Stress geomechanics specifies how rocks respond to stress and provides essential information on understanding seismic behaviors. Thus, some outreach researches address the stress state in the crust or along plate boundaries through geophysical, geodetic, and/or hydrological approaches, especially after recently great earthquakes. Such studies have raised the importance on the stress analysis, including coseismic stress perturbation, fault and earthquake mechanism, and geodetic modeling for discussion on earthquake generation. The aim of this session is to bring together the multi-disciplinary studies on stress geomechanics, including but not limited, to inland/ocean drilling, borehole measurement, earthquake focal mechanism, and geomechanical model application. We focus our discussion not only on the observation in association with physical models, but also consider interdisciplinary cooperation.
