This study conducted terrain analysis and remote sensing image interpretation to determine the distributions of historical and potential landslides in Shang-an Village and elucidate the characteristics of landslide development within the area. Using the discrete element method, we constructed a digital model of the study area in order to explore the landslide movement processes and determine the scope of influence with regard to deposition. The scope of influence was then used to perform hazard zoning in the creation of a landslide hazard map for use as a reference in future land planning and disaster prevention. Our results revealed 13 potential landslide masses in the study area, 92% of which are on unstable slopes with limited landslide activity. These areas should be the focus of future monitoring and remediation projects. Direct impact from falling rock is the main concern in the area roughly 50 m around the sliding masses in the source areas of the study region and approximately 30 m around the creek beds upstream. In contrast, being buried by debris flow is the concern in the lowland areas roughly 30 m from creek channels in the middle and lower reaches.
