| Abstract: | This paper discusses the instabilities in an earthquake process by means of nonlinear mechanics and establishes a relevant catastrophic model. It expounds the effect of the constitutive behaviours of fault belt and the selection of state variable in the catastrophic model on earthquake instablity and thus reveals the feasibility to research an earthquake phenomenon by catastrophic theory. |
