Lava fountains rising from a vent along an eruptive fissure at Krafla feed an incandescent lava flow that travels east and then turns toward the north. This 15 September 1984 photo was taken near the end of a two-week eruption. An 8.5-km-long fissure, initially active along its entire length, fed lava flows that covered 24 km2. The peak rising above the clouds on the right is Eilifur, which likely formed in the Pleistocene.
