Two methodologies for landslide susceptibility mapping in a Geographical Information System (GIS) environment are here presented. Camaldoli hill, the most prominent peak of the Phlegrean district (458 m a.s.l.), was selected for the model implementation. To this aim, bi- and multivariate approaches were adopted, considering seven possible factors predisposing to landslide occurrence (geology, slope, aspect, land cover, distance to streams, rocky scarps and distance to roads). The susceptibility maps produced with the two methods were then compared and critically evaluated using validation datasets (Receiver Operating Characteristic - ROC curves).
