Magma beneath long-dormant Mount Edgecumbe volcano in Southeast Alaska has been moving upward through Earth’s crust, according to research the Alaska Volcano Observatory rapidly produced using a new method.

The new approach at the observatory could lead to earlier detection of volcanic unrest in Alaska.

At Mount Edgecumbe, computer modeling based on satellite imagery shows magma is rising to about 6 miles from a depth of about 12 miles and has caused earthquakes and significant surface deformation.

“That’s the fastest rate of
