Analysis of subsidence phenomena via DInSAR data at different scales

Since early 2000 a number of case studies have been proving Differential Interferometry Synthetic Aperture Radar (DInSAR) data as a powerful tool for the detection, mapping and monitoring of ground displacements associated with natural or anthropogenic phenomena. Moreover, several projects all around the world provided rich data archives whose confident use, however, should rely on multidisciplinary expert interpretations. To this aim, the present work describes and applies a set of original procedures for the use of DInSAR data in the analysis of subsidence phenomena and the related consequences to the exposed facilities. With reference to the case study of the Campania region (southern Italy), where widespread ground displacements occurred and damage of different severity was recorded to buildings, the paper presents the results obtained at different scales of analysis via high/very high resolution SAR sensors.
