The analysis of mechanic-electromagnetic effects of the Earth’s crust made it possible to distinguish the relation of rock induced polarization with its deformation. On the basis of these relations, their generalized description is made. It is shown that, although the Earth’s crust is an energy-saturated structure in a critical state, but owing to electromagnetic properties, it is not a medium in which electromagnetic oscillations can be generated in the low-frequency region. At the same time, the Earth’s crust is favourable environment for the occurrences of seismo-acoustic oscillations. It is shown that the mechanisms of mechanic-electromagnetic transformations of the crust generate electromagnetic waves accompanying seismic-acoustic disturbances. Examples of these waves manifestations in electric currents and in electromagnetic radiation are given.
Key words: seismo-electromagnetism / electrodynamics of the lithosphere / electromagnetic manifestation of earthquakes / electromagnetic waves accompanying deformation / Earth’s natural electromagnetic field / electromagnetic radiation of the lithosphere
