ScopeStress geomechanics specifies how rocks respond to strain, fluid and heat that provide essential information on understanding seismic behaviors. Thus, some outreach researches address the stress state in the geological structures or along plate boundaries through geophysical, geodetic, geothermal and/or hydrological approaches, especially after recently great earthquakes. Such studies have raised the importance on the stress analysis, including stress evolution by seismic and volcanic activity, in-situ stress measurements, crust heterogeneity, and geodetic modeling for earthquake cycle. This session is to bring the multi-disciplinary studies together on stress geomechanics, including but not limited, to inland/ocean drilling, borehole measurement, focal mechanism of crustal and volcanic earthquakes, subsurface anisotropy analysis and geomechanical model applications. We focus our discussion not only on the observation in association with physical models, but also interdisciplinary cooperation in each research field.
