spacetimewithstuartgary:Mapping Italy’s 30 October 2016 earthquakeTOP IMAGE….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 a Copernicus Sentinel-1B radar image from 26 October with a Sentinel-1A radar image from 1 November to analyse ground displacements caused by the quake. The results show ground deformations extending across about 130 sq km with a maximum displacement of about 70 cm (in the direction of the satellite), in the area of Castelluccio. 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. CENTRE IMAGES….Ground displacement from Italy’s earthquake Scientists from Italy’s Institute for Electromagnetic Sensing of the Environment combined Sentinel-1 radar acquisitions over central Italy from before and after the 24 August 2016 earthquake: 15 August, 21 August and 27 August 2016. The result shows vertical ground subsidence, reaching about 20 cm in correspondence to the Accumoli area, and lateral movement of up to 16 cm. The blue line indicates the location of the fault trace.BOTTOM IMAGE….Italy earthquake deformation Scientists from Italy’s Institute for Electromagnetic Sensing of the Environment combined Sentinel-1 radar acquisitions over central Italy from before and after the earthquake: 15 August and 27 August 2016.
