These volcanoes were once part of a system of islands that sat around the east of Lanzarote, off the coast of West Africa, during the Eocene era around 56 million years ago, CSIC said. Geologist and project coordinator Dr Luis Somoza told LiveScience: ‘This could be the origin of the Atlantis legend’ referring to the Ancient Greek philosopher’s tale. In a statement he said: ‘They were islands in the past and they have sunk, they are still sinking, as the legend of Atlantis tells. Some of us have been able to verify that they still maintain their beaches’ (Picture: IGME-CSIC)
