FMAZ II (Fugloyarbanki)	Plinian	-24739.5	1	GICC05	doi:10.1002/jqs.1182	26740 ± 390 yr b2k in NGRIP 1848.05
Borrobol	Plinian	-12094.5	95	IntCal09	doi:10.1002/jqs.1498	Best current estimate is 14.14-13.95 cal ka BP (Bayesian age model). Replaces Turney et al. (1997) date of c.14.4 cal ka BP. Davies et al. (2004) suggestion of 2 eruptions has been revised by Matthews et al. (2011).
L3574	Plinian					No age given, reported as 'older than Saksunarvatn tephra' by Dugmore and Newton (1997). Turney et al. (2006) suggests an age of c. 10.8 ka cal. BP.

Breakish Tephra	Plinian				doi:10.1002/jqs.1066	no date suggested although position above the Ashik tephra and Saksunarvatn indicates an age in the early-mid Holocene.
DOM-6 'microlite' tephra	Plinian	-696.5	35		doi:10.1006/qres.2002.2325	c. 730-664 cal BC radiocarbon (van den Bogaard et al. 2002). According to Hall & Pilcher (2002) this is probably equivalent to the OMH-185 (Barnsmore) tephra.
GB4-182	Plinian	-1349.5	200		doi:10.1191/0959683602hl538rr	c. 1350 cal BC interpolated (Hall & Pilcher 2002)

Lough Portain B	Plinian		0		doi:10.1177/095968369500500301	sub-population of Hekla AD 1510 eruption (Lough Portain A). Status is unclear, not a distinct isochrone
MOR-T4	Plinian	1000.5	100		doi:10.1191/0959683604hl749rp	c. cal AD 1000 interpolated (Chambers et al. 2004)

Vallensgard Mose tephra	Plinian				doi:10.1002/jqs.990	Stratigraphic position is similar to Vedde Ash, in the middle of the Younger Dryas, but geochemistry is different. Unclear if this is a significant tephra horizon.
NAAZ I	Plinian	-10449.5	500	Marine04	doi:10.1016/j.quascirev.2006.03.001	Diffuse layer representing c. 11 ka 14C yr GS-1 ash zone containing components from I-Thol-2 (Grímsvötn), I-Rhy.1 (Katla) and I-Thol-1 (Veidivötn). It is commonly believed that the biggest contributor is the rhyolitic component of the Vedde Ash.

5d-BAS	Plinian	-109549.5	5000	Orbital	doi:10.1016/s0277-3791(98)00038-9	Probably represents an eruption complex. Several geochemical populations: BAS-I, BAS-II, BAS-III.

Several geochemical populations: RHY, INT, BAS & TAB (the 5e-Midt/TRACHY is believed to be from Jan Mayen). Wallrabe-Adams & Lackschewitz (2002) suggest either Vatnafjoll or Vestmannaeyjar may be the source.
5e-Low	Plinian	-127549.5	5000	Orbital	doi:10.1016/s0277-3791(98)00038-9	Probably represents an eruption complex. Several geochemical populations. Wallrabe-Adams & Lackschewitz (2002) suggest either Vatnafjoll or Vestmannaeyjar may be the source.
