Geomorphological map of Mt. Pruno southern slope, Roscigno, Cilento, Vallo di Diano and Alburni Geopark

This work refers the application of the method proposed by Dramis et al. (2011) to the gravitational phenomena mapping that affect the southern slope of Mount Pruno, the highest peak of the Roscigno municipality (Cilento, Vallo di Diano and Alburni Geopark) as operative contribution to the geomorphological mapping applied to landslide risk management end their mitigation on hilly area on structurally complex terrains. The Mount Pruno area is located in the upper section of the Calore Salernitano river basin; this area is characterized by the outcropping of terrigenous formations defined “Internal Units” (Cammarosano et al, 2004) which promote the establishment of a complex deepening hydrographic network from at least Early Pleistocene (De Riso & Santo, 1997). This peculiar geomorphological setting favours big landslides processes on the slopes with intermittent and long-term evolution. This representation can be considered a hierarchical and a multiscale mapping: once a focal level (scale) it’s been established, it’s possible to move to a larger or a smaller scale by polygon decomposing or generalizing operations; in this nested sequence each hierarchy level summarize the effects of the lower levels (Dramis et al, 2011).
