Because plate collisions and sea-land changes for many times in the park, the area is a juncture for closing between Paleo-Asian Ocean and Tethys Ocean, and Qinghai-Tibet Plateau quickly uplifts as of the Pliocene, the park becomes the main area with stress relief and transition in the edge zone in the north of Qinghai-Tibet Plateau now and modern earthquake origin due to seismic effect resulting from resurgence of some deep faults. Finally, earthquake relics in the park are formed.
Strike-slip faulted zone in Mount Kunlun is the primary cause of earthquake in the park and earthquake relics, which is important active fault and seismic-tectonic zone in the north of Qinghai-Tibet Plateau and constitutes the boundary between Mount Kunlun active block and Hoh Xil active block. A 6.8-magnitude earthquake in Tuosuo Lake happened on March 24, 1971, a 7-magnitude earthquake in the east of Alake Lake on April 19, 1963, Ms a 7.5-magnitude earthquake in Huashixia Town on January 7, 1937 and a 7-magnitude earthquake in the west of Alake Lake on November 4, 1902 along the active fault of Mount Kunlun. On November 14, 2001, a violent earthquake at a magnitude of8.1 occurred to the active fault of Kusai Lake along the west of strike-slip fault of Mount Kunlun, which was called as Ms 8.1 magnitude earthquake in Mount Kunlun or Ms 8.1 magnitude earthquake in the west of Kunlun Mountain Pass with macroscopic epicenter near Kusai Lake and epicenter recorded by the instrument in Bukedaban. Ms 8.1 magnitude earthquake in Mount Kunlun resulted in 350～450 km earthquake rupture on the surface of the earth, penetrated and cut Qinghai-Tibet Railway, communication optical cable, construction road of Qinghai-Tibet Railway and other engineering facilities and caused snow slide in Mount Kunlun and leading to damage in Xidatan.
