Since the target of dynamics in mobile belts ranges from seismic and volcanic activities, which we can experience during our lifetime, to orogeny and formation of large-scale fault systems, which take place for more than several millions of years, the integration of geophysics, geomorphology and geology is necessary. In order to understand the dynamics in mobile belts from microscopic fracture and flow to macroscopic deformation, we must clarify the spatial and temporal development of stress fields due to plate motion and other tectonic causes and rheological properties of the materials that constitute mobile belts, by using observational, theoretical and experimental approaches. In addition to this, since the rheological properties are greatly affected by fluids in the crust and reactions via fluids, petrological and geochemical approaches are also important. After the 2011 great Tohoku-oki earthquake, we observe large scale changes in seismic activities and crustal movements. The present is the best timing to work on dynamics in mobile belts. This session welcomes presentations from different disciplines, such as seismology, geodesy, tectonic geomorphology, structural geology, petrology, geofluids, etc.
