| Outline of Final Research Achievements |
I developed a method to model and estimate the absolute stress field from earthquake focal mechanism solutions using a single parameter of pore fluid pressures, based on the Bayesian statistical inference. In this method we can obtain 6 components of a stress tensor, which enables us to evaluate temporal changes in various kinds of physical quantities following large events. Especially, it is important to estimate the absolute stress level, based on the temporal change in elastic strain energy. I also proposed a method to evaluate the estimation errors for a stress inversion method.
