Rock falls in central Italy (Abruzzo Region) occur within the chain area, at the junction between the chain area and the piedmont and between piedmont hills and coastal sectors with wide coastal cliffs. This work focuses on the multidisciplinary analysis of rock falls affecting fault homocline ridges and, particularly, on the case of the San Venzanzio gorges (Aterno river) well known for rock falls particularly after the 2009 L\u2019Aquila eartquake. The gorges are located along the Aterno river within the central Apennines, between L\u2019Aquila and Sulmona, in a geological and geomorphological context typical of the Apennines chain. The analysis is based on 1:5.000-1.10.000 field geological and geomorphological mapping integrated with reported events analysis,photogeological analysis, laser scanning and geomechanical investigations. This approach is considered vital for a correct investigation of rock fall hazard and susceptibility, particularly on large slopes where topographical, geological, tectonic, geomechanical and geomorphological variation control rock fall development.
