Subsidence monitoring in Sarno urban area via multi-temporal DInSAR technique

In this study Differential Interferometric Synthetic Aperture Radar (DInSAR) is used to investigate the effects of a subsidence phenomenon - related to groundwater withdrawal - on ancient low-rise masonry buildings located in the urban area of Sarno, Italy. ERS-1/2 SAR data from 1992 to 2002 were analysed and results were validated with geodetic data. The results encourage future developments for study and use of the multi-temporal DInSAR technique in the mitigation of subsidence risk.
