| Abstract: | Based on the finite-element method of near-field wave motion, we present an explicit parallel finite-element method to simulate the dynamic rupture of 3D earthquake fault according to the frictional model. The formulation of different type of the node in the fault has been obtained. The rupture and slip process of the fault, the strong ground motion and the surface rupture can be simulated by this method. |
