    Abstract
  • In this paper, strain softening model is used to establish the modeling for Yushu MS7.1 earthquake. The results shows that Yushu MS7.1 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.
