Description :
This paper deals with a big earthflow, known as Pietra Maura landslide, which has an artificial reservoir, formed by an earthfill-rockfill dam, at its toe. The landslide is located immediately north of Marsico Nuovo village along the eastern flank of the high Agri Valley. The geological evolution of the Agri Valley is essentially related to the Pleistocene extensional and strike-slip tectonics, overprinting older Apennine contractional structures. The geological formations recognized in the study area are all related to the Lagonegro Basin domain. They are mostly characterized by abundant clay intervals, sudden lithological variations and diffuse structural complexities. The aim of the study is to achieve a better understanding of the stability conditions in the northern area of the Marsico Nuovo dam. It highlights the presence of landslide bodies, which are totally or partially reactivated or susceptible to reactivation such as the Pietra Maura landslide. - (NF)
