Equation of generation of spontaneous electromagnetic signals in the system of lithosphere blocks

© Shuman V.N.

Nonlinear equation of generation of lithosphere electromagnetic signals, which describes uniformly different mechanisms of mechanical-electromagnetic transformation has been proposed on the base of generalization of the familiar theoretical approaches and qualitative ideas. Key element of consideration is phenomenological choice of form of nonlinear function setting the intensity of these transformations. Possibilities of remote propagation of relatively weak signals of radio-wave range within the Earth's crust to the distances, exceeding ten times the characteristic length of propagation are considered taking into account nonlinearity of equation. Special features of spatial localization of anomalies of intensity of spontaneous LEMS are being considered and their connection with the structure of deep geological objects based on the idea of "trapped waves" (generalized Relay waves, fading exponentially on both sides of division plane and canalized with it), which propagate along fault zones.
