Upper panel—Real-time scenario estimated ground motion (Up component) through VADASE. Bottom panels—sTEC variations for all the satellites in view for all the GPS stations computed through VARION in range of 1500 km from the epicenter (left panel) and a zoom in the range of 150 km (right panel). In both cases, positive and negative distances represent respectively the IPP position at 8 min after the earthquake placed north and south the epicenter.
