Lake Albano has a volcanic origin. It is located in the Quaternary volcanic district of the Colli Albani (Albani Hills) at approximately 20 Km from the metropolitan center of Rome. The volcanic edifice hosting the lake is characterized by gently inclined outer flanks and steep slopes in correspondence with the internal walls of the crater. Here is where much evidence is found of slope failures producing landslides. The presence of numerous dwellings and of recreational activities along the internal slopes of the crater, and in particular along the edge and the lake coastline, make the area of potentially high risk, not only because of the inner intense slope instability, but also because of possible secondary effects due to tsunamis waves that might be generated by the impact of sliding...
