- Аннотация: We propose a concept for a geodynamic model of East Asia, taking into account the mechanism of theinteraction between the stable part of the regional continental lithosphere and the active continentalmargin along the Kuril-Kamchatka and Japan island arcs. The concept involves upper mantleconvection combined with keyboard-block mechanism explaining seismic cycle patterns in the activecontinental margin and provides grounds to resolve the paradoxes of the present-day velocity fieldobserved by satellite geodesy methods. These paradoxes are associated with enormous variation in thevelocity field, such as sometimes contradict directions of surface motions in the adjacent portions of theearth’s surface. We propose a model that attribute the observed motion pattern to the superposition ofthe long-term subduction-driven convection regime beneath the continent causing the ocean-wardlithosphere extension and the shorter-term cyclic motion of seismogenic blocks with alternatingdirections. The model contributes to the development of the physically-based theoretical concepts ofmodern plate tectonics and eliminates the contradictions between the observed data and classical platetectonics in East Asia region.
