The data showed that magma is rising in a United States volcano that’s been long dormant about 6 miles from a depth of about 12 miles.
It has caused significant surface deformation, according to researchers.
“That’s the fastest rate of volcanic deformation that we currently have in Alaska,” said the research paper’s lead author, Ronni Grapenthin, a University of Alaska Fairbanks associate professor of geodesy.
It's also unusual.
“And while it is not uncommon for volcanoes to deform, the activity at Edgecumbe is unusual because reactivation of dormant volcanic systems is rarely observed,” he added.
