NEW EXPLANATORY VARIABLES TO IMPROVE LANDSLIDE SUSCEPTIBILITY MAPPING: TESTING THE EFFECTIVENESS OF SOIL SEALING INFORMATION AND MULTI-CRITERIA GEOLOGICAL PARAMETERIZATION

Landslide susceptibility maps (LSM) define the spatial probability of landslide occurrence based on the spatial distribution of predisposing factors. In this work, a LSM is produced for Norther Tuscany (3100 km2) with a Random Forest algorithm. The element of novelty is the use, besides 15 state-ofthe-art parameters, of some newly proposed parameters
