ENERGY OF THE RELATIONSHIP BETWEEN VOLUMETRIC DEFORMATIONS AND SEISMICITY IN FAULT ZONES

Abstract

The results of comparative analysis of modern volumetric deformations and seismicity in fault zones of seismically active (Kopetdag, Kamchatka) and weakly seismic (South-East of Tatarstan) regions are presented. It is shown that there is an inverse relationship between the energy characteristics of deformation and seismological processes in space and time. It is concluded that the observed antiphase behavior of energy characteristics is due to the alternate realization of the volumetric and shear parts of the accumulated potential energy of the medium. It is suggested that the presence of more intense volumetric deformations of fault zones of platform, weakly seismic regions is due to a decrease in the share of realization of the shear component of deformation energy due to reduced seismic activity in these regions.
