摘要
从台湾海峡与台湾浅滩的地貌特征、区域构造格局、海峡盆地形成历史、深部构造与断裂构造、震源机制解以及地震活动等方面论述了台湾浅滩7.3级地震的发震构造,认为北东东向澎湖—北港隆起南侧断裂(义竹断裂)是该地震的发震构造。
The Yizhu fault in direction of NNE which located at south side of Penghu-Beigang rise is the causative fault for the earthquake of M 7.3 in the Taiwan shallow.This is discussed from the follows:the geomorphologic feature of the Taiwan strait and the shallow,regional structure pattern,history of the strait basin,deep structure and faults,earthquake focal mechanism and earthquake activities.
