ANCHORAGE, Alaska – An Alaskan volcano that hasn’t erupted in more than 30 years is showing some increasing signs of seismic life, though volcanologists still say it doesn’t mean an eruption ...
Mount Katmai is one of five vents encircling the Novarupta volcano, source of the VEI 6 eruption and associated voluminous pyroclastic flows in 1912. Katmai consists chiefly of lava flows, pyroclastic rocks, and non-welded to agglutinated air fall. The Quaternary volcanic rocks at Katmai and adjacent cones are less than 5,000 ft (1,500 m) thick.
Not one but two volcanoes on the same island in Alaska’s Aleutian chain were rocked by earthquakes on Friday, prompting concerns about a possible eruption. Elevated earthquake activity was ...
