Mount Edgecumbe Volcano Update; Magma is Moving at Depth, Uplift Detected

The Mount Edgecumbe volcano near the town of Sitka in Alaska is showing signs of unrest, as magma has been detected moving underneath its edifice. This generated a series of several hundred earthquakes which are centered to the east of the peak of Mount Edgecumbe. Mount Edgecumbe has not produced an eruption in more than 4,000 years, so these shallow earthquakes are quite unusual and a bit worrying. More analysis is being done to determine the cause of these quakes, and if an eventual eruption is a possibility.
