ABSTRACT

Rainfall-induced slope instabilities later propagating as flow-like phenomena are widespread all over the World and, generally, cause catastrophic consequences in urbanised areas due to their imperceptible pre-monitory signals, long run-out distances, high velocities and huge mobilised volumes (Sorbino et al. 2010). Features of slope instabilities/flow-like phenomena depend on predisposing factors as well as on initial and boundary conditions. Therefore, carrying out susceptibility and hazard analyses of slope instabilities/flow-like phenomena that might occur in a defined geological context first requires the definition of a deepen cognitive framework embracing the physical processes leading to either triggering or propagation stage (Corominas et al. 2014).
