Convener Wataru Tanikawa  / Takeshi Iinuma  / Yuta Mitsui  / Hideki Mukoyoshi 
Scope Interdisciplinary discussions on the rheology of seismogenic faults and earthquake generation processes among the following specialists; (1) fault rocks and fault zones, (2) theoretical and numerical studies on earthquake dynamics, and (3) seismology and geodesy. Presentations on fault-zone drilling projects are also welcome. We encourage students and young scientists to present in oral sessions, and topics which introduce new concepts, observations and experiments in relation to understand earthquake dynamics.
