摘要
利用地震活动因子A值,对青海省东部地区(监测能力强)小震活动进行空间扫描,分析了该地区中强以上地震前,地震活动因子A值的空间分布、演化特征及其与目标地震的对应关系,并对该方法的预报效能作出评价。
Spatial scanning of micro-earthquake activity in eastern Qinghai province is made by using seismcity factor A-value.Spatial distribution and its characteristics of A-value before medium-strong earthquakes are analyzed,and the predictive effect of this method is evaluated in the paper.
