Rock Slopes Hazard Analysis based on Traditional and Remote Geostructural Survey: Case Study Vernazza Coast Village (Cinque Terre National Park)

The present work has been developed in parallel to a multidisciplinary project carried out by a cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action), in order to start up a team of “volunteer crisis mappers” and to propose a methodology to collect and analyze multi-sensor data. The testing site of activities proposed for the project is the Cinque Terre National Park, registered in the World Heritage List since 1997, in particular the Vernazza village. This area has been strongly affected by the flood of 25th October 2011. In this case, the study focused on rock slopes stability analysis, based on an accurate geostructural survey, considering both the traditional method and the laser scanner acquisitions. Discontinuity orientations which lead to the isolation of blocks are basically derived from the elaboration of the point clouds.
