The silicic Hrafntinnuhraun lava flow and tephra were erupted about 870 CE at the SW end of a fissure system that also produced basaltic eruptions from the Vatnaoldur fissure of Bardarbunga volcano at this same time.  The Hrafntinnuhraun crater row was the source of the roughly 870 CE "Settlement Layer" tephra that forms a prominent time marker throughout SW Iceland.
