California (LLNL) and Disaster Prevention Research Institute, Kyoto University, Japan (DPRI) on rupture dynamics for crustal earthquakes, we carried out analyses of effects of several dynamic rupture parameters, such as stress drop, slip weakening distance and stress excess on fault rupture slip, slip velocity, and rupture velocity. In addition, we examined potential relationships between the assumed initial stress conditions, including asperities location, and rupture initiation and the final slip and slip velocity obtained from the spontaneous rupture modeling.
