TXT-tool 4.039-4.1: Landslide Investigations and Risk Mitigation: The Sarno, Italy, Case
Recently, a number of catastrophic debris flows revealed the high risk in an extensive area of the Campania Region, Southern Italy. Following intense rainfall, on May 5th 1998, over 100 flow slides occurred on Pizzo d’Alvano mountain and hit the urban areas of Sarno and neighboring. The hills and mountains of this area are covered by air-fall pyroclastic soils deposited during volcanic eruptions occurred in the last tens of thousands years. In order to reduce the risk a lot of studies and investigations have been carried out and big and meaningful structural measures have been achieved, described in this paper.

Special thanks are directed to the technical staff of the Territorial Survey, i.e. engineers and geologists that during the emergency phases, the days after the events, and during the phases of the planning and construction of the protection works have collected and stored data, pictures, drawing here presented.
