This paper will demonstrate how municipal governments can manage landslides with the use of inspection records and spatial data. Specifically, the study applies a multivariate analysis method, quantification theory type 2, to statistically evaluate the risk of slope failures caused by geomorphological factors. In addition, it is clear the the significance of data update and selection of factors for accurate analysis. The scores from these analytical results reflect the risk of the slopes sampled in the analysis. By applying this mehod, we identify the areas prone to landslides and prioritize to the area in consideration of damage to buildings and roads. The results of this study will specify and predict areas prone to collapse for warning and evacuation procedures.
