| 摘 要： | 闽粤两省强烈地震多发生在沿海地区，且福建南日岛至广东南澳一线的泉州－汕头地震带地震活动尤为突出。历史上东南沿海地震带曾发生过４次７级以上大地震，而其中３次都发生在泉－汕段海域，继华南地区本世纪著名的１９１８年广东南澳７．３级地震后，１９９４年９月１６日台湾海峡南部又发生７．３级强震，这在经济发达，人口稠密的闽粤沿海地区引起了极大关注。本文通过历史强震活动资料，分析闽粤沿海与台湾海峡强震在时间进程，

| Abstract: | Strong earthquakes in Fujian and Guangdong Provinces,mostly occurred around the coastal areas,especially with an outstanding seismicity on the Quanzhou Shantou seismic belt lying from Nanri Island,Fujian to Nan'ao,Guangdong.Historically,4 earthquakes occurred with magnitudes larger than 7 0 on the southeast coastal seismic belt,among which 3 ones took place in sea areas along Quanzhou Shantou belt.Following the 1918 Nan'ao Guangdong M 7 3 earthquake,which is most significant in South China in this century,an M 7 3 strong earthquake occurred in the south of Taiwan Strait on Sept.16,1994.It caused great concern in the economy developed and populated Fujian Guangdong areas.According to historical strong earthquakes,this paper analyses developments of strong earthquakes occurring around Fujian Guangdong coast and Taiwan Strait,in terms of time progress,strength scale,area distribution and spatial seismicity pattern;states strong earthquake activity features in historical and current seismicity development long effected by a regional geophysical field;analyses the complexity of tectonics which generates the coastal earthquakes and Taiwan Strait strong earthquakes;finally,probes into possible influence factors of the dynamic enviorment under which occurrence for strong earthquakes around Fujian and Guangdong coastal waters,as well as Taiwan Strait. |
