Electromagnetic Manifestation of Geodynamic Objects of Earth Crust.

Linkage is investigated between geologic structure of the bowers of the Earth and impulse electromagnetic radiation (EMR) at daytime surface of Earth. Comparison between transmittances of lithosphere-atmosphere boundary for acoustic oscillations and electromagnetic oscillations allows to conclude that the EMR is more informative. A mechanism is suggested of arising of acousto-electromagnetic radiation from Earth interior at brittle-plastic deformation as a result of relaxation of tectonic-origin mechanical stresses, Use of the mechanism permits to explain existence of stable correlation between local impulse EMR at daytime surface and active depth-fault structures. Based on comparison between characteristic propagation-length of radiation and seismic data about fault-formations depth of attenuation, conclusion is made about existence of seismically invisible traces of fault structures that extend to daytime surface.
