摘要
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.
