Tsunami disaster in China

Tsunami disaster and its risk in China are analyzed from its physical property and occurring conditions.The probability of tsunami taking place in the Bohai Sea,Yellow Sea and East China Sea is small,and tsunami of Pacific Ocean has slight influence upon East coast of China.But tsunami generated southward could influence southeast coast of China widely.The potential sources of tsunami are large earthquakes in western Philippine,volcanic eruptions in Sunda Strait of Indonesia and large submarine landslides in the South China Sea.Although the possibility of tsunami impact on the coast of China are small,the magnitude of m=2 of tsunami with wave height of 5 meters would threaten the coastal areas that contribute to 25% GDP of the whole China mainland.In the view of hazard,it is possible to have small tsunami accompanied with large disaster.
