1984年11月21日晚7时许,青海省同仁县隆务镇西面的隆务西山,发生一起大型滑坡。滑坡从相对高180—200米的隆务西山中部向下滑动,并在山脚处剪出,滑坡总体积达180—200万立方米。滑坡使黄南中学后面的围墙倾倒,6间教工宿舍倒塌,球场破坏,在其前方直接威胁该校主教学楼及2,000多名师生员工生命财产的安全。受该滑坡的牵动,黄南中学东侧毗连的坡体失稳,斜坡的顶部及中前部出现裂缝,在其坡脚前缘处有个仓库的地面开裂、倾斜。这些变形迹象表明,另一个更大的滑坡正在酝酿发育之中。
At about 7 pm on November 21, 1984, a large landslide occurred along Longwu Xishan, west of Longwu Town, Tongren County, Qinghai Province. The landslide slides downward from the middle part of Longwu Xishan at a height of 180-200 meters and cuts off at the foot of the mountain. The landslide has a total volume of 1.8-200 million cubic meters. The landslide dumped the walls behind Huangnan High School, the collapse of 6 faculty dormitories and the destruction of the stadium, threatening the safety of the school’s teaching building and the lives and property of more than 2,000 teachers and students directly in front of it. Affected by the landslide, the slope adjacent to the eastern side of Huangnan Middle School became unstable. Cracks appeared at the top and middle of the slope. The ground with a warehouse at the leading edge of the slope began to crack and tilt. These deformation signs show that another larger landslide is brewing development.
