ADVANCED DIFFERENTIAL INTERFEROMETRIC SAR TECHNIQUE A-DINSAR FOR THE STUDY OF LARGE LANDSLIDES

Abstract

Large landslides are widespread both in the Alps and in Apennines; the observed movements are generally from extremely slow to slow with some occasional acceleration; the sudden and paroxysmal collapse of the whole mass may have catastrophic consequences. They are also difficult to characterize in their boundaries and state of activity and to monitor with traditional tools. The Advanced Differential interferometric SAR (Synthetic Aperture Radar) technique, A-DInSAR, is a remote sensing technique, which is based on satellite radar imagery for the ground motion measurement. It is based on large stacks of SAR images and enables the measure of small displacement of the ground with a millimetThe aim of this study is to apply the A-DInSAR technique in some large landslide in Alps (Brenvetto, Rosone and Alpe Baranca landslides) in order to study the effectiveness of the technique in their study and monitoring.
