A NEW IDEA AND A NEW METHOD FOR EARTHQUAKE PREDICTION BY GROUNDWATER LEVEL

By different responses of well water level and by different methods, the inversion of aquifer stress for water level has been made, the anomalous information has been extracted and the corresponding earthquake probability has been given respectively.The analysis of time-space evolution and frequency of aquifer stress anomalies has been made, thus it is put forward that the Datong earthquake resulted from the regional stress field evolution, in this evolution process, the well aquifer stress anomalies showed regional characteristics in anomalous space distribution, stage characteristics in anomalous time distribution, transfer characteristics of anomalous time and space, and consistency of anomalies frequency and the epicenter.
