For years, scientists have wondered why North America’s highest mountain is not a volcano. All the ingredients for volcanic activity lurk deep beneath Denali, which sits above where one planetary plate grinds past another. Recently, while looking for something else, researchers found a reservoir of what might be magma, 7 miles beneath the muskeg of […]
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 […]
