Abstract
Summary
To locate critical facilities, for example, nuclear power facilities, seismically quiet territories are usually chosen. At the same time, in many continental regions the periods of recurrence of strong earthquakes can be hundreds or more years that results in a deficit of seismic information for assessment of a seismic potential of this region (maximal possible magnitude of earthquake - Mmax). We propose an alternative approach for estimation of a seismic potential, based on the use of values of geomagnetic Z-component estimated in the Geocentric Solar-Magnetosphere coordinate system (ZGSM). The scientific and methodological foundations of this approach and the regression relation for estimation of Mmax on the base of the ZGSM value were developed by us earlier [Khachikyan et al., 2012, IJG, doi: 10.4236/ijg.2012.35109], and in this report we give the coefficients of a relation for different regions with different type of tectonics: Alpine-Himalayan orogeny belt, San Andreas Fault, subduction areas in the South-East Asia, and for the most seismic region in the Northern Tien-Shan.
