Аннотация

Observational results of wideband geophysical processes (acoustic, seismic, strain-baric) obtained by means of the Kotelnikov IRE laser strainmeters and the IKIR geo-acoustic measuring complex have been presented. Seismic and strain-baric measurements in seismic energy active zone (Kamchatka, w. Paratunka) have been performed by the on-ground strainmeter built on the three-mirror laser interferometer scheme with the 32 m long measuring arm. For observations in aseismic zones (Moscow Region), laser strainmeters of lengths from 10 m up to 400 m on the underground beam waveguide in Fryazino, and lengths from 5 m up to 90 m in geophysical gallery in Obninsk have been used. Measurement have been carried out by instruments based both non-equal arms and equal arms (symmetric) Michelson interferometers. The description and features of the IKIR geo-acoustic measuring complex for investigations of geo-acoustic emission at different stages of seismic event preparations have been discussed. The examples of synchronous recordings of seismic-acoustic and strain-baric processes in Kamchatka and Moscow Region are shown and obtained results of parallel data analysis are presented. The carried out investigations show the ability of the developed methods for extracting global geophysical phenomena connected with strong earthquake M>7 preparing, powerful tropical cyclones (hurricanes, typhoons), tsunami, and wide range extraterrestrial environment events.
