FIELD: geophysics.
SUBSTANCE: invention relates to seismology and can be used to predict earthquakes. On the seismically active territory, performing the regime observations of the earth's crust or closely related geophysical fields deformations, such as the micro-seismic emission level. By the observations data processing on computer, finding the statistically significant anomalous components, which are as close as possible to their amplitudes theoretical distribution around the proposed epicenter. Determining the expected earthquake epicenter and its source occurrence depth. From observations determining the earthquake preparation zone radius as the distance from the epicenter, at which the predictive anomalies significantly exceed their detection statistical error. Taking into account of the expected earthquake source occurrence depth and radius of its preparation zone, determining the seismic energy current value enclosed in the emerging source for not less than two epochs. During this time determining the source seismic energy increment and rate of its accumulation. Determine the expected earthquake magnitude and the time remaining until the predicted earthquake.
EFFECT: medium-term prediction of earthquakes.
