No structure this thick has ever been found before, according to the team – who say it could help to answer one of the biggest questions about the famous island.
Bermuda sits on a raised area of ocean crust known as an 'oceanic swell', which lifts it above the surrounding area.
These formations are typically associated with volcanic activity, but there is no evidence to show that a volcano is to blame for Bermuda's strange geology.
There hasn't been an eruption on the island for more than 31 million years, and any volcanic swelling should have subsided over that time.
The new discovery suggests the last eruption injected molten rock into the crust where it froze into a raft, lifting the island 500 metres (1,640 ft) out of the sea.

Triangular shaped?
ReplyDeleteNot big enough for the whole Bermuda Triangle, but it might account for some anomalies in and around the island group. I'm more curious about the fact that it supposedly lifted the area so high above sea level when the islands, currently, are only just barely above sea level.
