The Surtsey Eruption 1963-1967. The Surtsey eruption is among the longest eruptions to have occurred in Iceland in historical times. The first sign of an eruption came early in the morning of November 14, 1963, at a site approximately 18 km southwest of Heimaey, the largest of the Vestmannaeyjar (Westman Islands). total of 1.1 kmÂ³ of volcanic products arose from the Surtsey eruption, of which 60-70% were tephra and 30-40% lava. In many respects the Surtsey eruption is comparable to eruptions that led to the formation of hyaloclastite (palagonite) mountains in Iceland during the Ice Age.
