The Historical Of Krakatau Volcanoe

THE HISTORICAL OF KRAKATAU VOLCANOE AND WE ARE ORGANISE TRIP TO VOLCACOE STILL ACTIVE AND HAVING OWNER THE BOAT STARTING FROM CARITA-WEST JAVA-BANTEN INDONESIA AND LARGES SPACE AND BEAUTIF UL VIEWS AND DIFFERENT LANGUAGE AND AND TO CHANGE ETNICAL CULTURE AND MOV ING INDONESIA ASSOCIATION. The Krakatau complex is situated in the sunda strait,lampung province Indonesia between 105’27’44’’ longitude and 6’03’0’ longitude and approximately 60 km NW of carita.(figure) the Krakatau volcanoe consistof four island: -Rakata island,located in the most southern part,triangular in shape with the highes point being 813m -sertung island,in the northwest part of the group with the heights poin of 182m -panjang island,located in east part of the island groupwith the highestpoint of 132m -anak Krakatau(Krakatau child),located in the midlle part of the island groups with the highest point of the avtive cone reaching 201.5m(july 1983). Krakatau volcanoe is one of approximately 130 volcanoe that occur in the 6000 km Long chain of island that make up the Indonesian are.this nare is produced by the collision of the Indian Australian platen to the south as it converges with and slips benath the eurasion plate to the .geologist call this zone convergence a SUBDUCTION ZONE ( figure 2& attachment).as the Indian Australian plate clips deeper into the upper region of the earth,partial of rock within the subducted plate occur and MAGMA is produced.generally this

process occur within the upper few hundred km’s of the earth outer shell or LITHOS PHERE magma produced in this way is usually less dense than enclosing wall rock and is able to rise buoyantly towards the surface. Some magma eventually erupts onto the earth’s surface produced a volcanoe the time needed to form volcanoes is measured in hundred of thousand to millions of year,a time that is short in a geological sense,but one that is beyond our human experiences.occasionally volcanoe,do change considerable during the course of a human lifetime. To day we will see that Krakatau has under ground a large amount of change since it’s major eruption in 1883. THE 1883 KRAKATAU VOLCANOE ERUPTION: The 1883 eruption of Krakatau volcanoe was among the larges that have occurred in historical times and it caught the attention of the world in a way than no other eruption in history had done. On August 26,1883 the big bang came (figure4.)for 19 hours the most violent explotions ever ,force of 100.000 hydrogen bombs tore Krakatau apart.the island was invisible behind a giant wall of smoke ash, fire and pumice the thunder of the explosion turned into a continuous infernal roar. Krakatau volcanoe the ejected matter much quicker than it could be replaced from the c enter of the earth.eventually,yhe volcanoe exhausted its magma contents,leaving cubic mile of empty chamber below the island. On August 27 krakatau’s cone coved in three quarter of the island,17sq km of surface,collapsed into the belly of the earth below.millions of the gallons of sea water Were than sucked into void.all along the coasts of west java and southern sumatera the sea receded at a speed of a 18 km’s per hours.

Below the remnants of the Krakatau volcanoe the water formed millions of tons boiling rocks and magma, causing tremendous gas explosions.this triggered earth quakes on the ocean floor that catapulted the water back inland.the resulting killer waves raced at speed up to 525 km,per hou7rs and reached height of 41 meters. The explosions were heard 5500km’s away,from srilangka to perth.giant aves crashed ashored and destroyed hundred of town village,reachind almost 15 km inland in some places.waves were felt in the englist channel,16,500 km’s away from Krakatau over 36,000 people killed an injured. Debris from krakatu, blown appro ximatelly 40 km’s upward,traveled around the earth several time,blanketing the whole of the globe’s surface (figure 5).the surrounding area was dark for 3 day.pressure waves from the blast circled the earth over time. POST 1883 KRAKATAU VOLCANOE ERUPTION All that remains of Krakatau volcanoe to day is a 750 m stump,where the 450 cone stood,lies 275 meters of sea water.the 120 meters cone also disappeared. But the story of Krakatau is not finished. In 1927, in a middle of submarine crater a new volcanic island began to rise from the sea where the old island had existed.in 1942,if reached 132 meters above the sea it was named ANAK KRAKATAU(Krakatau child) The mountain of Krakatau child ( gunung krakatau)activity continues since then.in November 9,1992 thee the mountain of child Krakatau was erupting and was so far in along periode of

constant eruptions,commemorating it 110th anniversary in Au gust 1993. Explanation :organize tour to Krakatau volcanoe one day trip by boat landing on the child of krakatu swimming,snorkeling,lunch time to resting the return in the afternoon And then chould be stay over night and sleeping on the camping of research or exploring mountain volcanic and can staying some day or stay one week next couple week staying longer the hang price.
