The work deals with the use of satellite radar interferometric techniques for the analysis and monitoring of ground instability in urban areas. Some various space-borne MTInSAR-based procedures by exploiting SAR data from LEO Satellites Sentinel-1 and COSMO-SkyMed constellations have been applied to italian built-up sites, at different scales from the screening of the urban fabric up to a building-scale analysis. In particular, a procedure on the assessment of the urban instability by PSI (Persistent Scatterers Interferometry)-based classification indexes has been tested in Orvieto 100 km north of Rome; a methodology for urban territory screening by means of PSI time series displacements has been performed on Pienza historical town that is included in the UNESCO WHL (World Heritage list); a procedure for generating empirical fragility and vulnerability curves from InSAR ground deformation rates and field damage survey was has been proposed for buildings exposed to slow-moving landslides on urban masonry settlements in Northern Appennine; a building deformation assessment for deriving differential settlement parametershas been applied in Volterra urban area in Central Italy. A short discussion on the relevant key points of each methodology is tacked, along with conclusions and future perspectives.
