珠穆朗玛峰位于欧亚板块和印度板块边缘的碰撞地带，地壳运动活跃，３０余年来，共进行３５次大规模的大地测量．根据这些大地测量成果对该地区的地壳运动进行了研究和探讨，认为珠峰地区地壳垂直运动在时间上和空间上都可能存在非平稳性，并发现在时间上的非平稳性与地震学家提出的地震活跃幕似有一定相关性；在空间上的非平稳性可能和地壳介质的非均匀性及地应力的非均匀吸收有关；珠峰地区的地壳水平运动以每年６～７ｃｍ速度向北东东方向运动，印度板块和青藏块体在冲撞边缘呈现明显的走滑运动趋势．
Everest is located in the collision zone between the Eurasian Plate and the Indian Plate. The crust is active. For more than 30 years, a total of 35 large-scale geodetic surveys have been conducted. Based on these geodetic results, the crustal movement in this area has been studied and discussed. It is considered that the vertical crustal movement in the Everest region may be non-stationary both in time and in space and found to be non-stationary in time. Seismologists Of the active seismic screen seems to be a certain correlation; in the spatial non-stationarity may be related to the heterogeneity of the crustal medium and the inhomogeneous absorption of geostress; crustal horizontal crustal movement at an annual rate of 6 ~ 7cm to the north east The eastward movement, the Indian plate and the Qinghai-Tibet block show obvious strike-slip tendency at the collision edge.
