Gravitational slope failures are common phenomena involving all rock slopes, at various scales. It is widely accepted that different factors exert an influence on those gravitational process. Among these, structural heterogeneities (inherited from the geological history of the massif) and alteration/weathering process are of first order....

The first erosional front of the south‐eastern Alps has been affected by several deep‐seated landslides. The movements affected a Jurassic limestone sequence underlain by an upper Trias unit (Keuper) mainly composed of marl and clays. Horst‐ and graben‐like structures, newly formed gravitational faults, outflow and other field evidence suggest...

Initial topography and inherited structural discontinuities are known to play a dominant role in rock slope stability. Previous 2-D physical modeling results demonstrated that even if few preexisting fractures are activated/propagated during gravitational failure all of those heterogeneities had a great influence on mobilized volume and its...
