| Outline of Final Research Achievements |
This project aimed to develop a statistical method to estimate the spatial distribution of slip of a large earthquake and to evaluate the spatial heterogeneity of frictional parameter. A uniqueness of the developed method is to use seismic activity data, which would contain physical information such as stress state in depth but has not been analyzed thoroughly. It was applied to the real aftershock sequences of several large events, in particular ones at a plate boundary. As a result of the analysis, inferred slip distributions are consistent with those estimated in previous studies. It is also revealed that the dependency of the frictional parameter upon depth is statistically significant.
