include the sea wall construction and off shore breakers as artificial barriers.

6.2 ADVANTAGES OF SEA WALL CONSTRUCTION

One town in Thailand that survived almost unscathed had built a sea wall of huge concrete pyramids across their coastline. A new-type seawall constructed in Japan. This seawall has a buffer zone to prevent coastal inundation due to overtopping waves. The waves overtopped the front face of the seawall can permeate a buffer zone installed in front of the original seawall

6.3 DIS-ADVANTAGES OF SEA WALL CONSTRUCTION: "Sea walls are like fortification on the shoreline. They are effective against small waves but not when it comes to a Tsunami,” Sea walls also give a false sense of security and delay swift action. "Bio-shield" or planting vegetation is a better option as it acts as an environment-friendly barrier against the water current. The United Nations Country Programme Team when received requests from State and district governments about the need to build sea defenses along the Tamil Nadu coast they came out saying,

It is clear that the construction of a 600 km long seawall along the Coromandel Coast is an extremely costly measure which could generate more problems than it solves. Among the major disadvantages are the high cost of building these structures, particularly off shore breakwaters and seawalls. Maintaining these structures is expensive. Most of these

- 64 -

PLANNING COASTAL AREAS FOR TSUNAMI

structural coastal defenses also have a high impact on shoreline sediment transport, coastal ecosystems and environmental assets such as scenic beaches. Encroachment of structures on sea access by local communities can also impact livelihoods.

6.4 CONCLUSIONS Sea walls should be viewed as an option in areas which are well developed, densely populated, low lying and very near the coast.(density of coastal area of kerala is 2147 per sq.km., in pondicherry settlement starts 20-30 mts from the coast North Chennai high density and absence of lengthier coast ) . Critical infrastructure facilities which require foreshore can be guarded with sea walls. Sea wall could never be an option for the entire coast. Technological advancement is must for sea wall construction.

6.5 VEGETATION ALONG THE COAST

A coastal landscape is generally comprised of combination of landforms, coastal water surfaces, vegetation and other significant visual elements. Landscape values and the presence of distinctive natural features are among the qualities which go to make up the natural character of particular coastal areas. Distinctive natural features within or immediately adjacent to the coastal marine area can include beaches, sand spits, islands, and reefs.

Mangrove forests reduced the impact of cyclone. If Mangrove ecosystem or Wet lands had found in these areas the impact would have reduced as mangrove ecosystem would have acted as buffer zones People living along the coastal zones must be encouraged to organize afforest ration programme of mangrove for preventing future impact of tsunami in the coastal zones. While there is no guarantee that replanting mangroves will prevent another tsunami tragedy, coastal communities need many more life-saving belts to help filter the energy of strong winds and tidal waves. Until recently, mangrove forests have been recognized mainly for their direct-use values.

6.7 CONCLUSIONS Mangroves and vegetative cover had considerably reduced the impact of tsunami on the coast. With the importance of CRZ felt after this tsunami the vegetative cover and CRZ can be utilized together to create tsunami forest to act as buffer. These tsunami forest should be handed over to the local communities. The

PHASE I [0-2 YEARS] : RECOVERING THE COAST • community projects may include the planting that will provide a vegetative buffer. • Along with the extensive mangrove reforestation, planting of a variety of other coastal species that have been lost, such as Cocos nucifera and Casuarina equisetifolia to be promoted. • Intercrops to be planted and harvested between trees to stabilize and protect the soil. The species selected are saline resistant as the effect of salt intrusion after tsunami would still be present in the soil and ground water. and protect the soil.

Chapter 7 CONNECTIVITY 7.1 ROLE OF CONNECTIVITY DURING RECENT TSUNAMI

During the recent tsunami the devastation wasn’t uniform throughout the coastal area. There were several issues and reasons that determined the devastation. One such reason identified was the connectivity,

PLANNING COASTAL AREAS FOR TSUNAMI

The reason for such kind of irony is CONNECTIVITY Soththikuppam, is almost like an island. The only means of connectivity was by FERRY, that too stops by night. In order to take the road route, one have to travel another 6km via nochchikadu. During the recent tsunami people rushed to the nearest ferry dock in the back waters and were washed away by the wave. In Singarathoppu, though water surrounded them from all sides, people ran up the bridge and guarded themselves,

Thus connectivity holds an important role, not only in saving lives and property, but also in easing the rescue operations and rehabilitation measures.

7.2 CONCLUSIONS

Connectivity played an important role during the recent Tsunami. The settlements with better connectivity suffered less loss. Better connectivity in terms of roads facilitated immediate relief measures. Movement assessment: the movement during Tsunami was mostly away from the sea.That is a horizontal movement perpendicular to the coast.

Chapter 8 EVACUATION PLAN 8.1 ROLE OF EVACUATION PLAN Evacuating people can save lives and reduce injuries, but it will have little, if any, effect on reducing property and economic losses.

In coastal areas where building and population densities are high, where roads, bridges, and other horizontal evacuation methods are limited, or where warning time may be insufficient, vertical evacuation may be needed as an alternative to horizontal evacuation. Vertical evacuation, while dependent on structures for its success, is primarily an emergency preparedness and response measure.

8.2 TYPES OF EVACUATION

vertical evacuation—moving people to higher floors in buildings

horizontal evacuation—moving people to more distant locations or higher ground.

Dense areas require vertical evacuation Best possible routes has to be found and escape route mapping has to be done

8.3 EVACUATION CENTRES Immediate evacuation centers in each settlement within reachable distance, at the same time at a safer distance. These are high raised structures or structures present in a highly elevated land. Existing structures like school or a community hall is identified for the purpose.

CASE STUDY EVACUATION TOWER AND BUILDING Photo shows an evacuation tower in Japan. This tower is 5 stories high and has about 220m 2 in area above the ground floor. It can admit 500 people. It is placed in the area difficult to evacuation by the existence of a river. It is also important to use existing high and rigid buildings for evacuation shelters.

Okushiri Island suffered severe damage by the 1993 Hokkaido Nansei-oki Earthquake Tsunami. The tsunami of 10m high attacked the south part of the island. After the tsunami, high seawalls were constructed along the coast to protect coastal low-lying areas. However, a fishery port was out of the seawalls to keep its fishery function. For evacuation of the persons working at the port from tsunamis, a new terrace was constructed as a tsunami shelter. The terrace was usually used for fishery activities.

KNOW THE TSUNAMI RISK AT THE SITE

Using the tsunami run up map each settlement has to decide safe zone and no safe zone for habitations. This can be included as part of the land use planning for building permissions. Other parameters to be considered are, •

Elevation of settlement from coast

•

Distance of proposed /existing settlement from the coast.

•

Type of the settlement

•

Coastal bathymetry in front of the settlement

•

Percentage of vegetation in front of the settlement

•

Percentage of sand dunes in front of the settlement.

•

Presence of backwaters

9.2 AVOID NEW DEVELOPMENTS IN TSUNAMI RUN-UP AREAS

Avoiding or minimizing the exposure of people and property through land use planning can mitigate tsunami risk most effectively. Development should be prevented in high-hazard areas wherever possible. Where development cannot be prevented, land use intensity, building value, and occupancy should be kept to a minimum. In areas where it is not feasible to restrict land to open-space uses, other land use planning measures can be used. These include strategically controlling the type of development and uses allowed in hazard areas, and avoiding high-value and high-occupancy uses to the greatest degree possible.

- 75 -

PLANNING COASTAL AREAS FOR TSUNAMI

Strategy 1: Designate Tsunami Hazard Areas for Open-Space Uses

The designation and zoning of tsunami hazard areas for such open-space uses as agriculture, parks and recreation, or natural hazard areas is recommended as the first land use planning strategy to consider. This strategy is designed to keep development at a minimum in hazard areas. It is particularly effective in areas that have not yet experienced development pressure. It is obviously more difficult in areas that are already partially developed or that have strong development pressures.

Strategy 2: Acquire Tsunami Hazard Areas for Open-Space Uses

Open-space acquisition has several advantages over strictly regulatory approaches such as zoning. Acquisition ensures that the land will be controlled by a public agency or nonprofit entity, and it removes any question about a regulatory taking. The primary disadvantage to acquisition is cost.

Strategy 3: Restrict Development through Land Use Regulations

In areas where it is not feasible to restrict land to open-space uses, other land use planning measures can be used. These include strategically controlling the type of development and uses allowed in hazard areas, and avoiding high-value and high-occupancy uses to the greatest degree possible.

PLANNING COASTAL AREAS FOR TSUNAMI

9.3 THE ROLE OF LAND USE PLANNING IN REDUCING TSUNAMI RISKS Land use planning in communities guides the location, type, and intensity of development and can, therefore, be used to reduce the community’s exposure to tsunami hazards.

Understand Locational Context

Opportunities for reducing tsunami risk differ depending on local circumstances, so a onesize fits- all approach cannot be used. The presence or absence of development within tsunami hazard areas will determine the type of planning approach that is feasible.

Understand Trade-Offs Mitigation often means making trade-offs between or among competing goals when dealing with land use planning issues and tsunami hazards.

Review and Update Existing Zoning, Subdivision, and Other Regulations

Land use policies and programs should address tsunami hazards as part of a comprehensive tsunami mitigation program. Such an update should focus on the location and vulnerability to damage of existing and planned land uses in the community, including the following: • residential • commercial/visitor-serving • industrial (general) • industrial (hazardous materials) • public facilities (transportation and water systems) • critical facilities and systems (communication, emergency response, electrical power, water supply, and natural gas systems)

- 77 -

PLANNING COASTAL AREAS FOR TSUNAMI

9.4 PLANNING FOR POST-TSUNAMI RECONSTRUCTION Disasters create the opportunity to eliminate nonconforming uses and reshape existing patterns of development to minimize future losses. On the other hand, they can also create enormous pressure to rebuild the community quickly and exactly as it was before the disaster. These rebuilding issues should be addressed through the land use planning process before a disaster strikes so that a community is prepared to deal with rebuilding issues in the event of a disaster.

RESETTLEMENT PLANNING

1. While planning a new settlement, an in-depth study of the existing settlement pattern is necessary so as to recreate layouts and common spaces, which have evolved over time and are culturally sensitive.

2. However the above traditional layout pattern must necessarily be integrated with disaster mitigation aspects, so that risks are not again recreated.

3. Size and layouts of homesteads should provide space for carrying out the daily activities a fishermen household in coastal Tamil Nadu practice and should provide allowance for lateral and vertical growth.

4. Provisions for adequate lifeline infrastructure and common amenities like drinking water, sanitation, electricity, proper approach roads, school cum multi-hazard resistant shelters, etc. as appropriate depending upon the population have to be made.

5. Shore protection works –naturally e.g. through sand dunes, coastal plantations like casuarinas, mangroves, etc. and artificially e.g. through tripods and tetra pods may have to be introduced specially in case of redevelopment for existing settlements.

9.5 SITE PLANNING STRATEGIES TO REDUCE TSUNAMI RISK S•1: Avoiding Avoiding a tsunami hazard area is, of course, the most effective mitigation method. At the site planning level, this can include siting buildings and infrastructure on the high side of a lot or raising structures above tsunami inundation levels S•2 Slowing Slowing techniques involve creating friction that reduces the destructive power of waves. Specially designed forests, ditches, slopes can slow and strain debris from waves. S•3 Steering Steering techniques guide the force of tsunamis away from vulnerable structures and people by strategically spacing structures, using angled walls and ditches, and using paved surfaces that create a low-friction path for water to follow. S•4 Blocking Hardened structures such as walls, compacted terraces and berms, parking structures, and other rigid construction can block the force of waves.

PLANNING COASTAL AREAS FOR TSUNAMI

CASE STUDY: SUSTAINABLE DEVELOPMENT PLAN FOR TSUANMI AFFECTED COASTAL AREAS OF CUDDALORE, PLANNING PROJECT,M.PLAN 2004-06’ BATCH

After doing a detailed study on the coastal stretch of cuddalore district one settlement was taken for the detailed planning and the following proposals are given

• Site should be located preferably at high lands either at 350M from the HTL or+3M • It should be placed away from the CRZ zone -500M. • Settlement pattern should be perpendicular to the coast line. • Orientation of houses should be across the coast. • Restriction of kutcha houses near the coast. • Artificial barriers to be created along the coast. • Casuarinas should be planted as it could reduce the wave intensity. • An elevated work space about 10’ high which could with stand the wave erosion. • Can be used for net knitting, drying fish and other purposes. • Boats docked under the stills. • Strong concrete Catch poles for holding in case of tsunami. • Creepers spread over the sand stretch as to provide grip for the sand. • Creation of vegetation and sand dunes as the natural barriers. • Gravels dumped through out the stretch as barriers.

The Hilo Downtown Development Plan was adopted in 1974 to guide efforts to revitalize the downtown core of Hilo, Hawaii.

•

The Plan established a Safety District based on the 1946 and 1960 tsunami inundation lines.

•

All redevelopment in the Safety District was subject to urban design and building design standards. Any structure below the 20-foot elevation contour line was required to design to withstand the force of a major tsunami.

•

A Parking District was also designated in the Plan to provide parking for downtown businesses and to use parking structures as a protective barrier from a tsunami for inland structures.

INFRASTRUCTURE AND CRITICAL FACILITIES The average coastal population density is 432 persons per sq. km as against 256 persons for the entire country. Apart from protecting the community and resources, there is a need for providing necessary infrastructure facilities for the communities to maintain a better standard of living and their economic development.

1. They are waterfront dependent and the design can mitigate the vulnerability to such an extent that the resulting facility will perform as needed;

2. Risk is reduced through mitigation and emergency planning measures;

3. The need for the facility outweighs the consequences of its loss during a tsunami (e.g., a small hospital in a remote, tsunami-prone area may be justified because it needs to be close to the population for routine emergencies).

TSUNAMI: WILL WE BE READY FOR THE NEXT ONE? 15 January 2005 NEW SCIENTIST

Local authorities can try to ensure that all critical infrastructure, such as water plants and hospitals, are located outside the tsunami danger zone. This would avoid problems like those in Kalpakkam in India, where a nuclear power plant was closed down for days after the tsunami sent salt water gushing into its pumping station.. Seawalls, dykes and so on may reduce the damage, but they are very expensive and may adversely affect the environment. Protective measures such as these may be used in areas that contain essential infrastructure, such as the Kalpakkam Nuclear Power Plant in Tamil Nadu, India. Not just four walls and a roof Special structures such as hospitals and shelters that come very close to the sea can be built up to a height of three story’s. Building standards for common facilities such as hospitals, schools and community centers should be made very stringent, to resist even the worst of tsunamis. The DAE and the Indian government are building another nuclear power plant at Koodankulam (near the southernmost tip of India) that also sits on the Bay of Bengal badly affected by the tsunami. Neighboring coastal villages such as Idinthakarai, Kooduthazhai, Koothankuzhi, Uvari, Koottapuli have all been damaged by the tidal waves.

Should we place infrastucture facilities which does not require foreshore near the coast?

Are these critical infrastructure the life line during a disaster?

If the Koodankulam nuclear power site is this vulnerable, should we go ahead with the construction of this mega-nuclear site?

Chapter 10 TSUNAMI WARNING AND COMMUNICATION SYSTEM 10.1

THE PRESENT STATUS OF TSUNAMI WARNINGS IN INDIA.

Tsunami is least probability event in India. As such, there is no codal provisions of Tsunami warnings in India as yet though, there is a good seismological network in India to record any earthquake within the country and its neighborhood.

The need of a Tsunami Warning

Centre (TWC) in India is now being conceptualized at the Government of India level.

The Department of Ocean Development in Cooperation with Departments of Space and Science and Technology is evolving a plan of tsunami warning system in the Bay of Bengal and the Arabian Sea. The data from observing points to Warning Centre(s) will be sent through satellite links,

Specific systems called Deep Ocean Assessment and Reporting of

Tsunamis (DART) using Bottom Pressure Recorder, acoustic modem, acoustic release system, battery pack bolted to platform and float action and recovery aids will be deployed.

10.2

INTERNATIONAL

STATUS

OF

TSUNAMI

WARNING

AND

COMMUNICATION SYSTEM Present techniques of Tsunami prediction are severely limited. The only way to determine, with certainty, if an earthquake is accompanies by a Tsunami, is to note the occurrence and epicenter of the earthquake and then detect the arrival of the Tsunami at a network of tide stations. While it is possible to predict when a Tsunami will arrive at coastal locations, it is not yet possible to predict the wave height, number of waves, duration of hazard, or the forces to be expected from such waves at specific locations.

Tsunami Warning System is based on the concept that Tsunamis travel at much slower velocity (500 to 700 km per hour or 0.20 km/sec) as compared to seismic waves (6 to 8 km per second). That is seismic waves move 30 to 40 times faster than Tsunami waves. Thus, after the occurrence of a damaging earthquake and quick determination of epicenter, warning time of a few minutes to 2 to 3 hours is available depending upon the distance from

- 91 -

PLANNING COASTAL AREAS FOR TSUNAMI

the epicenter to the coast line. This time can be utilized for warning the coastal community if quick detection and rapid communication systems are established.

10.2.1Tsunami Warning System

Following most common methods of detection is in use:• Japan has a network of land/sea sensors that records seismic activity and feeds information to a national agency able to issue evacuation warnings within a minute of occurrence of any earthquake.

Earthquake warning issued by Japan

Meteorological Agency are relayed via satellite to the Municipal offices and automatically broadcast from several sets of loudspeakers. • Pacific Ocean issues warnings of tidal waves heading in a particular direction. • Presently land and sea based sensors connected to satellite based link are available. • Satellite telemetry is used for data collection and dissemination; receive and display of Tsunami warning utilizing existing Geostationary operational Environmental Satellite (GOES) and Data Collection Interrogation System (DCIS). An earthquake activates seismic instrument, which transmits signal to the GOES platform which responds automatically transmitting an alert code to an active device at warning site. • Developing Tsunami and earthquake data base verification, Tsunami model, preparation of hazard assessment maps for the coast line combing historical and modeling result, establishment of seismic and tidal sensors using satellite telemetry to provide early warning information. • Extensive network of seismic and tidal station, as well as communication systems, to ensure that the warning information is prompt and accurate.

- 92 -

PLANNING COASTAL AREAS FOR TSUNAMI

System performs with detection of an earthquake, which has required magnitude to trigger the alarm attached to the seismograph.

The alarm thresholds are set so that ground

vibrations of the amplitude and duration associated with an earthquake of approximate amplitude 6.5 or greater or Richter scale anywhere in Pacific will cause them to sound.

10.2.2 The Tsunami Warning System

Tsunami Warning System (TWS) in the Pacific, comprised of 28 participating international Member States, has the functions of monitoring seismological and tidal stations throughout the Pacific Basin to evaluate potentially Tsunamigenic earthquake and disseminating Tsunami warning information.

The Pacific Tsunami Warning Center (PTWC) is the

operational center of the Pacific TWS.

Located near Honolulu, Hawaii, PTWC provides

Tsunami warning information to national authorities in the Pacific Basin.

10.2.3 Tsunami Warning Centers

As part of an international cooperative effort to save lives and protect property, the National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service operates two Tsunami warning centres. The Alaska Tsunami Warning Center (ATWC) IN Palmer, Alaska, serves as the regional Tsunami Warning Center for Alaska, British Columbia, Washington, Oregon, and California.

The Pacific Tsunami Warning Center in Ewa Beach, Hawaii, serves as the regional Tsunami Warning Centre for Hawaii and as a national/international warning center for Tsunamis that pose a Pacific-wide threat. This international warning effort become a formal arrangement in 1965 when PTWC assumed the international warning responsibilities of the Pacific Tsunami Warning System (PTWS). The PTWS is composed of 26 international Member States that are organized as the International Coordination Group for the Tsunami Warning System in the Pacific.

- 93 -

PLANNING COASTAL AREAS FOR TSUNAMI

10.2.4 Tsunami Watch and Warning Dissemination

The objective of the PTWS is to detect, locate, and determine the magnitude of potentially Tsunamigenic earthquake occurring in the Pacific Basin or its immediate margins. Earthquake information is provided by seismic stations operated by PTWC, ATWC, the U.S. Geological Survey’s National Earthquake Information Centre and international sources. If the location and magnitude of an earthquake meet the known criteria for generation of a Tsunami, a Tsunami warning is issued to warm of an imminent Tsunami hazard.

The

warning includes predicted Tsunami arrival times at selected coastal communities within the geographic area defined by the maximum distance the Tsunami could travel in a few hours. A Tsunami watch with additional predicted Tsunami arrival times is issued for a geographic area defined by the distance the Tsunami could travel in a subsequent time period. If a significant Tsunami is detected by sea-level monitoring instrumentation, the Tsunami warning is extended to the entire Pacific Basin.

Seal level (or tidal) information is provided by

NOAA’s National Ocean Service, PTWC, ATWC, university monitoring networks and other participating nations of the PTWS. The International Tsunami Information Center, part of the Intergovernmental Oceanographic Commission, monitors and evaluates the performance and effectiveness of the Pacific Tsunami Warning System. This effort encourages the most effective data collection, data analysis, Tsunami impact assessment and warning dissemination to all TWS participants.

10.2.5 Tsunami Warning Dissemination

Tsunami watch, warning and information bulletins are disseminated to appropriate emergency officials and the general public by a variety of communication methods.

-Tsunami watch, warning and information bulletins issued by PTWC and Atlantic Tsunami Warning Centre (ATWC) are disseminated to local, state, national and international users as well as the media. These users, in turns, disseminate the Tsunami information to the public, generally over commercial radio and television channels.

-The NOAA Weather Radio System, based on a large number of VHF transmitter sites, provides direct broadcast of Tsunami information to the public.

- 94 -

PLANNING COASTAL AREAS FOR TSUNAMI

-The US Coast Guard also broadcasts urgent marine warnings and related Tsunami information to coastal users equipped with medium frequency (MF) and very high frequency (VHF) marine radios.

-Local authorities and emergency managers are responsible for formulating and executing evacuation plans for areas under a Tsunami warning. The public is advised to stay-turned to the local media for evacuation orders and latest Tsunami warnings. People are advised not to return to low lying coastal areas until all clear signals are issued from the Warning Centre.

10.3

SOME CONCEPTS OF WORK PLAN FOR THE TSUNAMI WARNING SYSTEM IN INDIA

•

Assumption: Least probability event. Return period once after several hundred years. No

parallel in recorded history like Tsunami of 26 December 2004. Proposed system should be sustainable and cost - effective. •

Observational system should be of multi use type (Oceanography, Meteorology,

Geophysics) •

Policy decision: Codal Provision to issue Tsunami warning.

•

Identification/Establishment of Nodal Department

•

Identification of Vulnerable area

•

Fixation of critical value for the issuance of Tsunami warnings (Magnitude 7.0 or above in

Richter Scale ) •

Cost effective and sustainable communication system (Radio and Satellite based

communication)

Chapter 11 INSTITUTIONAL FRAMEWORK 11.1 INTRODUCTION An organizational network is made up of agencies whose activities are determined by human settlements. The organizational system is the way in which the government connects agencies so that specific decisions will be carried out and specific objectives attained. In any governmental organization, two types of system are present. One is the vertical authority where instructions are passed down from the upper levels for implementation to lower levels and the other is the horizontal authority in which units from sector rely on the operation of units in the other sector for successful implementation. For developmental initiatives at any spatial level, the following Institutional agencies are involved,

11.2 HIERARCHY OF EXISTING INSTITUIONAL SETUP District Planning Committee consolidates plans prepared by the panchayats and municipalities in the district and prepares a draft development plan for the district as a whole. It is a statutory body and serves as an excellent tool to integrate the plans of urban areas and rural areas. It provides a platform for conflict reservations in the matter of common resources and control of transitional areas. Collector is responsible for a very vast area and

- 96 -

PLANNING COASTAL AREAS FOR TSUNAMI

has considerable scope for exercising control, power, influence and authority. The district collector is the Inspector of the Panchayats. Out of three- tier panchayats the village panchayats are being empowered to undertake works relating to any developmental activity, maintenance and electrical. However, the panchayats are advised to obtain administrative and technical sanction from the competent authorities. The government has stipulated that the administrative sanction of the collector/inspector is required for particular scheme or particular fund above a particular limit. The Block Development Officers (BD0s) are the controlling mechanism below the district level.

11.3 LOCAL ADMINISTRATIVE SYSTEM OF GOVERNANCE Local Government is the lowest in the scheme and also the smallest in jurisdiction. Local Government is described as that under which the people of the locality possess a certain responsibility and choice in administration of local public affairs and in raising of required finance to meet their expenses. Local Self Government freely elected, which, while subject to supremacy of the National Government, are endowed in some respects with some power, discretion and responsibility and which they can exercise without control over their decisions by higher authority.

11.4 RELEIF EFFORTS Local Government is the lowest in the scheme and also the smallest in jurisdiction. Local Government is described as that under which the people of the locality possess a certain responsibility and choice in administration of local public affairs and in raising of required finance to meet their expenses. Local Self Government freely elected, which, while subject to supremacy of the National Government, are endowed in some respects with some power, discretion and responsibility and which they can exercise without control over their decisions by higher authority. Although the GOI and the State Government Administration were caught unawares by the Tsunami, they responded quickly.

11.4.1 CENTRAL GOVERNMENT

• The Ministry of Home Affairs (MHA) of the Government of India was designated as the Nodal Agency for coordinating relief in the affected areas. • A National Crisis Management Committee (NCMC) was established under the Cabinet Secretary to draw up an emergency relief plan and to review those efforts. • Funds were allocated to the affected areas from the National Calamity Contingency Fund.

11.4.2 STATE GOVERNMENT

• Revenue Department under the Relief Commissioner coordinated rescue and relief efforts through relevant district collectors with assistance from the police force, fire and rescue services, medical and health services and all other associated departments. • The district administration along with Local Self Government coordinated relief works at the local level.

CATEGORIZATION OF RELEIF MEASURES

The Relief Measures are categorized into three... • Immediate short term • Medium term • Long term

IMMEDIATE SHORT TERM MEASURES

• Disposed dead bodies, moved obstacles and rescued People. • Moved People to safer locations. • Prevention of outbreak of epidemics. • Construction of temporary Rehabilitation Shelters and toilets. • Distribution of Food and Medicine to the affected populace. • Restoration of crucial communication and infrastructure, power and water supply. • Medical teams with paramedical staff working in the affected areas.

MEDIUM TERM MEASURES

• Commencement of the Trauma Management. • Rehabilitation shelter and their associated infrastructures. • Restoration of the Economic Activity. • Reestablish the productivity of affected areas. • Medical teams with paramedical staff working in the affected areas. • Effective waste management and natural resource use.

LONG TERM MEASURES

• Permanent reconstruction and rehabilitation for the affected populace. • Sustainable strategies for long term ecological management and human welfare. • Reestablish the productivity of affected areas. • Medical teams with paramedical staff working in the affected areas. • Effective waste management and natural resource use.

NON - GOVERNMENTAL ORGANISATION/ CBO's

• Non-Governmental organizations across India and abroad responded immediately to the affected areas. • They lived with one another to adopt entire settlement and people in their recovery process. • They operated in sectors ranging from health, psycho social counseling, shelter, education, livelihood and environment. • Community based networks and social hierarchies were already in existence in the affected areas were helpful during the calamity. • Relief and Rescue operations were initialized and did not wait for the arrival of the outside help.

- 99 -

PLANNING COASTAL AREAS FOR TSUNAMI

11.5 NGO’s OPERATIONS The disasters local area specific dimension has more relevance to the NGO's. This is due to the fact that the grass root feel and the close contact they have with the lifestyle and ethos, of the affected lot. They initiated the following: • Immediate Rescue operations initialized. • Provision of Food, Clothing, Medicines and other basic amenities. • Aiding the construction of Temporary Rehabilitation Shelters. • Relocation of the affected populace in their own short stay homes/orphanages. • Psychological counseling to the affected lot. • Training SHG's to aid in the affected areas.

11.6 OBSERVATIONS • Relief measures were effective in the immediate short term ones. • For the Medium and Long term measures, priority Action Plans were not crystallized • Rapid Assessments and ongoing monitoring were not duly addressed during recovery phase. • Identification of priorities and opportunities for environmental restoration and improved management of the coastal eco system to generate multiple benefits for different natural resource, user groups were not initiated yet. • The performance of the municipality was moderately fair .

11.7 CONCLUSIONS • Lack of ascertained networks and institutional setup for the immediate relief and rescue operations. • Distribution of immediate relief measures was not equitable along the stretch and even within the settlements. • Institutional Networks for Planning, Execution and Management and Implementation for long term needs are to be identified.

First preliminary report of the damage to coral reefs and related ecosystems of the western and central Indian Ocean caused by the Tsunami of December 26 (PDF 16.8kb) CORDIO CORDIO is a project to study the status of coral reefs in the central and western Indian Ocean. CORDIO was initiated after the massive coral bleaching in 1997/98 and has contributed to collection and compilation of monitoring data from coral reefs in 11 countries in the region. A substantial part of the work is focusing on developing alternative livelihoods for people affected by degraded coastal ecosystems. In the planning and implementation of its program, CORDIO is collaborating closely with IUCN (The World Conservation Union) in the South Asian region. The following is an account of observations by experts in the CORDIO/IUCN network in Sri Lanka, India, Maldives, Seychelles and Kenya during the first 10 days following the Tsunami.

™

Brief Summary of Indian Ocean Reefs relative to the 26 December 2004 Tsunami 5 January, 2005 General summary – many coral reef people associated with the GCRMN consider that the tsunami surges will have caused little to moderate damage to the corals, but that the backwash with large amounts of sediment and debris will be the major damaging factor. The large amounts of cloth (towels, clothing, sheets, curtains) will remain on the reefs for months causing major reef loss. Schooling fish were probably lifted onto the land and there are reports of fish inside rice paddies; the loss of coral habitat will be the long-term concern for target fish of fishing communities Full Statement (PDF 14.6kb)
