摘要
1999年 1 1月 1日 ,在浑源—阳原发生了 MS5.6地震。中国地震局综合观测中心根据首都圈中西部至晋北地区流动地磁出现的异常情况 ,应用差值年变率方法预测地震的异常判据和异常指标 ,着重对浑源—阳原 MS5.6地震前后流磁异常演化过程进行了异常追踪分析。对此次地震提出了较好的中短期预测。
An earthquake of M S 5 6 occurred in Hunyuan Yangyuan on November 1,1999.There were some anomalies of mobil geomagnetic surveys between middle west of the Capital Area and northern Shanxi province.Using the method of anomalous criterion and anomalous index of annual variation rate of difference value for predicting earthquake,we have made tracing analyses on evolutionary process of the anomalies before and after the event.We also proposed a good middle short term prediction for this earthquake.
