Predisposing Factors for Shallow Landslides in Alpine and Hilly/Apennines Environments: A Case Study from Piemonte, Italy

Landslides are the most common natural hazard in Piemonte region (northwestern Italy). This study is focused on shallow landslides caused by sliding of surficial detrital-colluvial cover rainfall and characterized a sudden fast evolution. investigates landslide events compared with variables considered as main predisposing qualitative factors (lithology, pedology land use) to obtain zonation susceptibility GIS environment. Additionally, wildfire occurrence also evaluated further factor for initiation. The resulting map shows strong correlation between first three occurrence, while it negligible, or very localized, relationship occurrence. Through intersection data points, homogeneous zones obtained; each identified zone uniform lithological, soil-type, land-use characteristics. density computed zone, four-range map. can be used define evaluate linked civil protection regional planning purposes.
