Surtsey was born in 1963. It was a great event for scientists. They were lucky enough to see the birth of this volcanic island. It began at 7: 30 a.m. on 14th November. A fishing boat was sailing near Iceland. The boat moved under the captain’s feet. He noticed a strange smell. He saw some black smoke. A volcano was erupting. The bottom of the grey Atlantic was open. Red-hot rocks, flames and smoke were rushing up from a split in the sea-bed. The island grew quickly. It was 10 meters high the next day and 60 meters high on 18th November. Scientists flew to Reykiavik to watch. It was very exciting. Smoke and flames were still rushing up. Pieces of red-hot rock were flying into the air and falling into the sea. The sea was boiling and there was a strange light in the sky. Surtsey grew and grew. Then it stopped in June 1967. It was 175 meters high and 2 kilometers long. And life was already coming to Surtsey. Seeds came over the sea. Plants grew. Birds came. Some scientists built a house to learn about the young island. A new island is like a new world.
