First, we chose 7 strong earthquake stations in which epicenter distance is less than 80km. The simulated results showed that, the timehistories records of high amplitude acceleration section are similar between observed values and synthetic values. Synthetic PGA is fitting better with observed PGA at the whole stations while synthetic PGA is a bit smaller than observed PGA in complicated terrain regions. This may be caused by terrains and site conditions in this area. The old Hanyuan county town far away from the epicenter suffered serious damage during Wenchuan earthquake. It is the only abnormal intensity VIII region in intensity VI region. Based on the Hanyuan strong motion investigation, the damage situation was introduced, and the data on strong ground motion and soil site conditions were collected. We chose 3 stations near the Hanyuan county for studying the characteristic of abnormal intensity region. The Hanyuan county town is far away from the epicenter suffered serious damage probable caused by complex source rupture process characteristic, the propagation medium, field environment and topographic effects. At last, we also discussed the principles of how to choose small aftershocks as green function. Because the source rupture progress of Wenchuan earthquake is too complicated, simulation results still have room for improvement.
