- Abstract
The Earth is a powerful heat generator, and endogenous heat is the main and most constant factor controlling the changing intraterrestrial state of matter and the transport of molten deep-set material to the surface. Fluids (melts and gases) are transported through the global endo-drainage system (GEDS): a hydraulically united, high-pressurised megastructure with external parts represented by the subcrustal asthenolayer. In various parts of the subcrustal asthenolayer of GEDS, heating centers, where volumetric gas–fluid anomalies of deep and metamorphogenic genesis are formed and with which the mechanisms of preparation of strong earthquakes are associated, volumetric gas–fluid bodies of endo- and metamorphic origin appear periodically. Rapidly growing short-lived extension structures appear near the surface at the final stage of preparation for seismic catastrophes. They are a near-surface reflection of gas–fluid domes that are formed in the asthenolayer under the future hypocenter. The ability of deformation impulses–replicas to migrate after an earthquake along the GEDS is shown. The successive chain of deformation impulses on the long-period deformogram indicates that they belong to a single thermal process of global coverage. Based on the above geological and geophysical reconstructions and with allowance for the numerous catastrophes that were noted in thermally particularly "sensitive" near-surface media, there is reason to believe that an increase in the heating of the outer parts of the Earth and an increase in the level of seismicity occur due to the deep-set heat sources of the planet.
