The viscous Laugahraun lava flow was emplaced in 1477 just inside the northern rim of Torfajökull caldera. Minor amounts of silicic tephra and lava were erupted from Torfajökull at the southern end of the Veidivotn fissure, which produced a major basaltic explosive eruption in March 1477. Three silicic lava flows--north and south Namshraun and Laugahraun--were emplaced near the northern margin of the Torfajökull caldera.
