An NSF-funded ashfall study links magma composition shifts to volcanic tremors, offering a powerful new tool for monitoring eruptions and protecting communities U.S. National Science Foundation-funded researchers discovered that subtle changes in magma composition may drive tremors during volcanic eruptions, offering a new tool for forecasting volcanic activity and guiding hazard assessments. Volcano forecasts are […]
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 […]
KANUTI HOT SPRINGS — After a few hours of skiing through deep snow, Forest Wagner and I smelled a tuna sandwich. We knew we were closing in on warm pools of water. From the frozen Kanuti River, we moved along an open stream up toward Kanuti Hot Springs, one of more than 100 hot springs […]
