Off the coast of Iceland on the morning of 14 November 1963, the crew of a lone fishing trawler spotted an alarming sight. Off to the southwest of the Ísleifur II, a column of dark smoke was rising from the water. Concerned that it could be another boat on fire, the captain directed his vessel towards the scene. Once there, however, they found not a boat but a series of violent explosions producing ash. This was an unmistakable indication of a volcanic eruption taking place underwater, close to the surface. Very aware of the potential danger but eager to watch, the crew kept their boat nearby. It was indeed a remarkable event that they would witness a small part of over the course of that morning: the formation of a brand-new island.
Although now quite visible, the eruption lasted for much, much longer than the Ísleifur II would have been able to watch. After several days, the volcano had broken the water’s surface, forming an island over 500 meters long and 45 meters tall. Even though the rough tides of the North Atlantic might have soon eroded the new island away, it was named Surtsey, meaning ‘Surtur’s island’ – Surtur (or Surtr) being a fire giant of Norse mythology. The island proved to be tenacious, however. The eruption was ongoing and Surtsey increased in size more quickly than the ocean could wear it down. In the meantime two other nearby volcanic eruptions produced the beginnings of islands, but neither lasted very long. By April 1964, though, the most violent parts of the eruption were over and Surtsey remained.
