| Outline of Final Research Achievements |
We performed numerical simulations of earthquake and SSE triggered by seismic waves. We assumed a revised Nagata frictional law which includes effects of normal stress changes. Shear or normal stress perturbations were applied to a circular asperity at some timing of earthquake cycle, earthquakes with high speed slip or SSE were triggered. In addition, we found that seismic wave can trigger earthquake or SSE at a patch where stable sliding occurs usually.
