ANALYSIS OF TEMPORAL AND FREQUENCY CHARACTERISTICS OF SIMULTANEOUS GEODEFORMATION SIGNALS REGISTERED AT “KARYMSHINA” SITE

Abstract

Simultaneous geodeformational observations have been carried out from 2016 to the present time at “Karymshina” site on Kamchatka. A laser deformograph-interferometer and a three-component seismoacoustic receiver were installed to conduct these observations. Earlier it was revealed that a large number of signals were registered in rocks during deformation disturbances. In this work, we present the analysis results of the registered signals. Signal frequency response (magnitude and phase) was studied, and constant spectral components were identified.
