Sichuan earthquake
Introduction Sichuan earthquake
Date:May 12, 2008 Time:14:28:01.42 CST (06:28:01.42 UTC) Magnitude:8.0 Ms (China Seismological Bureau) / 7.9 Mw(USGS) Modified MercalliScale: IX Depth:19 kilometres (12 mi) Epicenter location:(Latitude:31.021, 103.367) Wenchuan County in Sichuan province
Introduction Sichuan earthquake
Countries/regions affected: China Tsunami:None Aftershocks:so far 94 strong aftershocks over 7,000 weak aftershocks Casualties:65,080 (dead, 20th deadliest earthquake) 360,058 (injured) 23,150 (missing) (as of May 26, 2008 12:00 CST)
Introduction •
The earthquake was felt as far away as Beijing (1,500 km away) and Shanghai (1,700 km away), where office buildings swayed with the tremor.
•
The earthquake was also felt in nearby countries.
•
The earthquake left about 4.8 million people homeless, though the number could be as high as 11 million.
•
It was the deadliest and strongest earthquake to hit China since the 1976 Tangshan earthquake, which killed at least 240,000 people.
•
On May 25, a major aftershock of 6.0 Mw hit northeast of the original earthquake's epicenter, in Qingchuan County, causing 8 deaths, 927 injuries, and the collapse of thousands of buildings.

Sichuan earthquake
Reason • It is believed that the reason of Sichuan earthquake is the movement of Indian plate. • The Indian plate moved northward and collide with the Eurasian plate.
Reason Because of the colliding of Indian plate and Eurasian plate , Tibetan Plateau uplifted quickly .
The E art hq uak e As the result ,the convergence of crustal material moved slowly from the high Tibetan Plateau to the east. The material then collided with the strong crust underlying the Sichuan Basin and southeastern China .
Reason
With the continuously colliding of the crustal materials and the strong crust, a great power had formed . Finally, the great power was released in Wenchuan . This is one of the reasons about the happening of this earthquake.
2nd Reason • The second reason of the Sichuan Earthquake is reverse faulting. • The source of power to push them towards each other is the northern colliding of Indian plate and Eurasian plate . • It is believed that the pressure spreading and releasing process was slow ,therefore the shock wave was more concentrated and more destructive.
3rd Reason • The final reason is the depth of earthquake focus. • In the case of Sichuan Earthquake, the depth of earthquake focus was only 19 kilometers . • As the result, the earthquake became more destructive.

Areas affected
• • • •
Sichuan Earthquake is known as the most destructive earthquake since the 1976 Tang Shan earthquake . Felt (VII) at Chengdu, (VI) at Xi'an and (V) at Chongqing and Lanzhou. Felt in much of central, eastern and southern China, including Beijing, Guangzhou, Nanjing, Shanghai, Tianjin, Wuhan and in Hong Kong. Also felt in parts of Bangladesh, Taiwan, Thailand and Vietnam.
Casualties •
At least: 65000 people were killed . 20000-30000 lost. 360,058 injured
Economic loss
• Landslides blocked roads and buried buildings. • 80% of the buildings were destroyed. • 8 schools were toppled in Dujiangyan. • At least 5 million people without housing
.
• losses at US$1 billion from the earthquake already. • estimated total damages exceed US$20 billion .
Result
The environmental sanitations are very bad in those place suffering from the earthquake. Most disaster areas are backward Victims have no clean water ,food, and hygiene facilities . Victims are baring the risk of the spreading of diseases.
Effect
• Formation of Landslide dam • Due to the earthquake, landslide formed and blocked the river channel . • Water then was then trapped in the space between two or more mountains, Landslide dam was formed.
Effect • Since there are many dead bodies, dead animals all around • Poor hygiene • Lack clean water • Infectious diseases may occur

How c an we h elp?
• Donate money • Donate blood • Send them some basic materials • Pray for them
Compare with Tangshan earthquake (1976)
The Sichuan earthquake (2008) had the same measurement on the richter scale at 8.0 in magnitude with Tangshan earthquake (1976)

Conclusion • It was a very destructive disaster • Arise HK people’s nationalism • It was lucky that many countries provided emergency medical teams. • many people donated large amount of money to carry out relief work • Important to improve the earthquake-proof materials • Need to apply flexible construction designs
