Areas of landslide occurrence in the Pyungchang area of Korea were determined from the interpretation of aerial photographs and subsequent field surveys. Landslide locations were randomly allocated for landslide susceptibility map generation (70%) and validation (30%) purposes. Maps relevant to landslide occurrence (topography, geology, soil, and forest cover) were assembled in a spatial database, from which 17 landslide-related factors were extracted. The relationships between the observed landslide locations and these factors were identified and quantified using the evidential belief function (EBF) model. Three relationships were calculated: disbelief (Dis), uncertainty (Unc), and belief (Bel). The most representative of the resulting susceptibility maps (the Bel map) was validated using the landslide data reserved for validation
