摘要
///On May 12, 2008, Wenchuan earthquake 2008 occurred on the Longmenshan belt, which is located at the eastern margin of the Tibetan Plateau, rupturing the Beichuan-Yingxiu and Guanxian-Jiangyou faults. The authors apply Yabuki ＆ Matsu’ura’s inversion method to estimate the co-seismic slip distribution of this earthquake from GPS data. The whole fault model is divided into four sub-faults during the inversion. The results show that the slips caused by the great earthquake are characterized mainly by thrust motion near Yingxiu, the south segment of the Yingxiu-Beichuan fault the dextral components are apparently larger than thrust slips at the north segment of the fault. The estimations agree well with the results of geologic survey and the characteristics of rupturing.
