2018年印度尼西亚帕鲁MW7.5地震构造背景与区域地震活动

Tectonic context and seismic activities of the 2018 MW7.5 earthquake in Palu，Indonesia

    摘要
  • 摘要: 2018年9月28日（北京时间）印度尼西亚苏拉威西岛附近发生MW7.5地震。通过对地震震源机制的分析得出，本次地震是由于摩鹿加海微板块内部浅层走滑断裂所致。历史地震和震后周边区域的地震活动特征分析表明，该区域进入了地震活跃期，板块之间的相对运动较为明显。地震引发海啸是此次地震造成人员死亡的主要原因。

     

    Abstract: The MW7.5 earthquake occurred near Sulawesi, Indonesia on September 28, 2018 （Beijing time）. Through research and analysis of the focal mechanism of the earthquake, it is found that the earthquake was caused by the shallow strike-slip fault inside the Molujiahai microplate. Historical earthquakes and continuous strong earthquake data analysis in the surrounding area after the earthquake show that the region has entered the seismically active period, and the plate movement is more obvious. The tsunami caused by the earthquake is the main cause of death.
