Scientists have discovered a vast and unusual rock formation beneath the seafloor of the Bermuda Triangle that could rewrite the geological history of Bermuda. The structure, located around 20 kilometers below the ocean floor, is unlike anything previously identified on Earth and may explain why Bermuda remains above sea level despite its long-extinct volcanic activity.
According to researchers, the newly identified formation is a roughly 20-kilometer-thick layer of rock lying beneath the oceanic crust. What makes it remarkable is its relatively low density compared to surrounding rocks, causing it to behave like a “geological raft.” This buoyant layer appears to support the Bermuda island, preventing it from sinking, even though volcanic activity in the region ceased millions of years ago—conditions under which the island would normally be expected to subside.
The discovery was made by analyzing seismic waves generated by distant earthquakes. As these waves traveled through the Earth, subtle changes in their speed revealed the presence and characteristics of the hidden rock layer.
Scientists believe the formation dates back to the breakup of the supercontinent Pangaea. During that period, intense volcanic activity allowed molten rock from the mantle to rise and become trapped within the crust, where it later cooled and solidified. This ancient process is now thought to be responsible for the anomalous structure beneath Bermuda.
While the finding adds a new geological dimension to the long-debated Bermuda Triangle, researchers caution against sensational interpretations. The discovery does not support supernatural explanations for the disappearance of ships or aircraft. Instead, it complements existing explanations such as severe weather conditions and human error, while introducing a previously unknown chapter in Bermuda’s deep geological past.
The study highlights how much of Earth’s subsurface remains unexplored—and how hidden structures beneath the oceans can still reshape our understanding of well-known regions.
