Аnnotation: The Earth is the powerful heat generator, and endogenous heat is the main factor controlling the itraterrestrial matter state changing and following transportation of molten deep-set material to the surface. Transportation of generated fluids (melts, gases) is carried out through the global endo-drainage system (GEDS) – a hydraucally united, high-pressurised megastructure with external parts represented by the subcrustal asthenolayer. In different parts of the subcrustal asthenolayer of the GEDS heating centers periodically appear that reflect volumetric gas-fluid bodies of endo- and metamorphic origin. Mechanisms of strong earthquakes preparation are associated with these bodies. At the final stage of strong seismic catastrophes preparation, rapidly growing short-term lived structures of extension appear near the surface. They reflect gas-fluid domes that develop in the asthenolayer under the future hypocenter. The ability of deformation impulse-replicas to travel along the GEDS after an earthquake is shown. The successive deformation impulses on a long-period deformogram indicate that they belong to a single thermal process of global scale. Based on geological and geophysical reconstructions and taking into account the numerous seismic catastrophes that are registered in near-surface thermally “sensitive” media, there is the reason to conclude that due to rising up of deep-set heat sources activity we meet an increasing heating of the outer parts of the Earth and accompanying high level of seismicity.
