问题似乎认为山海拔的增加或减少是一致的和统一的,它不是。印度与西藏板块会聚在NNE-SSW方向总体的意思是每年26至36毫米的速度。然而,大多数时候这收敛都是静态应变能,释放弹性回跳在罕见的地震。此外,珠穆朗玛峰是北部边界的碰撞区。大部分的变形和应变能吸收进一步南部一叠瓦构造复杂的浅角over-thrusts西藏的印度板块。如果过去尼泊尔地震的话,融合的垂直分量约三分之一。即每年约8 - 12毫米,其中我们可以假设至少3/4发生变形进一步南部。树叶最大意味着隆起在珠穆朗玛峰每年6 - 9毫米,有概率在现实中有点少。卫星测量数据没有进行足够长的时间让我们得到一个长期处理提升利率。也有复杂的因素:1。 For a mountain mass of such a size there is likely to be isostatic movement caused by slow buckling of the crust in relation to the 'soft' upper mantle. 2. Earthquakes can both raise and lower the mountain according to the geometry of motion. In the last earthquake Kathmandu rose by a metre, but Everest fell by several centimeters. There is no guarantee that the next quake will do the same. A quake further south in the Himalayas is likely to cause back-tilting (and hence lowering) of the Everest massif, whereas a quake with an epicenter close to Everest could raise it by several metres. 3. The summit is covered by a variable thickness of snow, typically from 1 to 4 metres, so there is a discrepancy between the height of the actual summit (with snow) and the bare rock.
