Krafla

Lava fountains play along an eruptive fissure at Iceland's Krafla volcano early in the morning on September 5, 1984. During the first hours of the eruption, which began just before midnight on the 4th, two eruptive fissures joined to become active along a total length of 8.5 km. As is often the case with fissure eruptions, activity was later concentrated along a localized part of the fissure.

Incandescent lava fountains play above an eruptive fissure at Krafla volcano in NE Iceland on September 6, 1984. After a quiet interval of 33 months, an eruption began on September 4 along a fissure extending from Leirhnjœkur 8.5 km to the north. Initially, the fissure was active along its entire length, but later lava production was highest at the northern end of the fissure.
