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.

Landnam (silicic)	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.

Ashik ash	Plinian	-8449.5	300		doi:10.1002/jqs.1066	position below the Saksunarvatn tephra and above the Vedde Ash indicates an early Holocene age. Pyne-O'Donnell (2007) places it above the Pre-Boreal Oscillation.
Torfajökull AD1477	Ultra-Plinian	1477.5	1	Calendar	doi:10.1191/095968399669624108	AD 1477 historical (the eruption was triggered by rifting within the Veidivotn volcanic system). Sometimes called Veidivotn AD1477. Larsen (1984) suggests an age of 1480 ± 11.
