“…During the ~600-415 ka interval, the Vulsini, Sabatini, Colli Albani, Volsci and Roccamonfina volcanic complexes were all simultaneously active (e.g., Sottili et al, 2004;Rouchon et al, 2008;Boari et al, 2009;Palladino et al, 2010;Soligo and Tuccimei, 2010). Around ~415 ka, volcanic activity also started at Vico volcano (Pereira et al, 2020). Finally, the onset of volcanic activity at Neapolitan volcanoes occurred around ∼300 ka (Rolandi et al 2003), although there is growing evidence from distal settings which reveal significantly older activity in this region, extending as far back as at least 560 ka or perhaps more (e.g., Giaccio et al, 2014;Petrosino et al, 2015;Wagner et al, 2019).…”
