摘要
在系统地研究了华北北部 5次中强以上地震前地下流体异常空间演化过程的基础上 ,分析了地下流体动态异常的迁移特征 .根据迁移特征和异常时间与震中距的关系提出了预测强震危险区的 5个标志和 3个步骤 ,并用几个震例进行了检验 .结果表明 。
The space evolution process of ground fluid anomalies before five medium strong earthquakes of northern part of North China is systematically studied. The anomalous migration feature is analyzed. On the basis of the migration feature as well as relation between anomalous time and epicentral distance, five signs and three steps for predicting risk region of strong earthquake are given,which are tested by three earthquakes.The results show it is possible to predict risk region of coming strong earthquake to a certain extent by using space evolution features of ground fluid anomalies.
