华北中强地震前锦州地震台形变异常特征研究

Research on the characteristics of deformation anomaly at Jinzhou Seismic Station before the middle-strong earthquakes in North China

应用锦州地震台井下摆倾斜仪的观测资料,对大华北地区中强地震前的形变异常形态及特征进行了初步分析与探讨。

With the deformation observation data recorded by the bore-hole pendulum inclinometer in Jinzhou Seismic Station, the form and characteristics of deformation anomalies befor strong earthquakes occurred in North China is primarily analyzed and discussed.
