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 of crust and mantle by both passive and controlled source have successfully provided plenty of new information on their structural, mechanical, rheological and thermal properties that have presumably strong controls on tectonic activities in the overriding plate including faulting, seismicity and crustal deformation in various timescales. Our goal of this session is to advance the understanding of overriding plate deformation in various timescales based on state-of-the-art results of observational, experimental 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, exploration geophysics, geodesy, tectonic geomorphology, physical geology, petrology, geochemistry, geochronology, rheology and numerical/analogue modeling on deformation processes associated with plate subduction processes and related feedbacks.
