摘要
大连及邻区在1981~1991年间发生了多次中强地震。本文作者应用地磁加卸载响应比方法对大连台1981~1991年地磁资料进行处理。在研究大连台P(Z)值的异常变化与该台周围中强地震关系的基础上,给出映震异常的定量指标及预报效果。
Using of the method of field geomagnetic load-unload response ratio, data of geomagnetic vertical-component daily ranges of Dalian seismic station from 1981 to 1991 are processed. The quantitative indexes of response-earthquake and forecasting results can be obtained while determining the relationship between the P(z) value anomalies variation and the medium-strong earthquakes in Dalian area.
