The crew of the Ísleifur II had just finished casting their nets off the coast of southern Iceland when they realised something was wrong. In the early morning gloom in November 1963, a dark mass filled the sky over the Atlantic Ocean. They rushed to the radio, thinking that another fishing vessel was burning at sea, but no boats in the area were in distress.
Then, their trawler began to drift unexpectedly, unnerving the crew further. The cook scrambled to wake the captain, thinking they were being pulled into a whirlpool. Finally, through binoculars, they spotted columns of ash bursting from the water and realised what was going on: a volcano was erupting in the ocean below.
