Oblique aerial view looking north-northwestwards of the island of Heimaey, Vestmannaeyjar, Iceland, in August 1966, showing the fishing town of Vestmannaeyjar, the east-west-trending harbor in the background, and the extinct volcano Helgafell rising to 741 ft in the right center of the island. On January 23, 1973, lava began to pour from a 0.9-mi north-northwest-trending fissure to the east (right) of Helgafell. Eldfell eventually grew to be similar in height to Helgafell, 0.6 mi to the northeast.
