Scientists have discovered a thick layer of low-density rock beneath Bermuda, which may explain the island's unusual buoyancy and the persistent swell supporting it, despite the absence of recent volcanic activity or a mantle plume. This underplating could be a remnant of volcanic activity from 30-35 million years ago, helping Bermuda stay above water until sea levels rise further.

Scientists have discovered a massive, dense rock structure beneath Bermuda that explains its appearance of floating in the ocean. This unique layer, formed over millions of years after the island's volcanic activity ceased, acts like a raft within the tectonic plate, raising the ocean floor and preventing Bermuda from sinking. The discovery was made using seismic data from earthquake recordings, revealing a layer not seen elsewhere in the world.

A recent study using earthquake wave analysis revealed large, persistent magma pockets beneath several dormant Cascade volcanoes, indicating that these volcanoes still hold significant melt at depth, which could influence future volcanic activity. The findings highlight the importance of continuous monitoring and advanced imaging techniques to better understand volcanic behavior and potential eruption risks.
