In the context of slope instability phenomena, the detachment of blocks from steep walls account for 40% of landslides occurences in Alpine areas (Cooco,1991).
This phenomenon, also known as rockfall, occours in densely populated area such as the Italian Alps, where the hazard is quite high due to the presence of several buildings and house.
We have chosen to assess the risk posed by potential rockfalls in an area hosting a small industrial complex close to a steep limestone slope. To this aim, a comprehensive set o geological, geomorphological and geomechanical surveys were conducted both in detachment and transit zones.
The study area is located in the Carnic Alps, in proximity of a small stream - torrent vajont - at a height of 800-1300 m.
