    Differential Synthetic Aperture Radar Interferometry (DInSAR) plot of the deformation time-series for a coherent pixel located in the Volturno River area (South Italy). The time-series has been obtained by applying the Small BAseline Subset (SBAS) algorithm to a set of 64 data acquired along ascending orbits by the SAR system mounted on-board the ENVISAT satellite of the European Space Agency (ESA) during the 2003-2010 time period. Note that the DInSAR deformation measurements (that provide a measurement of the ground deformation projection along the radar line of sight, LOS), are referred to a pixel located within the Napoli City harbour.

    Differential Synthetic Aperture Radar Interferometry (DInSAR) mean deformation velocity map (in colour) of the Napoli Bay area (South Italy), computed in coherent pixels, only, and superimposed on the SAR amplitude image (grey scale representation) of the zone. The map has been obtained by applying the Small BAseline Subset (SBAS) algorithm to a set of 64 data acquired along ascending orbits by the SAR system mounted on-board the ENVISAT satellite of the European Space Agency (ESA) during the 2003-2010 time period. Note that the red colour corresponds to a sensor-target range increase; moreover, all the DInSAR measurements (that provide a measurement of the ground deformation projection along the radar line of sight, LOS), are referred to a pixel located within the Napoli City harbour.
