A new supervolcano brewer under Massachusetts, Vermont and New Hampshire

Somewhat unexpected has gradually become known to geologists in the United States. A large mass of molten rock creeps up under the nation's northeastern state.

"The onset we discovered is like a hot air balloon and we see that something rises through the deeper part of our planet under New England," says Rutgers University geophysicist Professor Vadim Levin.

Traces of bridging mass were shown only through a large-scale new seismic study.

The idea that there may be a super volcanic brewing under Massachusetts, Vermont and New Hampshire is something of a surprise.

"Our study challenges the established concept of how the continents we live on," says Professor Levin. "It challenges the textbook concepts taught in introductory geology classes."

The region is geologically stable. There are no active volcanoes.

So the massive magma building must be a relatively new event.

But in the time scale of the geological processes of the earth it still means tens of millions of years.

"It's likely to take millions of years for the excitement to get where it goes," says Professor Levin. "The next step is to try to understand how exactly it happens."

Something strange had been noted about the region earlier. Somewhere down there was an anomaly hundreds of degrees Celsius warmer than its surroundings.

The new study has helped identify the molten blob centered under Vermont, with parts of West New Hampshire and Western Massachusets also within its prudence.

"It's not Yellowstone-like, but it's a distant relative," said Professor Levin.

As to whether or not the magma bubble eventually echoes the path to the surface unknown.

"Maybe it did not have time yet, or maybe it's too small and will never do it," said Professor Levin National Geographic .

"Come back in 50 million years and we will see what's happening. "
