But what was once thought to be an ancient underwater "lost city" is actually a naturally occurring phenomenon, scientists have found. "These gas leaks are quite common, they're not an unusual phenomenon -- the earth's crust is quite a leaky material." New research published in the Marine and Petroleum Geology journal today reveals the ancient underwater site was actually created by a natural geological phenomenon around five million years ago. "We investigated the site, which is between two and five meters (six and sixteen feet) underwater, and found that it is actually a natural geological occurring phenomenon," Andrews said. While the "lost city" originally attracted divers, Andrews does not believe the new research will impact tourism.
