Subsidence in Pistoia

Ground deformation map of Pistoia in Tuscany. Using data acquired between 2014 and 2019 from the Copernicus Sentinel-1 mission, this map shows subsidence in red and uplift in blue. The colour red represents a significant level of risk where further analysis is needed. This information is routinely sent to the local authorities in charge of geohazard management practices. The subsidence values derived from the radar data have been overlaid on top of a Copernicus Sentinel-2 image.
