Spartel Island, currently submerged 60 meters beneath the Straits of Gibraltar, is believed by some to have once been above water, potentially influencing Plato's legendary account of Atlantis. A recent seafloor survey published in the journal Geology supports this hypothesis, suggesting that around 12,000 years ago, global sea levels were significantly lower, making it plausible for Spartel Island to have existed above sea level. The discussion highlights the possibility that the island could have been affected by natural disasters like tsunamis and subsidence during that period, contributing to its current underwater status.
