Abstract(summary):

The physics of seismic process in subduction is discussed with the case study of Kamchatka region being considered. Seismic process is not attributed to either cracking or rupturing. Hydrogen degassing controls variations in voluminous-stress state of the geomedium and such parameters of boundary structures as amorphization, texturization, and destruction. Both rapid and slow dynamic processes are controlled by the medium structure and by the parameters of boundaries; these processes are induced by strain autowaves related to reversible structural transformations of the medium at ascending diffusion of hydrogen. Seismic processes are related to rapid or slow disturbance of accommodation of the medium elements relative to each other. Owing to the properties of boundaries, this process runs in a non-barrier manner and has superplasticity features. The monitoring methods for media with active inner energy sources are proposed. Difference equations of system state evolution are used; these equations are derived and corrected from the measurements of structurally sensitive parameters (saying in more precise, seismic wave velocities). Equation of system state evolution, being derived in these dimensions, reflects the effects of interaction between object and medium. As a result of the study, monitoring of phase state of the geomedium is proposed to predict small probability of the strongest earthquakes during the controlled period.
