The detection of the mechanisms that control the landslides of the flow-type is a fundamental issue in the risk analysis.

Abstract

The detection of the mechanisms that control the landslides of the flow-type is a fundamental issue in the risk analysis. This task is challenging when large areas are affected by landslides and related geotechnical datasets only refer to small portions of the analysed area. In such a case, a methodology based on a multi-scale approach can be profitably used. The present paper deals with the application of the above methodology to an area of the Campania region in southern Italy which is among the most at risk areas in Europe. Particularly, at small scale, preliminary insights on landslides mechanisms are obtained through the F-N curves. Then, referring to the medium scale, evaluations on the predisposing factors and triggering mechanisms are carried out through basic geological, geotechnical and hydrological analyses. Finally, the role played by the local geological and geotechnical features for the onset of different triggering mechanisms is assessed, at large scale, by using standard and advanced geotechnical analyses.
