Strong Motion Simulation of the Weihe Basin in Wenchuan Earthquake

Seismic response of the Weihe basin generated by 5.12 Wenchuan earthquake is simulated by using the spectral-element method and parallel computing technique, considering 3D basin model incorporated with real topography. The wave propagation and the comparison of the synthetic and observed records are studied in detail in this paper. The result shows that appropriate source and detailed basin model and accurate numerical technique can simulate the wavefield and large basin ground motion well.
