wenzhang>In order to analyze the effect of Wenchuan Mwenzhang>_S8.0 earthquake on the seismic activity of surrounding faults, the authors calculate the dynamic changes of Coulomb stress caused by the Wenchuan Mwenzhang>_S8.0 earthquake with a Burgers viscous relaxation model. Simulation result shows significant increase of Coulomb stress on four majors fault segments. Furthermore,wenzhang> the effect of the postseismic relaxation is nearly equal to that caused by the Wenchuan earthquake itself. This is a strong evidence that the postseismic relaxation is critically important so it should not be neglected on evaluating the effects of strong earthquake.
