Lunar-solar tidal deformation processes and seismoacoustic emission in the geo-environment volume.

The article presents a study which investigates the correlation between the lunar-solar tidal deformation processes and seismoacoustic response of the geo-environment. Modified Coulomb-Mohr equation was used for the approximation of the brittle rocks and harmonic analysis of the seismic acoustic emission (SAE) time variations and tidal increments of the gravity force was conducted to distinguish the dominating periods in the spectra of the processes. Tidal waves were separated and its dynamics were analyzed. The study founds that lunar-solar tidal deformation processes have influenced the appearance of diurnal and semidiurnal periods in the time variations of the SAE at large depths because variations in the external influence on the geo-environment are related to the Earth's tides.
