山西大同—阳高5.6级地震前的地磁异常及预报

Geomagnetic Anomaly and Prediction before M5.6 Earthquake at Datong-Yanggao,Shanxi

对 1999年 11月 1日山西大同—阳高 5 .7级地震前的流动地磁、日变形态出现的异常及其间不断增强的磁暴进行了分析 ,叙述了用这些异常进行预测预报的过程 。

The shape anomaly of the daily variation of the mobile geomagnetic observation and the constant strengthening magnetic storm before the M5.7 earthquake at Datong-Yanggao on December 1,1999 were analyzed,the prediction course using the anomalies was recounted,and the conclusion was obtained that the daily shape variation anomaly of the mobile geomagnetic observation can be used for the short-term earthquake prediction.
