摘要
介绍了怀来地震台体应变所处地质构造情况,根据怀来地震台体应变观测资料,分析了华北北部近年来中强地震及本区4.4级地震与体应变异常的关系,结果显示,怀来体应变异常与地震活动有较好的对应关系,且基本是短临异常。
We have first introduced geological structure in Huailai Station.Based on the observation materials,the analysis of relations between strong earthquake and volume strain anomaly in North China had been made. The results show that the volume strain anomaly is better correspondingto seismic activity in short term.
