Title: Source fault of Italy's earthquake

Copyright: Contains modified Copernicus Sentinel data (2016)/ESA/INGV


Scientists from Italy's National Institute for Geophysics and Volcanism combined Sentinel-1 radar acquisitions over central Italy from before and after the 24 August earthquake to calculate the location, geometry and amount of slip on the source fault. The slip is distributed mainly in two patches of about 1 m. The aftershock seismicity (black dots) is clearly surrounding these patches, releasing the remaining stress along the fault. The red star is the main shock. Green stars indicate the highest aftershocks of the sequence (M > 4.3).
