The work is aimed at revealing a possible connection between seismic activity and cosmic-ray muon fuxes capable of penetrating into the Earth’s crust and generating a nuclear electromagnetic cascade in a tense seismically active medium, leading to the formation of microcracks, the opening of which is accompanied by the generation of acoustic and, under certain conditions, seismic energy as predicted by Tsarev and Chechin (Atmospheric muons and high-frequency seismic noise. In: Preprint of the FIAN, vol 179, 1988). The data of the underground installation (in a well at a depth of 52 m) for monitoring geoacoustic signals correlated in time with the fow of high-energy cosmic-ray muons generated in extensive atmospheric showers implemented on the basis of the experimental complex “ATHLET” in the Tien Shan High-Altitude Scientifc Station of the Physical Institute of the Russian Academy of Sciences were used. It is found that the daily number of acoustic pulses increases signifcantly before and during appreciable regional earthquakes. The most pronounced pulsed emissions of acoustic energy, correlated in time with the fow of high-energy cosmic-ray muons generated in extensive atmospheric showers, are followed by an increasing seismic activity in the region, that support idea that penetrating into Earth’s crust the fux of cosmic-ray muons may become a “trigger” of earthquake.
