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.
