This event damaged a region which, differently from the adjacent L’Aquila sector of the Apennines, was not characterized by a significant seismic history. The scientific and popular view of a territory seismically negligible was still further contradicted eleven years later, on 13 January 1915, when the same area was struck by a catastrophic event (Mw 7.08 [B1: Rovida et al., 2022]), responsible for new damage (in some cases complete destruction) of the settlements already damaged in (and repaired...
