闽粤沿海地震形势的初步分析

A tentative analysis on earthquake situation along Fujian and Guangdong coasts

本文从地震学和地震地质学角度出发，讨论海峡7．3级地震对东南沿海地震带地震活动性的影响，着重分析了海峡7．3级震前的背景空区及其震后演变过程，并采用各种方法对闽粤沿海地区进行了时空扫描分析，提取异常指标。预测该地区未来地震活动的趋势，对缩小未来可能发生破坏性地震的时间、地点、强度范围具有一定的意义。

Basing on the seismology and seismogeology,the article discusses the influence of 7. 3 grade earthquake on the earthquake belt along the southeastern coast. It stresses not only on the seismic gap situation be fore the earthquake, but also the evolution after it happened. It uses various means to make an all-around analysis on the coastal area of Fujian and Guangdong Province. At the same time,it also points out the unusual target to forecast the earthquake trend of the said area. It is good to lessen the future constructive earthquake on the scope of time,space and intensity.
