| 摘 要： | 通过对2003年9月27日发生在新疆友谊峰东北7．9级地震震前乌鲁木齐形变站垂直形变异常特征的分析，得出该台站垂直形变在地震临震前有明显的异常反映，地震前北天山中、西段地区4．9级以上地震活动较活跃，垂直形变运动速率加速上升，地震当日观测数据出现突跳现象。

| Abstract: | The anomalous characteristics of vertical deformation in Urumqi deformation station before Ms7.9 earthquake in eastnorthem of Youyifeng mountain on Sep. 27, 2003 are analyzed, the result shows, there are obvious imminent abnormities of vertical deformation, and before the earthquake, in middle and western region of northern Tianshan mountain, the activity of Ms ≥4.9 earthquakes is active, rate of vertical deformation accelerate, there are sudden jump phenomenon in the observational datum. |
