Abstract(s)

Rocky cliff coasts constitute approximately half of the world’s coastline and support human activities and diverse ecosystems but are prone to landslides, a key geomorphological process. This study assesses mass movement susceptibility along Safi's coast in Morocco by analyzing 297 mass movements using topographic, geological, and hydrological predisposing factors according to the information value model. The susceptibility model revealed that 40.62% of Safi's rocky coast is highly susceptible to slope instability.
