Abstract：On the basis of detail geological investigations of the surface rupture zone caused by Wenchuan Ms8.0 earthquake by use of differential GPS measurement, the characteristics of spatial distribution of surface rupture zone are known that a 200 kmlong surface rupture was formed along the BeichuanYingxiu fault in the Wenchuan Ms8.0 earthquake. It also triggered the activity of the GuanxianJiangyou fault as indicated by an 75 kmlong surface rupture. The distribution of earthquake surface rupture shows that the initial rupture is mainly northeaststrike thrust with a little dextral slip and the subsequent rupture is a slip with the almost equal vertical and horizontal displacement.
