Abstract

Surface soil movements can be the expression of gravitative or tectonic events. Two tech- niques like InSAR (data obtained by ERS1-2 European satellite) and aerial photo analysis (Volo Italia, 1988-89) have been combined to study these movements, in northern-central por- tion of Sicily region (Southern Italy) and in the Lucanian Apennines (“axial zone” of the south- ern Apennines, Italy). This integrated approach allows to detect and classify slow movements as Deep Seated Gravitational Slope Deformations (DSGSD). The investigated areas are morphologically characterized by significant elevation changes due to the presence of high mountainous peaks, separated from surrounding depressed ar- eas by steep escarpments. Consequently, relief energy favours the development of gravity- driven deformations. They seem to be superimposed on and influenced by the inherited struc- tural and tectonic pattern, related to the sin- and post-thrusting evolution.
