英文摘要	Numerical simulation of the earthquake processes is a key method to carry out physical accurate earthquake forecast in the future,but today empirical method is used in earthquake prediction, which is seldom successful. in this paper,we use a unified rate-dependent frictional law to formulate two different frictional states, one is sticking, and the other is sliding. based on r-minimum, time integration method with static explicit is adopted in finite element analysis in order to make the result convergent in calculation. take the sumatra subduction zone as an example, where the major earthquake with m-m 9.3 occurred in 2004, the process of locking, unlocking, and sliding between the subduction plate and the overriding plate is simulated. the large-scale sudden sliding, which is regarded as an event. the earthquakes simulated by the model on the sumatra subduction zone have characteristics of quasi-cycle in time and migration in space. the earthquake ruptures propagate upward from bottom. moreover, the geometry of the subduction zone has much influence on the location of the large event.
