The geological environment of the earth’s crust is considered as a non-equilibrium active open system. It is shown that the rock is a favorable medium for the occurrence of seismic-acoustic oscillations and unfavorable for the occurrence of electromagnetic oscillations in the low-frequency region. It is shown that the analysis of known mechano-electromagnetic mechanisms, explaining the existence of electromagnetic radiation accompanying earthquakes, is deformation-induced dipole radiation, the intensity of which is determined by both the nature of the movements and the electrophysical properties of the rock. An analysis of two-dimensional histograms of crustal deformations and natural electromagnetic radiation made it possible to identify several clusters corresponding to stable conditions of mechano-electromagnetic transformations, which can be explained by the nature of mechano-electromagnetic properties of the rock in the deformation sites. A joint analysis of the catalog of earthquakes and electromagnetic radiation signals made it possible to isolate electromagnetic signals of lithospheric origin.
Keywords: seismoelectromagnetizm, crust electromagnetic radiation, natural electro-magnetic field of ELF-VLF range, seismic activity, rock electromagnetic and mechanic properties, lithosphere electrodynamics.
