| 摘 要： | 总结了１９９５年７月２２日永登５．８级地震前的地壳形变异常特征，研究了跨断层形变异常及其与地震的对应关系，地震发生在隆起区边缘的形变高梯度带上，有明显的地形变前兆，说明大面积地形变与断层形变观测相结合对一些较大地震作出预报是可行的

| Abstract: | The anomaly characteristics of the crustal deformation before Yongdeng earthquake ( M s= 5.8 ) are summarized, and the corresponding relation between fault deformation and earthquake is investigated.This earthquake occurs in the high gradient belt along the edge of the uplift region of vertical deformation and has clear earthquake precursor.It is showed that combining the fault deformation and large-scale crustal deformation to predict great earthquake is feasible. |

| Keywords: | crustal deformation fault displacement earthquake prediction Yongdeng earthquake. |
