Ribbons of molten lava dance above a vent at Krafla volcano in October 1980 during a period of low-intensity activity. Four eruptive episodes occurred at Krafla during 1980. One of these, a brief episode of phreatic activity on June 15, was explosive. The other three eruptive phases, in March, July, and October, were dominantly effusive.
