中文摘要:
      选取了一组代表性的南海海啸源,并分别使用COMCOT海啸模式,以数值模拟的方法对南海局地海啸源进行了数值模拟,从海啸的传播影响时间、波高和能量分布等角度,分析了如果南海发生地震海啸,不同海啸源将会对我国南海沿岸地区和南海岛礁造成的影响。通过敏感性试验证实,海啸波的强度受地震震级变化影响较大,因此,如果南海发生强震引发局地海啸,不同海啸源将会给我国南海周边及岛礁等不同区域造成严重损害。
Abstract:
      On the basis of the topography and historical seismic information of the South China Sea, many scholars at home, and abroad have investigated the source area of possible earthquakes and tsunamis on the South China Sea. In this study, on the basis of previous research results, the authors analyze the areas that may be a tsunami source, select a group of typical tsunami sources, simulate these tsunami sources with the COMCOT model, and assess the damage to coastal areas and reefs of the South China Sea from in terms of tsunami propagation time, wave height, and energy distribution. The sensitivity test confirmed that the intensity of the tsunami wave is considerably influenced by the magnitude of the earthquake. If a local tsunami is triggered by a strong earthquake, then it will cause considerable damage to different parts of the coastal areas and reefs of the South China Sea.
