摘　　要：在我国辽阔的渤海、黄海、东海和南海，只有渤海发生过７级以上地震，而面积狭小的台湾海峡却发生４次７—８级地震，数十次５—６．９级地震。是我国大陆近海地震活动强度最大，频度最高的地区。台湾海峡位于欧亚大陆板块和太平洋菲律宾海板块的结合地带，地壳运动强烈。海峡中北东、北西向断裂发育，第四纪以来，上述断裂均有强烈的活动。在这种地质构造背景下，发生了历史上一系列强烈地震和这次７．３级地震。Among the Bo sea,Yellow Sea,East sea and South sea,only earthquakes With M ≥7 happened in Bo sea,however,4 earthquakes with M=7-8 and tens of M=5-6 Occurred in Such Small Taiwan Strait,Where has the biggest strength and highest frequency in our country.Taiwan Strait is located in the intersection of Eurasia plate and Pacific Philippine sea plate in which there is strong cruatal movement.Faults in NE and NW are actively developed,and have been active since Quaternary, the historical strong earthquakes and the recent M=7.3 earthquake took place in such background.
