Satellite differential SAR interferometry for the evaluation of effects of hydrogeological disasters: definition of a scale for damage evaluation
Main Article Content
Abstract
In this paper we present the results of monitoring soil movements over an about 10 km2 area around the border between
the Calabria and Basilicata regions in Italy. Monitoring has been performed using the satellite differential SAR
interferometry measurements integrated with GPS measurements. In particular, we used ERS data acquired at time
interval of several months (about two acquisitions per year), and after particularly strong pluvial events. Terrain displacement
spatial and temporal analysis has been performed by employing the original method described in Berardino
et al. (2002, 2003). Obtained results allow us to characterise unstable areas, and can be used within projects aimed
at territory classification and characterisation, and at performing damage evaluation. Accordingly, this technique has
been included in the framework of a proposed UE project (WEDELOP project) aimed at developing an integrated
methodology to devise a damage scale for hydrogeological disasters. This scale is of great interest in many fields; in
particular, definition of a damage scale would be highly desirable from the viewpoint of insurance companie
