邯郸磁山井水氡异常与华北两次中强地震关系初探

Study on the relation of water radon anomaly observed in Cishan well of Handan with two earthquakes occurred in North China

大同6.1级和张北6.2级地震前,邯郸磁山井水氡值都出现趋势性高值异常变化。应用水氡异常的滑动平均值和从属函数的判定方法做进一步分析,结果表明,磁山井水氡值的中期异常与华北地区的这两次中强地震有较好的对应关系;对出现这种对应关系的机理进行了讨论。

some high value anomalies of water radon appeared in Cishan well of Handan before Datong M6.1 and Zhangbei M6.2 earthquake. The anomalies are analyzed with sliding mean and secondary function method. The results show that the medium term anomalies of radon are corresponding well with the two events. The mechanism of correspondence is also discussed.
