For decades, scientists have been puzzled by Bermuda's elevation above the Atlantic Ocean floor, despite its volcanoes having been dormant for over 30 million years. Recent research from Carnegie Institution for Science and Yale University reveals that a unique geological structure, a layer of unusually light rock over 12 miles thick, is responsible for this phenomenon. This buoyant layer, acting like a giant underground raft, was discovered through the analysis of seismic waves from global earthquakes, which provided insights into the Earth's interior beneath Bermuda. The researchers propose that this lighter rock formed from carbon-rich molten rock during Bermuda's volcanic activity, potentially tracing back to the ancient supercontinent Pangaea. The findings challenge traditional geological models, suggesting that Bermuda's features do not fit the common mantle plume theory used to explain volcanic islands. This discovery raises questions about other similar hidden structures beneath oceanic islands, indicating that Earth's geological processes may still hold many secrets.
