Abstract
An area of about 15 km2 in Central Italy, severely affected by landslide processes, has been studied by several approaches. Field surveys and multi-temporal aerial photos allowed to frame geomorphological setting and temporal evolution of instability slope processes. Starting from this information, Advanced Differential Interferometric SAR (A-DInSAR) analyses have been performed in order to improve our knowledge of the under study processes in terms of both spatial and temporal evolution and kinematics. A previous feasibility analysis has been carried out to define the suitability of A-DInSAR analysis for every recognized landslide. The adopted method was also useful to identify best available data to perform InSAR analyses in order to detect and measure expected deformation processes. A-DInSAR analyses have been performed with two different approaches: a standard Persistent Scatterers (PS) analysis with linear models to estimate PS velocity over the whole area and local scale analyses on some specific sub-areas with a no-model approach, more appropriate for non-linear deformation detection.
