For centuries, scholars have grappled with the enigmas of the Bermuda Triangle, yet a clear explanation for the anomalous occurrences there has remained elusive. It now appears that science has achieved a significant breakthrough toward comprehending these phenomena.
The Bermuda Islands rest upon an uplifted segment of the ocean floor, known as an “oceanic swell.” Such formations are typically associated with volcanic activity, yet this specific region has seen no eruptions for over 31 million years. Given this geological timeframe, such volcanic swells are theoretically expected to have subsided.
Researchers focused on this issue, presenting their findings in the journal Geophysical Research Letters. The specialists examined readings from a seismic station situated on the Bermuda Islands, tracing the origins of distant yet substantial earthquakes that traveled through the rock layer approximately 50 kilometers beneath the islands.
Within this area, they discovered a massive rocky formation described as “unlike anything else on Earth.” A stratum of rock, roughly 20 kilometers thick, lies beneath the oceanic crust in this location. However, this layer possessed lower density than the surrounding rock, consequently enabling it to both deflect passing seismic waves and elevate the islands.
It was previously established that the ancient lava on the Bermuda Islands exhibits low silica content. This indicates that the material originated from a deeper terrestrial layer with a very low concentration of carbon. This specific element might have been introduced deep within the Earth’s mantle during the breakup of the supercontinent Pangaea and the subsequent formation of the Atlantic Ocean.
This process could account for the differences observed between the Bermuda Islands and analogous structures in the Pacific or Indian Oceans, which were formed within older oceanic basins.
