摘要
通过对晋1-1井22年水位观测资料进行系统清理,对距井区约330km范围一些中强震前的水位资料进行了细致分析。结果表明:晋1-1井地震异常以短临突变异常为主,异常时间多小于80d。根据大量的震例统计结果给出了地震前兆异常定量判别指标,当曲线阶升异常幅度大于30mm或阶降大于40mm时视为震兆异常。
In this paper,22 year water level data of Jin 1-1 well are processed and the relationship between water level anomalies and moderate earthquakes within 300 km of the well is studied.The result shows that the anomalies are mostly abrupt short-impending anomalies less than 80 days.Step-rising anomaly with amplitude of over 30mm and step-dropping anomaly with amplitude of over 40mm can be seen as seismic precursor.
