Hot Rocks by Shannon Hall

For the past 200 million years, New England has been a place without intense geological

change. With few exceptions, there have been no rumbling volcanoes or major earthquakes, but it might be

on the verge of awakening. Findings published this January in the journal geology show a bubble of

hot rock rising underneath the northern Appalachian

Mountains. The feature was first detected in 2016 by Earthscope, a collection of thousands of

seismic instruments sprinkled throughout the U.S. Vadim Levin, a geophysicist at Rutgers University,

says this wealth of sensors lets Earth scientists peer under

the North American continent, just as the Hubble Space Telescope has enabled astronomers to gaze

deep into the night sky. Should the broiling rock breached the surface, which could happen,

though not until tens of millions of years from now, it would transform New England

into a burbling volcanic landscape. The finding has sparked many questions given that New

England is not located along an active plate margin, where one tectonic plate rubs against another,

but sits squarely in the middle of the North American plate. The exact source of the

hot rock bubble, for example, is unclear. Because the edge of the North American continent is

colder than a plate near an active margin, Levin suspects this edge is cooling the mantle, the layer
