In the early hours of 30 October 2016, a 6.5 magnitude earthquake struck central Italy. Scientists from Italy’s Institute for Electromagnetic Sensing of the Environment combined several pairs of Copernicus Sentinel-1 radar images acquired between 25 October and 1 November 2016 to analyse ground displacements caused by the quake. The results show ground subsiding or sinking down to 60 cm around Castelluccio. Around Norcia, there is an uplift of about 12 cm.
The work was carried out under the coordination of the Italian Department of Civil Protection, and in collaboration with Italy’s National Institute for Geophysics and Volcanology.
