The purpose of this work was the multitemporal analysis of two landslides, called "Boviero" and "Cimitero", which took place in Motta Montecorvino area (Foggia). It has been studied the geomorphologic evolution of Boviero and Cimitero' s slopes together with the morphometric features of these landslides, so as to get to the geomorphology of these slopes since 1869 to 2011. In order to realize this work, several studies had been made: the geomorphologic observance of the area, the digital and photo interpretative analysis of aerial photos by Leica Photogrammetry Suite 2011, the extraction of Digital Elevation Model (DEM) with digital photogrammetric techniques and finally Terrain Analysis studies on multitemporal raster DEM. The Cimitero slope was strongly subject to landslides since 1869 to 1976, with other 33 years of moderate or almost absent activity. Instead the Boviero one was strongly subject to landslides since 1869 to 1954, with a subsequent limited activity.
