US geologists have been surprised to find a huge magma blob under Massachusetts, Vermont and New Hampshire
SOMETHING unexpected has been gradually making itself known to geologists in the United States. A huge mass of molten rock is creeping upwards beneath the nation’s north eastern states.
“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 Rutgers University geophysicist Professor Vadim Levin.
Traces of the brooding mass only became evident through a large-scale new seismic study. The region is geologically stable. There are no active volcanoes. So the massive magma build-up must be a relatively recent event.
“It will likely take millions of years for the upwelling to get where it’s going,” Professor Levin explains. “The next step is to try to understand how exactly it’s happening.”
