马尼拉海沟潜在地震海啸对我国华南沿海危险性研究OA北大核心CSTPCD
Impact of potential tsunami from Manila Trench along the South China coast
采用COMCOT模型建立南海多重嵌套网格对马尼拉海沟潜在震源进行数值模拟,评估马尼拉海沟地震海啸对我国华南附近海域的影响.敏感性分析结果表明:马尼拉海沟地震震源深度为33～40 km时,地震引发的海啸危险性最大;在此基础上,设置5种马尼拉海沟潜在地震海啸情景,其中情景二、四和五,其地震震级分别为Mw8.6、M8.8和M9.0,引发的海啸会严重威胁到我国华南沿海大部分海域,危险等级为Ⅲ-Ⅳ级,有淹没至严重淹没危险.
Multiple nested grid was applied using COMCOT model to simulate the hypothetical tsunamis triggered by Manila Trench in the South China Sea,and their impacts along the South China coast were assessed.Sensitivity analysis shows that the focal depth of the worst earthquake tsunami scenario is about 33～40 kr.Five earthquake scenarios along the Manila Trench were simulated.Scenarios 2、4 and 5,with the magnitude of Mw8.6、Mw8.8 and Mw9.0,respectively,may reach Ⅲ t…查看全部>>
