【 摘 要 】

Indian Plate on the south, Eurasian Plate on the north, and the Northwest region of China have been squeezed together since the Himalayan tectonic movement, while many faults have been formed. The research was based on the study of direction of active faults lied at the Qinghai-Tibet Plateau, which were formed in the Neotectonics since the Late Pleistocene epoch, the distribution characteristic of the stress release in the crustal deformation and epicenter of the earthquake on the both side of the Aerjin fault, Qilian Orogenic Belt and Eastern Kunlun. The intersection region of NNW-striking faults and the NWW-striking faults was under the maximum tectonic compression, it showed the most complicated geometric configuration and the stressed concentration site, so it can easily result in an earthquake, and precautionary measures must be made in this region.
