The seamount, which has been dubbed as Mount Los Atlantes, has three inactive volcanoes each around 50km (30 miles) in diameter, with their bases over 2km under the ocean surface, according to researchers from Spain’s Geological and Mining Institute (CSIC). Some of the lost islands even, after all this time, still have their beaches intact. The team said that some of the beaches sit just 60m (200 feet) below the ocean’s surface. During the last ice age, when sea levels were far lower than they are today, the inactive volcanoes would have become islands again, which could have been used to inhabit wildlife (Picture: IGME-CSIC)
