野外考察表明，2001年11月14日青藏高原昆仑山中段8.1级地震产生了一条近400米长的地表破裂带，沿北方昆仑山活动断裂带的左旋走滑沿着16.3米。其破裂长度和最大位移是迄今为止所报道的同震地表破裂带中最大的。地震产生的走滑运动和大的破裂长度表明，昆仑断层将其变形划分为西藏的东向挤压，以适应印度板块向欧亚板块的继续渗透。
Field investigations show that the surface wave magnitude (M-s) 8.1 Central Kunlun earthquake (Tibetan plateau) of 14 November 2001 produced a nearly 400-kilometer-long surface rupture zone, with as much as 16.3 meters of left-lateral strike-slip along the active Kunlun fault in northern Tibet. The rupture length and maximum displacement are the largest among the co-seismic surface rupture zones reported on so far. The strike-slip motion and the large rupture length generated by the earthquake indicate that the Kunlun fault partitions its deformation into an eastward extrusion of Tibet to accommodate the continuing penetration of the Indian plate into the Eurasian plate.
