Geophysical site characterization for a large landslide 3-D modeling

A 5 km2 area in the Liguria Region (Northern Italy) is subjected to a wide kinematic phenomenon. This site spans on a pliocenic glacial till and its body of widely assorted sediments had been reckoned as being a large relict landslide. The loose-soils' thickness here varies from few meters up to 90, before of reaching the complex of the local bedrock formations (argillites, sandstones, mudstones, ophiolites and diabases in pillows). The seasonal rain/snow falls on the overall watershed represent the main trigger actions on the soil body's movements. Moreover, the bedrock buried morphology layout knowledge is important for the prediction and prevention of the damage to both the buildings and the generic infrastructures widely settled on the site. In the following paper the Authors illustrate the details of the geophysical techniques which were used to study and assess this characterizing key aspect of the large landslide body.
