利用地下流体观测井水位预测海南及邻区中强震发生时间

Prediction of the occurrence time of the moderate and strong earthquakes in Hainan and its adjacent areas by using the water level of underground fluid observation wells

利用海南地下流体观测井水位资料,选择适合长期、中短期地震异常提取方法,对海南及邻区M 4.0以上地震发生前水位异常进行分析,依据统计资料,提出预测海南及邻区中强震发生时间的指标与方法。

Based on the water level data of underground fluid observation wells in Hainan, a suitable method for extracting long-term, medium-term and short-term seismic anomalies is selected. The water level anomalies before M 4.0 earthquakes in Hainan and its adjacent areas are analyzed. According to the statistical data, the indexes and methods for predicting the occurrence time of moderate and strong earthquakes in Hainan and its adjacent areas are put forward.
