Veidivotn AD1717	Sub-Plinian	1717.5	1	Calendar	doi:10.1111/j.1502-3885.2007.tb01176.x	AD 1717 historical
SvV	Sub-Plinian	-659.5	300		doi:10.1016/s0921-8181(99)00011-9	c. 2500 14C yr BP at Svinavatn, N Iceland (Boygle 1999)
FMAZ I-THOL	Plinian	-16649.5	500	Marine04	doi:10.1016/j.quascirev.2006.03.001	tholeiitic ash layer dated to c. 15,400 14C yr BP in Wastegard et al. (2006). Thought to be equivalent to 15.4 ka BAS-1 of Haflidarson et al. (2000).
NGRIP 1595.1m	Sub-Plinian	-12499.5	1	GICC05	doi:10.1002/jqs.908	cf. 15.4 ka-BAS-1 tephra based on major element chemistry but SS09 age of 14428-14431 ice core years makes such a correlation highly unlikely. The depth suggests a GICC05 age of 14500 ± 180 b2k.
I-THOL-1 (Tv-3)	Sub-Plinian	-9064.5	225		doi:10.1111/j.1502-3885.1992.tb00009.x	One of components of NAAZ I with age of ~10.4 ka 14C yr BP (Kvamme et al. 1989). Could be equivalent of Tv-3 in lake Torfadalsvatn with age of ~9.7 ka 14C yr BP (Bjorck et al., 1992).
Sandoy B	Plinian	-9279.5	42	IntCal09	doi:10.1016/j.quaint.2011.05.014	14C modeled age of 11,288-11,205 yr cal BP (Lind & Wastegard 2011)
Sandoy A	Plinian	-9379.5	42	IntCal09	doi:10.1016/j.quaint.2011.05.014	14C modeled age of 11,388-11,305 yr cal BP
Landnam (basaltic)	Sub-Plinian	871.5	1	GICC05	doi:10.1016/0012-821x(95)00145-3	c. AD 871 ± 2 (GRIP). The Landnám tephra layer is characterised by two distinct tephra components: a lower rhyolitic tephra layer which is overlain by a basaltic tephra layer. Both of these were deposited following the ~AD 871 Vatnaöldur eruption which saw simultaneous eruptions of the basaltic Veidivötn-Bárðarbunga volcanic system and the silicic Torfajökull complex.
