@Fab Foodie The Gran Sasso is right next to the earthquake area... Based on evacuation advice in August I would be prepared to take a diversion (south) if you are told to.
Thankfully there seems to have been few injuries and deaths* from these 3 quakes because sadly the area was already flattened in August and after the large foreshock on Wednesday and then biggie on Wednesday the Marche region (not sure what the other regions did but probably similar) put into place extensive evacuation plans. I experienced the quake in August FF, hope you're all right and safe journey. One of the sentinel 1 satellites is flying overhead today and that may bring more information as to the risk from a further quake from particularly the Mt Vettore or Mt Laga faults. The Laga fault is right next to the fault system of the Gran Sasso range!
*It's reported that someone died of a heartattack at the shock of the earthquake on Wednesday.
