Giant structure discovered deep beneath Bermuda is unlike anything else on Earth

Bermuda archipelago: aerial view of Bermuda, the most significant islands are connected by bridges and appear to form one landmass - blue waters of the Atlantic Ocean and from the right the islands of St George, Higgs and Horseshoe, Hen, Peggy, Whalers, Governor, Paget, Smith, Brooks, Oswego, St. David (airport), Nonsuch, Coney, Bermuda, Ireland, Somerset. .

Move aside, Bermuda Triangle: The newest North Atlantic mystery lies beneath this enigmatic archipelago. Scientists have discovered a strange, 12.4-mile-thick (20 kilometers) rock layer below the oceanic crust under Bermuda. This level of thickness has never been seen in any other similar layer worldwide.

"Typically, you have the bottom of the oceanic crust and then it would be expected to be the mantle," said study lead author William Frazer, a seismologist at Carnegie Science in Washington D.C. "But in Bermuda, there is this other layer that is emplaced beneath the crust, within the tectonic plate that Bermuda sits on."
