| 摘 要： | 介绍了博洛科努断裂西北段阿拉山口至精河县城以南的古地震形变带的几何特征、形变方式和变形幅度，并讨论了最后一次地震事件的震级。认为该形变带为右旋走滑性质，最后一次地震事件的水平位移可能为２．５ ｍ ，垂直位移为０．９～１．８ ｍ ，震级估计为７．５～７．８ 级

| Abstract: | The Bolohkenu fault is an important tectonic zone.Its northwestern section between Alashankou and Southern Jinhe is a nearly 100 km long paleoearthquake deformation belt,the geometric character,deformation pattern and range of which are studied in this paper.And the magnitude of last event on it is discussed.It is thought that this deformation belt has a right lateral,strike slip feature, and has displaced by as much as about 2.5 m horizontally and 0.9~1.8 m vertically in the last event,and that the last event is estimated to has the magnitued of 7.5~7.8. |
