Abstract
Mitigating the risk due to shallow landslides and debris flows at a regional scale is challenging. Landslide Early Warning Systems (LEWS) aim at predicting the time and location of upcoming events. Usually LEWS use information on terrain susceptibility to determine the prone areas and rainfall observations to depict when an event can be triggered. The majority of LEWS employ pixel-based susceptibility maps, but some others use maps based on other terrain map units such as hydrological catchments...
