EARTHQUAKE PREDICTION BASED ON THE HYDROGEODEFORMATION FIELD MONITORING DATA

The paper discusses further ways to improve the geodynamic informativity of the hydrogeodeformation field (HGD field) monitoring. New methods for efficient assessment of the stressstrain state of the geological environment and seismic hazard are proposed. There are described the methods of monitoring data processing, distinguishing of HGD cycles, and construction of «forecasting» contours along extremums of these cycles. It is revealed that responses of the HGD field to development of planetaryscale endogenic geodynamic processes of earthquake preparation (with M>7) are simultaneously manifested in all seismically active regions of Russia which are remote from each other. Such responses occur from one to three months prior to such seismic events. The mechanism of this phenomenon can be disputed. The authors support the «planetary pulsation» concept which is up for the most recent debates. As evidenced by the HGD field monitoring data, strong earthquakes are a consequence of this phenomenon
