The latest block activation of the earthcrust and seismic hazard in the Upper Amur region, the Far East of Russia

Abstract

The seismic hazard of the Upper Amur region is proposed to be determined using the volume of seismogeneration blocks, the area of seismic spots and the values of rate gradients of recent tectonic movements considering the dimension of gradient zones. The vlocks of probable earthquake chambers (PEC) which are marked by the obtained calculated magnitudes (M) and energy classes (K) of maximum probable earthquakes are intended to be distinguished on the map.
