The general objective of VIGIMONT is to develop a new service within two existing early warning platforms, by adding modules dedicated to real-time debris-flow and landslide dynamic vigilance for safety authorities in mountain areas. Indeed, with the deployment of meteorological radars, the occurrence of debris flows and landslides induced by meteorological events will be analysed, based on antecedent precipitations quantification and event rainfalls definition. It will permit to determine critical rainfall thresholds for events occurrences, allowing events detection and mapping. A multi-scale approach is proposed by considering both the regional and the local (municipality) scales, with the development of services for end-users acting at these two scales. Phenomena addressed here are focussed on some typologies of movements: it concerns shallow landslides, deep seated landslides and debris flows.
