| Abstract: | Through analyzing the anomaly of Ganlin,Wusheng and Gaofengtou mobile short leveling in Yishu fault zone and surrounding NW strike faults and discussing the anomaly mechanism,we think that the three anomalyies are likely caused by crustal stress increasing in this area before and after Wenchuan earthquake. |

| Keywords: | Yishu fault zone cross-fault deformation mobile short leveling anomaly crustal stress |
