FIELD: physics; geophysics.
SUBSTANCE: invention relates to geophysics and is intended for predicting earthquakes from change in the stress pattern in rocks in the area of the presumed centre based on anomalies of variation of the geomagnetic field. The method comprises measuring magnetic field variations at two stations - base station and working station; performing magnetotelluric sounding at the base station and the area of the second station; based on the results, selecting places for installing the second station according to the intensity of geoelectric properties of the section with the first (base) station, for example according to maximum correlation of magnetotelluric sounding graphs; detecting variations of the geomagnetic field at both stations (δT1 and δT2); calculating the difference in variations (Δ12(t)=δT1(t)-δT2(t); selecting variation anomalies, e.g. exceeding the difference Δ12≥kσΔ, where k=1,…,3, σΔ is the mean-square value excluding anomalous values, from which intensity of geodynamic processes are determined at the second station.
EFFECT: high reliability.
