Study on the potential tsunami hazard of adjacent trenches in the southeast coast of China

  • 摘要: 针对中国东南沿海邻近海沟潜藏大地震的可能性,采用基于有限体积法的浅水波数值模型GeoClaw分别对琉球海沟和马尼拉海沟潜在9级地震进行海啸数值模拟研究。结果表明,琉球海沟和马尼拉海沟地震发生时都释放了巨大的能量,并以海啸波的形式向中国沿海传播。其中,琉球海沟地震引发的海啸波经东海大陆架传播3 h后到达福建北部,并在随后2 h内对浙江、上海、江苏沿岸地区造成影响。海啸波高普遍达到0.5 m以上,浙江、上海局部海岸地区达到1 m以上。而马尼拉海沟地震海啸传播过程通畅,2 h后到达海南沿岸,并依次影响湛江、澳门、香港、厦门、高雄等沿海区域。海啸波高普遍达到2 m以上,澳门、香港海岸地区达到5 m以上,面临严重危险等级。基于我国东南沿岸港口、核电站、钻井平台等海洋工程项目持续建设的考虑,需要对潜在海啸威胁进行研究并采取相应措施。
