NW-SE-trending normal fault systems on the northeastern and southwestern margins (Bernini & Papani, 2002, Di Naccio et al. , 2013, Bonini et al. , 2016, Molli et al. , 2018) (Fig. 1a). Southward it passes to the narrower Garfagnana basin and here, at the transition between the two basins, occurred the most destructive seismic event ever recorded in the Northern Apennines (i.e., the 1920 Mw 6.5 Garfagnana earthquake). Other moderate but still damaging seismic events hit the Lunigiana historically, particularly in 1834 (Mw~6.0), 1837 (Mw~5.9) and 1481 (Mw~5.6).
