An M_S6.9 earthquake occurred in Menyuan County, Qinghai Province, on January 8th, 2022. The epicenter is located at the tectonic transform region of the Lenglongling fault and Tuoleshan fault along the Qilian-Haiyuan fault zone (37.77°N, 101.26°E) of the northeastern Tibetan Plateau. This paper introduced the typical earthquake disasters and characteristics of co-seismic surface ruptures. The results of field investigation after the earthquake showed that the main shock ruptured two obvious surface zones with the length up to 26 km, and the overall strike was directed along NWW. The rupture property is mainly sinistral strike-slip with thrusting slip by dipping to NE. The typical rupture landforms caused by fault dislocation mainly exhibit as en echelon combined of separation fractures, tension shear fractures, seismic bulges, and fault scarps. The surface rupture at the segment from Daohe to Liuhuanggou is the strongest, with large scale and good continuity, causing the most significant earthquake damage, and the scale of the surface rupture gradually decreases to the east and west ends. The main shock ruptured the ice surface of the Daohe and the Liuhuanggou, with typical deformation of a series of fractures and bulges as well as small scale of geological disasters, such as slope collapse and rolling stones formed along the river bank. Based on the comprehensive analysis of post-earthquake damage and surface rupture distribution, the region between Liuhuanggou and Daohe can be determined as the macro epicenter of the Menyuan M_S6.9 earthquake.
