| Abstract: | Utilizing the mobile cross fault short line leveling and short baseline measurement data for over 20 years at 32 sites in Sichuan Yunnan area, we made a preliminary analysis of the contemporary activities and the activity characteristics of the major active faults in this area before the Wenchuan earthquake. The result indicates that since the 1980s the major active faults in this area mostly have showed successional movement and the regional stress in Sichuan Yunnan area increased persistently for two years after 2006 before the Wenchuan earthquake,besides,the relatively strong compressional stress toward NW SE appeared in the mid south segment of Xianshuihe fault belt and the mid south segment of Longmenshan fault belt. |
