On January 7, 2025, an earthquake of magnitude MS6.8 struck Dingri County, Xizang Autonomous Region. In this paper, the near-field seismic wave field and instrumental intensity field were simulated using the strong ground motion simulation and prediction cloud platform of the Institute of Engineering Mechanics, China Earthquake Administration (CEA), combined with the kinematic seismic source model, the regional public velocity model and the digital elevation model. The simulated and measured instrumental seismic intensities are comparable at the stations of the National Seismic Intensity Rapid Reporting and Early Warning Project. The simulated high intensity zones are mainly distributed around the place of the surface projection fault, and the simulated instrumental seismic intensity field is basically the same as the survey seismic intensity field. On the basis, the earthquake damage to typical buildings (mainly earth/stone and wood structures) and casualties was evaluated and the evaluation results were also comparable to the actual data.
