On the basis of new ideas about the geological environment, a degassing model of the seismic process controlled by planetary hydrogen degassing was substantiated. Models of crustal seismic acts and DfSE are proposed. For the lithosphere, these are rapid movements along the boundary structures, for the deep-focus seismic events (DfSE) - an «explosive» release of hydrogen as embedding atoms, causing deformation of the hydrogen sublattice. The driving forces of the wave seismic process in the lithosphere, which is extremely energy-saturated in elastic energy, are the floating deformation waves of a diffusive nature, activated by continuously ascending hydrogen flows, providing a self-sustaining seismic process. The trigger action of hydrogen fluxes on the parameters of boundary structures is realized, which control slow (background mode) or fast movements of the elements of the medium relative to each other (weak events - in the background mode). Hydrogen activation of boundary structures translates the process of movement of the elements of the medium relative to each other into a barrier-free process with features of superplasticity. Manifestations of the strongest and mega events occur with additional activation of boundary structures by hydrogen flow due to local activation in the upper mantle of Vadkovsky›s «seismic nails». The continuous upward flow of hydrogen ensures the seismic interaction of processes in the upper mantle and lithosphere and controls the self-sustained seismic process in a wide range of depths.
