THE CORRESPONDING RELATION OF GROUNDWATER LEVEL IN JIN SECOND WELL WITH THE DISTINCT EARTHQUAKES AROUND

摘要: 通过对晋2井动水位15年观测资料的清理,从多种观测信息中筛选出阶变型前兆异常,制定了阶变异常的标准,进而从阶变频率入手,提取阶变组异常作为周围中强以上地震的中短期前兆信息。通过R检验,认为晋2井动水位阶变异常与周围显著地震以及阶变组异常与周围中强以上地震均存在较好的对应关系。在实践中,利用晋2井阶变组异常,曾先后较好地预测了晋2井周围3次中强以上地震。Abstract: Through processing the 15 year's observational data of groundwater level in Jin Second Well,a kind of scalariform anomaly is extracted,and its anomaly standard is made.From the scalariform frequency,the medium and short term precursory anomalies corresponding to over moderately strong earthquakes around are picked up.The R-test shows that the scalariform and scalariform group anomalies are corresponding well to the medium and strong earthquake around.Three over moderately strong earthquakes around Jin Second Well were predicted with this kind anomaly.
