TEMPORAL VARIATIONS IN GEOPHYSICAL FIELDS AND EARTHQUAKE FORECASTING ISSUES
https://doi.org/10.5800/GT-2015-6-1-0172
Abstract
Results of the experimental long-term monitoring programme are presented. It is aimed at studying natural geophysical fields located above the gas deposit in the zone impacted by the active regional fault, and its objectives are to reveal how such fields are changing with time and to establish a relationship between the temporal changes and seismicity. According to the database it determines several typical indicators of variations in the geophysical fields, which take place only above the gas deposit. It is concluded that periods, when natural geophysical fields located above the gas deposit are unstable, are preceding the final phase of preparation of seismic events.
