A slow and complex landslide process in the Southern Apennines (Italy)

The paper presents the phenomenological interpretation of the failure mechanism involving an active and complex landslide process within the Pisciolo hill-slope (Southern Apennines, Italy). The sliding process interacts with important infrastructures that in the last decade have undergone recurrent damage, prompting a comprehensive investigation and monitoring of the slope features and processes. Based on the study of all the investigation data, the interpretation of the failure mechanism has required the creation of the geological and the geotechnical model of the slope along with the reconstruction of the slope history. The case is representative of the slow evolution of landsliding typically occurring in chain areas where the outcropping clayey soils are extensively disturbed and fissured as result of intense long-lasting tectonics.
