Geomorphological hazards and monitoring activity along the western rocky coast of the Portofino Promontory (Italy)

With the presence of predisposing factors relating to the structural lithology and geomorphology of the rocky slopes, the triggering causes of the gravitational movements are attributable to extreme heavy rainfall and to wave cutting, often with concomitant action on the part of both. The study offers a contribution to encourage concrete efforts to continue the monitoring of this area; the overall objective would entail the planning of general stabilization measures, or at least measures to reduce evident geomorphological risks, also taking into account the remarkable environmental value and qualities of this coastal sector.
