The investigation on damages to frozen soil sites during the West Kunlun Mountains Passearthquake with Ms 8.1 in 2001 shows that the frozen soil in the seismic area is composedmainly of moraine, alluvial deposit, diluvial deposit and lacustrine deposit with the depthvarying greatly along the earthquake rupture zone. The deformation and rupture of frozen soilsites are mainly in the form of coseismic fracture zones caused by tectonic motion and fissures,liquefaction, seismic subsidence and collapse resulting from ground motion. The earthquakefracture zones on the surface are main brittle deformations, which, under the effect of sinistralstrike-slip movement, are represented by shear fissures, tensional cracks and compressivebulges. The distribution and configuration patterns of deformation and rupture such asfissures, liquefaction, seismic subsidence and landslides are all related to the ambient rock andsoil conditions of the earthquake area. The distribution of earthquake damage is characterizedby large-scale rupture zones, rapid intensity attenuation along the Qinghai-Xizang (Tibet)Highway, where buildings distribute and predominant effect of rock and soil conditions.
