Based on remote sensing interpretation, geological investigation, trench excavation, and profile research, it is concluded that the linear characteristics of remote sensing images in the front of the Amuni Mountain are obvious, and there are suspected surface ruptures of approximately 30km in length, and faults of alluvial fans of different periods. With terraces, geological surveys revealed that there are seismic rupture relics such as fault ridges, fault grooves, seismic drum beams, and water system twists along the fault. There is a 120°-130° strike, a coseismic displacement of 2.3m, and a length of about 20km. The surface is broken. Based on the empirical statistical relationship between magnitude and surface rupture, and the empirical relationship between strike-slip fault and rupture length, it is calculated that the length of the surface rupture formed by the magnitude 6.8 earthquake is about 24.4km, and the coseismic displacement is 2.0m. The rupture length and coseismic displacement of this section Fully comply with the empirical statistical relationship and experience value. Comprehensive seismic geological survey results, seismic geological disasters and other data, it is confirmed that the macro epicenter is located in front of the Amuni Mountain in the northeast of North Hobson Lake, and its geographic coordinates are: 36.89°N, 96.61°E, which is 50km away from the micro epicenter. The seismogenic fault is the Amunicshan section of the northern margin of the Qaidam Basin. Since there are no permanent residents and no buildings (structures) in this area to inquire about and investigate the intensity of the earthquake impact, it is impossible to draw an earthquake intensity map.

In this paper, through remote sensing interpretation, geological investigation, exploration channel excavation, cross-sectional study and other research concluded that: in front of The Amunik Mountain remote sensing image linear features are obvious, there is a suspected length of about 30 km of surface rupture, fault fault fault in different periods of flood fan and terrace, geological survey found fault Along the development almost aqueducts, fault grooves, seismic drum beams, water system twists and other seismic rupture remains, there is a trend of 120 degrees -130 degrees, the same seismic displacement of 2.3m, about 20 km long surface rupture. Through the empirical statistical relationship between magnitude and surface rupture, the empirical relationship between slip fault and rupture length, the surface rupture length formed by the 6.8 magnitude earthquake is calculated to be about 24.4 km, and the same seismic displacement of 2.0m, the length of the rupture and the same seismic displacement are fully in line with the empirical statistical relationship and empirical value. Comprehensive seismic geological survey results, seismic geological disasters and other data, confirmed that the macro epicenter is located in the north-east of North Hobson Lake in front of The Amunik Mountain, its geographical coordinates are: 36.89 degrees N, 96.61 degrees E, with the micro-epicenter of 50 km deviation, the earthquake fracture is the northern edge of the Chaidamu Basin fracture amunik mountain section. Since there are no permanent residents in the area and no construction (structure) of the structure as a matter of inquiry and investigation of the intensity of the earthquake impact, it is not possible to draw a seismic intensity map.

Through remote sensing interpretation, geological investigation, trench excavation, profile analysis and other studies, this paper considers that the linear characteristics of remote sensing images in the front of amunik mountain are obvious, there are suspected surface rupture of about 30km long, alluvial fans and terraces with different fault dislocations. Geological investigation shows that along the fault developed fault scarps, fault grooves, seismic drum beams, water system twist and other seismic rupture traces There is a surface rupture with strike of 120 ° to 130 ° with coseismic displacement of 2.3m and a length of about 20km. According to the empirical statistical relationship between magnitude and surface rupture and the empirical relationship between strike slip fault and rupture length, the length of surface rupture caused by the Ms6.8 earthquake is about 24.4km, and the coseismic displacement is 2.0m. The rupture length and coseismic displacement of this segment fully conform to the empirical statistical relationship and empirical values. The macro epicenter is located in the front of amunik mountain in the northeast of North Hobson lake. Its geographical coordinates are 36.89 ° N and 96.61 ° e, which is 50km away from the micro epicenter. The seismogenic fault is the amunik mountain segment of the northern margin of Qaidam Basin. Because of the impermanence of residents and the lack of buildings (structures) in this area, it is impossible to draw a seismic intensity map.<br>
