Vedde Ash	Ultra-Plinian	-10170.5	1	GICC05	doi:10.1029/2005jd006079	Bi-model rhyolitic and basalt ash layer, c. 12171 ± 114 yr b2k (GICC05); alternatively NGRIP SS09 11985-11988 ice core yr BP. Norddahl and Haflidason (1992) have suggested that the Skogar tephra is the proximal correlate of the Vedde Ash.

Eldgja tephra	Sub-Plinian	934.5	1	GICC05	doi:10.1177/095968369500500201	notes c. AD 938 ± 4 (GISP2) or AD934 ± 2. Katla~1000 and K-x are now believed to correspond to this eruption (G. Larsen, 2010, Katla: tephrochronology and eruption history, in Schomacker et al. [eds.] 'The Mýrdalsjökull Ice Cap, Iceland: glacial processes, sediments and landforms on an active volcano', Developments in Quaternary Science vol. 13, pp.23-49, Amsterdam: Elsevier).

Mjauvotn A	Plinian	-4399.5	200		doi:10.1191/095968301668079904	c. 5300-5700 14C yr BP radiocarbon. A mid-distal basaltic tephra (Tv-5) dated to c. 6000 BP with a similar geochemistry to this tephra has been recorded in the sediment succession from Lake Torfadalsvatn on northern Iceland (Bjorck et al., 1992).
Mjauvotn B	Plinian	-4399.5	200		doi:10.1191/095968301668079904	c. 5300-5700 14C yr BP radiocarbon
Torfadalsvatn (Tv-5)	Sub-Plinian	-4954.5	240	IntCal09	doi:10.1111/j.1502-3885.1992.tb00009.x	Transitional alkali basalt. Dated at Lake Torfadalsvatn to 6000 ± 140 14C yr BP (c.7240-6500 cal BP, 2 sigma). Possibly the mid-distal equivalent of Mjauvotn A tephra on the Faroes (Wastegard 2001). On the basis of major element geochemistry believed to be from Katla.
SILK-A1	Sub-Plinian	-4009.5	207	IntCal09	doi:10.1002/jqs.724	c. 5170 ± 85 14C yr BP (Wastegard 2002, JQS 17(8), 723-730). Calibrates to 6182-5730 yr cal BP (2 sigma).

SILK-YN	Sub-Plinian	310.5	70	IntCal09	doi:10.1179/env.2000.5.1.21	There are three 14C ages for this tephra, from 1500 ± 70 to 1880 ± 60 14C yr BP. Dugmore et al. (2000) argue for an age of 1740 ± 50 14C yr BP. Calibrated age range of 1811-1539 cal BP (2 sigma).
