A volcano near Alaska’s largest city could erupt in the coming weeks or months, scientists say

A volcano near Alaska’s largest city is showing new signs of unrest, with experts saying the likelihood of an eruption at Mount Spurr in the next few weeks or months has increased. The Alaska Volcano Observatory says it measured during recent overflights elevated volcanic gas emissions. It says an eruption is likely, though not certain, in the weeks ahead. Mount Spurr is one of 53 volcanoes in Alaska that have been active within the last 250 years. It is roughly 80 miles northwest of Anchorage. It last erupted in 1992, when it deposited ashfall up to about a quarter-inch thick in Anchorage and prompted temporary airport closures. A volcano near Alaska’s largest city is showing new signs of unrest, with experts saying the likelihood of an eruption at Mount Spurr in the next few weeks or months has increased.
