摘要
初步的野外调查表明 ,2 0 0 1年 1 1月 1 4日青新交界 8.1级地震的地表破裂带位于昆仑山南麓 ,西端可能终止于布喀达坂峰 ,东端点距青藏公路以东 70km .主破裂带总长度可达 3 50km ,总体走向N80°～ 85°W .具明显的左旋水平走滑运动性质 ,最大左错量为 6m .宏观震中初步定在库赛湖东约 3 0km一带 ,震中区烈度定为Ⅺ度 .根据初定宏观震中的位置 。
Preparatory field investigation reveals that the surface deformation zone of the Qinghai Xinjiang M_S 8.1 earthquake on November 14,2001 distributes along the south foot of Kunlunshan mountains, and may terminate at the Bugedabanfeng as the western end while the eastern end is tracked down at the point 70 km east from the Qinghai Xizang Raod. The total length of the deformation zone reaches 350 km. The deformation shows clear strike slip feature and the maximum horizontal offset is found to be 6 m. It was temporarily determined that the macro epicenter is 30 km east from the Kusaihu lake, and the intensity in the macro epicenter is Ⅺ.It's suggested that the earthquake be named as Kusai hu earthquake.
