TESTING THE METHOD FOR DETERMINING THE POTENTIAL OF SEISMOGENERATING ZONES BY GEOMAGNETIC DATA IN THE TERRITORY OF EASTERN KAZAKHSTAN

In certain territories of the East Kazakhstan region (Ust-Kamenogorsk, Semipalatinsk, the Ulba object, Zaisan), a method for calculating the seismic potential (maximum possible earthquake magnitude) was tested using geomagnetic data: the values of the geomagnetic Z-component calculated in the geocentric solar-magnetospheric coordinate system (GSM). Estimates of seismic potential based on geomagnetic data were compared with data on the potential of seismogenic zones in the territory of the East Kazakhstan region, obtained from seismological, geological and geophysical data and the results of interpretation of satellite images. Satisfactory agreement was obtained between the estimates by two different methods, which confirms the possibility of using an alternative method for estimating the seismic potential in regions with a deficit of information about the seismic regime (possibly, being at present in the regime of temporary seismic calm).
