A vast mass of hot rock is welling up underneath Vermont and extending into other subterranean regions below New England, new research shows.

Scientists used a network of thousands of seismic measurement devices in the largest geological study of its kind, detecting the enormous blob upwelling under Vermont, New Hampshire, and Massachusetts – and possibly elsewhere.

“The upwelling we detected is like a hot air balloon, and we infer that something is rising up through the deeper part of our planet under New England,” says geophysicist Vadim Levin from Rutgers University – New Brunswick.

Since New England doesn’t have any active volcanoes, the huge build-up is thought to be a geologically recent phenomenon, although in this case that means it could have slowly but steadily been growing for tens of millions of years.
