The Bermuda Triangle might no longer hold the title of the Atlantic Ocean's greatest mystery, as recent research conducted by scientists from Yale University and Carnegie Science has unveiled a striking geological find. In a study published in Geophysical Research Letters, the experts outline their findings that suggest a unique rock layer located beneath the oceanic crust could be responsible for the islands' structural integrity over millions of years, even as volcanic activity diminished.

This geological investigation revealed that beneath the Bermuda Islands lies a 20-kilometer thick layer of unusual rock, an unprecedented measurement in comparative geological studies worldwide. The discovery indicates that, as the volcanic activity on the surface waned, the tectonic plate moved away from the deep mantle hotspot, leading to cooling and a gradual descent of the crust and volcano. However, the unique rock layer appears to counteract this effect, pushing the island upward and preventing its sinking.

This finding not only offers insight into the geological stability of the Bermuda Islands but also challenges previous notions about the fate of landmasses after volcanic activity ceases. The implications could be significant for further studies related to tectonic activity, geological longevity, and the mysteries of the Bermuda Triangle, which has garnered both scientific and popular attention for decades.
