青海玉树M(下标 S)7.1地震发震过程的数值模拟

In this paper, strain softening model is used to establish the modeling for Yushu M(subscript S)7.1 earthquake. The results shows that Yushu M(subscript S)7.1 earthquake occurred as a combination of northward compressing of the Indian Plate and southeastward compressing of the Qinghai-Tibet Plateau. The stress drop, energy release amount, the magnitude of dislocation of fault, and earthquake recurrence intervals are given by the modeling. The modeling results show a good match with the geologic survey in the field.
