This paper reports the results of a study on the estimation of the deformation of the Italian Campotosto Lake dams and bridge due to the earthquake series recently occurring in the Central of Italy and still ongoing. The analysis is performed by processing a stack of 180 synthetic aperture radar (SAR) interferometric images, observed by the Italian satellite system COSMO-SkyMed (CSK) and 74 interferometric SAR images, collected by the European Space Agency (ESA) satellite system Sentinel. Results show an ongoing negative subsidence at the location of the main Campotosto lake dam infrastructure and the main bridge connecting two opposite roads. The work reveals information about the Earth surface deformation, which might be useful in order to track the subsidence caused by the recent earthquake series occurring in the center of Italy and, hence, for a correct administration of the dam and an efficient technical maintenance of the local territory.
