| Research Abstract |
To estimate fault specific earthquake scenarios due to their each tectonic circumstances for ground motion prediction, we developed a system to generate earthquake scenarios by estimating heterogeneous stress fields from geographical and geological information and cyclically applying dynamic rupture simulations. In the application to the Uemachi fault zone, we found that estimated heterogeneous stress distribution controls the rupture propagation on this fault system. The summation of slips of plural events seems to agree with the long-term average slip distribution model.
