摘要
The stress field and velocity field in Yushu region are analyzed. On this basis, the earthquake mechanism of magnitude MS7.1 Yushu earthquake 2010 is simulated by numerical method with strain softening model. The stress drop, energy release amount, the magnitude of dislocation of fault, and earthquake recurrence intervals are given by modeling. Comparison of the modeling results with the results of geologic survey in the field shows that they are in good agreement.
