The Alaska Volcano Observatory said signs indicated a Mount Spurr eruption was likely, though not certain, in the weeks or months ahead.

“It is also possible that an eruption could occur with little or no additional warning,” the Alaska Volcano Observatory stated. “This would be extremely hazardous for recreators on Mount Spurr or near its drainages as well as those overflying the volcano.”

Alaska’s Mount Spurr, a snow-covered volcano 75 miles outside Anchorage, is showing signs it could erupt soon, experts warned. Scientists at the Alaska Volcano Observatory said the volcano will likely erupt in the coming weeks or months,
