Abstract
The detailed analysis of physics of processes and phenomena that are in the basis of the geoacoustic emission and geoelectromagnetic emission (natural impulse electromagnetic field of the Earth -NIEMFE) methods in geodynamic studies was presented. We show that it is working closely inextricable complex of processes and phenomena, such as geomechanical regularities of deformations and fracturing of rocks and complex of processes (which are associated with microcracks) in geodynamic active and indicative zones – areas of most rocks unloading and most (most notable) geoacoustic emission and geoelectromagnetic emission effects, including, in particular, the influence on these areas the permanently effecting in the rock masses background (noise) elastic waves of wide frequency range – a phenomenon of singular geoacoustic emission and geoelectromagnetic emission energy “biasing” and in fact the very processes of cracking and opening/closing of different scale microcracks in rocks and accompanying them geoacoustic emission and geoelectromagnetic emission effects and phenomena which are direct generator of respective geoacoustic emission and geoelectromagnetic emission signals.
