Something unexpected is gradually making themselves known to geologists in the United States. A huge mass of molten rock crawls to the top among the nation of the north-eastern states.
“The surge we detected is like a hot-air balloon, and we conclude that there is something to increase due to the deeper part of our planet in New England,” says Rutgers University geophysicist Professor Vadim Levin.
Traces of the brooding mass only became clear by means of a large-scale new seismic study.
The idea that there is a super volcano brewing under Massachusetts, Vermont and New Hampshire is something of a surprise.
“Our study challenges the established notion of how the continents on which we live behave,” Professor Levin. “The challenges of textbook concepts learned in the introductory geology classes.”
The area is geologically stable. There are no active volcanoes.
So the huge magma build-up must be a relatively recent event.
But, in the time scale of the Earth, geological processes, this still means dozens of millions of years.
“It will probably take millions of years for the movement to get where it’s going,” Professor Levin explains. “The next step is to try to understand exactly how it happens.”
There is something strange is noticed about the region previously. Somewhere down there was an anomaly that is hundreds of degrees Celsius) warmer than its surroundings.
The new study has helped in identifying the melted blob if it is centered under Vermont, with parts of western New Hampshire and western Massachusetts also in her embrace.
“It’s not Yellowstone-like, but it is a distant relative,” Professor Levin.
If the all-or-not the magma bubble will eventually eek its way to the surface, is unknown.
“Maybe it’s not time yet, or maybe it is too small and will never make it,” Professor Levin told National Geographic.
“Come back in 50 million years, and we’ll see what happens.”
