Outline
In this paper, the stochastic finite-fault method is used to simulate the ground motion of the Wulong MS5.0 earthquake. The simulation results for four stations within 100 km of the epicenter showed that the simulated acceleration time histories, peak ground acceleration, and response spectra are generally consistent with the actual records. Some discrepancies were observed at individual stations due to the influence of model parameters and environmental noise. Simulations were performed for 323 grid points within 100 km of the epicenter, and the spatial distribution characteristics of the ground motion obtained were consistent with the intensity field survey data. This study provides data support for seismic fortification and risk assessment in the Chongqing region and has both theoretical and practical significance for mitigating earthquake disasters.
