文安5.1级地震的一些异常特征

THE CHARACTERISTICS OF ANOMALIES BEFORE WEN'AN MS5.1 EARTHQUAKE

摘要: 对文安5.1级地震的一些异常进行了分析和总结, 认为地震逆时针方向迁移可能是地震空间活动的一个基本特征, 其可作为背景异常。震前, 地磁交汇法出现的异常, 再次显示出该方法对地点预测的最大优势, 交汇点附近即是未来震中区。这些异常特征对我们认识地震和预测地震都具有一定意义。

Abstract: Based on the analysis to the anomalies of Wen'an Ms5.1 Earthquake, it is found that anticlockwise migration is a basic feature of earthquake activity, and it can be as a background anomaly.The anomalies obtained with geomagneticcross method before earthquake show some superior at the prediction of location, and the crossing point may be the potential epicenter area.
