FfFfFfFF 58,378 Posted December 9, 2020 Share Posted December 9, 2020 A trail of volcanic islands off the coast of southern Alaska may actually be part of a single giant caldera, according to evidence being presented next week at the American Geophysical Union’s fall meeting. If so, it’s possible the newly revealed volcanic giant once erupted in a blast large enough to dwarf the cataclysmic 1980 eruption of Mount St. Helens. The behemoth in question is marked by a semi-circular cluster of peaks in the Aleutian Islands known as the Islands of the Four Mountains (IFM). Long thought to be independent volcanoes, the six peaks—including Herbert, Carlisle, Cleveland, Tana, Uliaga, and Kagamil—may actually be a series of connected vents along the edge of a much larger volcanic caldera. Even if the idea is confirmed, though, the results don’t necessarily foretell of future catastrophe. “This new research result doesn’t change the hazards,” says John Power, a geophysicist at the U.S. Geological Survey and the Alaska Volcano Observatory who will present the work Monday at the AGU meeting. “We’re not forecasting something dangerous here.” https://www.nationalgeographic.com/science/2020/12/alaska-islands-may-be-part-single-massive-volcano/ Link to post Share on other sites More sharing options...
