“…The activity of the SommaVesuvius complex started approximately after the Phlegraean Fields Campanian Ignimbrite super-eruption, 39 years ago (De Vivo et al, 2001), while the last Vesuvius eruption occurred in 1944 (Arnò et al, 1987). During the last 4000 years of activity, Vesuvius experienced several main explosive events: the smallscale Plinian eruption of AD 1631 (Rosi, Principe, & Vecci, 1993), the sub-Plinian AD 472 eruption (Arnò et al, 1987;Rolandi, Munno, & Postiglione, 2004;Rosi & Santacroce, 1983;Sulpizio, Mele, Dellino, & La Volpe, 2005, and the two large Plinian eruptions that occurred at AD 79 (Pompei eruption; Sigurdsson, Carey, Cornell, & Pescatore, 1985) and 1995 ± 10 cal BC (Avellino eruption; Rolandi, Mastrolorenzo, Barrella, & Borrelli, 1993;Sevink et al, 2011;Sulpizio, Cioni, et al, 2010). Mild explosive activity (from Strombolian and violent Strombolian to sub-Plinian) took place during intra-Plinian periods (Andronico & Cioni, 2002;Arrighi, Principe, & Rosi, 2001;Cioni, D'Oriano, Bertagnini, & Andronico, 2013;Di Renzo et al, 2007;D'Oriano, Cioni, Bertagnini, Andronico, & Cole, 2011), and a number of lava flows originated from the central crater ('Gran Cratere') or from fissures opened on the main Vesuvius cone ('Gran Cono') .…”
