| Outline of Final Research Achievements |
We successfully explained the diversity of dynamic earthquake rupture process by
the single framework with heat, fluid pressure and dilatancy. We employed only two nondimensional parameters to understand such diversity. In particular, it is significantly important that both the accleration and the spontaneous slip cessation can be modeled by the single framework and we found the boundary between these behaviors analytically on the nondimensional parameter space. In addition, our analysis is also shown to be applicable to behavior of some kinds of chemical reaction systems. Our initial aim that we should obtain the analytical solutions applicable not only to seismological problem, but also to that of another field of physics or chemistry is clearly achieved.
