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.”

Scientists from the Alaska Volcano Observatory have reported significant unrest at Mount Spurr, an 11,070-foot volcano located approximately 80 miles northwest of Anchorage, Alaska, indicating a potential eruption in the coming weeks or months,
