Outline of Final Research Achievements

The purpose of this study is to examine a time-spacio change in paleo-stress and effective friction coefficient with seismic cycle. We conducted paleo-stress estimation, elastic wave velocity measurements and estimation of fluid temperature and pressure.
In the results, we obtained the horizontal compressional principal stress in the direction of plate convergence as expected. And the horizontal extensional principal stress was also detected generally. Effective friction coefficient is larger in former and smaller in latter, which corresponds larger fluid pressure in former than that in latter. The changes in paleo-stress and others can be explained by the stress switch associated with stress drop at the time of seismogenesis. Elastic properties at boundary faults and temperature and pressure of fluid indicate the high fluid pressure along the fault, which is coincident with the state before or at the time of seismogenesis.
