Daning County is located at the southern end of Lüliang Mountain, Shanxi Province, with unique topographic and geomorphic characteristics of the loess plateau. The investigation of geological hazards was conducted in the area to determine the distribution, causes, and hidden dangers of disasters. Through the application of the relevant principles of geomorphology and remote sensing image interpretation, two large-sized and two medium-sized landslide bodies were detected and confirmed in the 0.3 km² (575 m×526 m) range of the two banks of the Yiting River. The characteristics of the four landslide bodies and their surrounding landform, as well as the change in the direction of the river course, are analyzed. We propose the following:(1) The four landslide bodies were formed in different geological periods. (2) One landslide body was obviously affected by a fault. (3) The three other landslide bodies were formed over a long period of time under the dynamic action of "gravitational collapse" and river flow direction. (4) The stress of three M_S8.0 earthquakes, i.e., the Hongdong and Linfen earthquakes (60 km from the area) and the Huaxian earthquake (more than 230 km from the area), aggravated the occurrence of the landslides. (5) Future studies should consider the possibility that landslides are accelerated by unconventional external conditions, such as heavy rainfall or earthquake stress.
