由于印尼苏门答腊 安达曼地震以及由它引起的海啸造成了大量人员伤亡, 与其比邻的巽他海沟俯冲带触发地震的可能性引起了真正的关注。我们已经计算了这个区域以及临近区域苏门答腊直立走滑断层的同震应力分布, 发现两个构造上的应力都增加了, 从而极大地提高了原已很大的地 Due to the large number of casualties caused by the Andaman earthquake in Sumatra, Indonesia, and the tsunami caused by it, the possibility of triggering an earthquake by the subducted Qaidam trench adjacent to it caused real concern. We have calculated the coseismic stress distribution in the Sumatran upright strike-slip fault in this area and in the immediate area and found that both structural stresses have increased, greatly increasing the previously large
