Abstract
The method of earthquake’s predictions are based on the correlation between geomagnetic quakes and the incoming minimum (or maximum) of tidal gravitational potential. The geomagnetic quake is defined as a jump of day mean value of geomagnetic field one minute standard deviation measured at least 2.5 times per second. The probability time window for the incoming earthquake or earthquakes is approximately ± 1 day for the tidal minimum and for the maximum- ± 2 days. The statistic evidence for reliability of the geomagnetic precursor is based on the distributions of the time difference between occurred and predicted earthquakes for the period January-June of 2012 for Dusheti region.
