Deformation and acoustic precursors of earthquakes

An increase in the intensity of high-frequency geoacoustic emission in near-surface sedimentary rocks during the final stage of earthquake preparation at a significant distance from their epicenters is caused by an increase in local stresses [13]. Variations in the stresses related to the effect men...

Description
Summary:	An increase in the intensity of high-frequency geoacoustic emission in near-surface sedimentary rocks during the final stage of earthquake preparation at a significant distance from their epicenters is caused by an increase in local stresses [13]. Variations in the stresses related to the effect mentioned above have not yet been studied. In the present paper, we consider peculiarities of local deformation at the final stage of the preparation of remote seismic events to study the mechanisms of geoacoustic noise generation in the kilohertz frequency range.
