DESCRIPTION:Hydro geological instabilities involving urban areas represents
  a potential threat for structures and people. An in-depth knowledge of th
 e spatial and temporal evolution of the ground surface and the related dis
 placement field becomes then essential for mitigating and managing the ris
 k associated with these phenomena. In this context\, Multi-Temporal Interf
 erometric Synthetic Aperture Radar (MTInSAR) techniques are gaining moment
 um in the monitoring of built regions affected by landslides. The presente
 d research wants to provide an example of the benefit in using Copernicus 
 C-band Sentinel-1 SAR products to support the management/mitigation strate
 gies in case of building settlements in urban areas. To this aim\, Sentine
 l-1 SAR acquisitions and ground meas-urements (i.e. high-precision geometr
 ic levelling) have been jointly used to investigate an ongoing instability
  occurrence\, affecting the town of Chieuti\, located in the Apulia region
  (Southern Italy). Furthermore\, a geostatistical analysis has been develo
 ped in a Geographic Information System (GIS) to compare the Sentinel 1 SAR
  dataset with the results obtained from the ground-based geomatics observa
 tions. The study evidences the effectiveness of using Sentinel-1A SAR data
  as a long-term routine monitoring tool for millimetre-scale motions in ar
 eas involved by ground in-stabilities triggered by landslides. The outcome
 s of this analysis helped the design of the mitigation measures implemente
 d for securing the study area\, demonstrating once again the importance of
  satellite remote sensed SAR data in driving land management strategies an
 d civil protection actions where potentially dangerous instability phenome
 na are underway
