MONITORING OF SEDIMENTARY ROCK GEOACOUSTIC EMISSION BY A LASER STRAINMETER-INTERFEROMETER AND BY A THREE-COMPONENT PIEZOELECTRICAL SEISMOMETER

Abstract

The results of complex geodeformation observations in Kamchatka are presented. A laser strainmeter-interferometer (developed at IKIR FEB RAS) and a three-component piezoelectrical seismometer, constructed by ZAO “Geoakustica” and provided by IMGiG FEB RAS within a joint research, were used as the registering systems. Signals, received simultaneously by different registration systems, were analyzed. Seismic signals from earthquakes, pulses with the frequency up to 100 Hz and higher-frequency geoacoustic signals, which had been registered by a system of spaced hydrophones at IKIR FEB RAS before, were detected.
