- Аннотация: lt is the principal aim of this paper to bring an idea that a large family of the earthquake peculiarities, which are not incorporated into the framework of traditional models, is closely related to degasslng process of the Earth. We develop a new earthquake model, which shows the lithospheric substratum as a two-component two-phase system consisted ofa supersaturated solid solution and a gas emanating from it. There are so-called zones of transparency (clusters of gas phase), which grow and coagulate. Such zones arise because of the local connectedness of the intraporous space. The lower part of the transparency area is characterised by pore pressure deficiency, which is compensated by durability and elasticily of the solid matrix. On the other hand, the upper part of the area includes zones with redundant pore pressure. The material damage in ultimate deformation zones changes the configuration of the porous space. The gas is mlgrated into upper horizons that in turn magnifies porous overpressure and favours a further damage of the solid matrix. Degasslng process tums lithosphere into a distributed, seismic generator. Source of the seismic generator energy is potential gravlty energy of the undifferentiated lithospheric substance. We present percolation mechanism that provides direct transformation of potentia] gravity energy to energy of damage. Earthquake statistics and energy release are discussed, and the Gravitational Griffith Criterion is esLablished. Connection wilt self-organised criticality is also discussed.
