Since the targets of dynamics in mobile belts range from orogeny and the formation of large-scale faults which occur for several hundreds to thousands years to seismic and volcanic activities which occur during a lifetime of human being, the integration of geophysics, geology and geomorphology is necessary to reveal the essence. In order to reveal dynamics in mobile belts, it is required that the temporal and spatial development of stress field due to plate movement and rheological properties must be clarified. However, not only stress in the crust has not been known, but also the rheological properties characterized by elasto-visco-plastic materials, are very complex, which depend on the time scale and stress and temperature. Further, since the properties are greatly affected by fluids and reaction via fluids, petrological and geochemical approaches are also important for the clarification. Since changes in seismic activities and large-scale crustal movement have been occurring in the whole Japanese islands due to large changes of stress and strain fields since the great Tohoku-oki earthquake, the present time is best timing to work on these researches on dynamics in mobile belts. This session welcomes presentations from observational, experimental and modeling researches of different disciplines which aim at revealing the nature of dynamics in mobile belts, such as seismology, geodesy, tectonic geomorphology, structural geology, petrology, geofluids, etc.
