摘要
根据微震相对频度原理提取微震信息,分析了泾阳震群的活动特征.应用相关分析法探讨了泾阳地区的震群活动与冯村水库库容变化和口镇—关山断裂活动的关系,认为泾阳地区的震群活动是构造地震,是区域应力场控制的结果,与水库无关.
Bases on relative frequency of small earthquakes,the seismic information of Jingyang earthquake clusters is obtained and the characters of the clusters are analized.Using correlative analysis method the relationship among the earthquake clusters,the water storage in Fengcun reservoir and the tectonic activity of Kouzhen-Guanshan fault in Jingyang region is discussed.The result shows that the earthquake clusters in Jingyang region are tectonic earthquakes,controlled by regional stress field,and have no relation with Fengcun reservoir.
