Abstract
The work is devoted to modeling and studying geodynamic processes occurring in the vicinity of focal zones of the strongest (M ≥ 8) subduction earthquakes at different stages of the seismic cycle based on satellite geodesy data. The processes of preparation and implementation of a number of powerful events that occurred in the Kuril–Kamchatka, Chilean, Japanese, and Aleutian subduction zones at the beginning of the 21st century were studied. Clear spatial relationships have been identified between geodynamic processes occurring at different stages of the seismic cycle. It is shown that structural inhomogeneities of the geoenvironment have a direct impact on the processes of accumulation and release of elastic stresses.
