Scope Subduction processes such as accretion, back-arc-spreading, and arc-arc collisions have created overall architectures of the Japanese island arc through geologic time. Recent advances in seismic imaging by both passive and controlled source obtained onshore and offshore Japanese islands have successfully provided plenty of new informations on structural, mechanical, rheological and thermal properties of crust and upper mantle that have presumably strongly controls on active tectonics manifested by seismic activities, crustal deformation and other tectonic records in the overriding plate. Our goal in this session is to advance the understanding of overriding plate deformation in various timescales based on state-of-the-art results of observational and modeling studies encompassing both earthquake cycles and tectonic evolution of the Japanese island arc and other plate convergent margins. We welcome contributions from seismology, physical geology, geochemistry, tectonic geomorphology, and numerical and/or analogue geodynamic modeling on deformation processes associated with plate subduction processes and related feedbacks.
