Outline
To simulate the impact of terrain on co-seismic deformation, this paper established three different terrain models. The results show that compared with flat terrain, convex terrain reduces the amount of horizontal displacement, while concave terrain significantly increases the amount of horizontal displacement. The terrain difference in the epicentral area of the 2024 Wushi, Xinjiang MW7.0 earthquake is significant, and the impact of the real terrain on the co-seismic deformation of this earthquake is not yet clear. This paper uses the spectral element method to simulate the co-seismic deformation of the Wushi earthquake and compares it with the co-seismic displacement field of D-InSAR. The results indicate that the impact of terrain factors on co-seismic deformation can reach 8.5%, 26.9%, and 6.8% in the E, N, and U directions, respectively.
