The largest volcanic region on Earth
And no one even knew it was there
Using ice-penetrating radar, Edinburgh University researchers have discovered 91 subglacial volcanoes hiding more than a mile (2km) below the surface of the west Antarctic ice sheet.
The volcanoes, which are considered active, range from about 330 feet (100m) to 12,600 feet (3850m) tall, more than 1000 feet taller than Oregon’s Mt. Hood. Even at that height, the subglacial peaks are still covered by a dense layer of ice. (The ice is more than 2.4 miles (4km) thick in the region.)
“If one of these volcanoes were to erupt it could further destabilise west Antarctica’s ice sheets,” said glacier expert Robert Bingham, one of the paper’s authors.
“We were amazed,” said Bingham. “We had not expected to find anything like that number. We have almost trebled the number of volcanoes known to exist in west Antarctica.”
The researchers also suspect there are even more volcanoes rising from the sea floor beneath the Ross ice shelf. “(This) would make this region the densest region of volcanoes in the world, greater even than east Africa, where mounts Nyiragongo, Kilimanjaro, Longonot and all the other active volcanoes are concentrated,” said Bingham.
In addition to the 91 newly discovered volcanoes, 47 volcanoes have been previously discovered in the region.
Gee, I wonder what is melting the ice?

“Here is even more vindication for this site,” says K.B.
“Of course, volcanoes are caused by CO2! Didn’t you know that?!” asks Jimmy.
