摘要
Based on analysis of strong motion records of Wenchuan Ms 8.0 earthquake on May 12, 2008, the authors compared and discussed the distribution characteristics of peak ground acceleration (PGA) and coseismic displacements to disclose the correlation between earthquake intensity distribution and surface rupture. The results show that the Wenchuan earthquake contained at least 4 times of rupture events during the whole process. The most important first two events corresponded respectively to ruptures occurred in the Yingxiu-Beichuan fault and the Beichuan-Nanba fault.
