Combining multi-typologies landslide susceptibility maps: a case study for the Visso area (central Italy)

The research proposes a simple but geomorphologically adequate method to produce combined landslide susceptibility map. In fact, in logic of real use, offering type-specific maps land use planners and administration could be not successful solution. On the other hand, grouping more types landslides misleading for model calibration considering that relationships between slope failures geo-environmental predictors should conveyed by abundance each type resulting specific diagnostic typology. this test, after having produced independent models flow, slide complex exploiting MARS (Multivariate Adaptive Regression Splines) set variables, map was obtained combining scores three source maps. finally validated with new unknown archive, showing very good performances.
