Abstract
The results of synchronous geoacoustic and electromagnetic measurements at three boreholes located in the Petropavlovsk-Kamchatsky geodynamic survey area with considerably different electromagnetic environments are studied. It is shown that reliable detection of geoacoustic emission responses to natural electromagnetic radiation in the range of 0.01–1.0 kHz is possible if geophones are placed in sufficiently deep boreholes. The results demonstrate the fundamental possibilty of using natural super-low-frequency electromagnetic radiation to monitoring of stress–strain states of the geological environment.
