马尼拉地震带海啸对广东沿海影响的数值研究——潮汐与海啸的非线性作用的影响

Numerical Study on the Effect of Guangdong Coast by Manila Seismic Tsunami-The Nonlinear Effects of Tides and Tsunamis

摘要:

基于COMCOT数值模型，建立了天文潮与海啸耦合数学模型，对日本“311”海啸进行了模拟验证。针对马尼拉地震带海啸，通过设计海啸震源的计算，分析广东省沿海海啸风险，从数值上得出了海啸引发的最大增水值以及海啸到达广东省沿岸的时间。

Abstract:

The coupling numerical model between astronomical tide and tsunami was built on the data of COMCOT model,which was verified by the Japanese "March 11" tsunami. And the tsunami source of Manila seismic tsunami was designed and computed to analyze the risk of tsunami which may happen in the Guangdong seacoast. According to the results,the maximum quantity of water increasing and the time of the tsunami arriving the Guangdong seacoast was calculated. The coupling simulation between astronomical tide and tsunami has significant meaning for evaluating the risk and early-warning of tsunami in the area of the Guangdong coast.
