Data analysis of RAN network records are shown for the May 20th event. Particularly, 6 stations closer to the epicenter (MRN, MDN, NVL, ISD, CPP, ZPP) have been considered. To easily visualize them, the following map could be helpful. For each of the three components – South-North (SN, blue), Est-West...

Data from the radar satellite COSMO-SkyMed of the Italian Space Agency (ASI) has shown the surface ground deformation, allowing researchers from CNR-Irea and INGV to carry out the first evaluations of the affected area. A part of the studied area shows that a deformation up to 15 centimetres occurred....
