Alaska’s Mount Spurr volcano is showing signs of increased activity, with small earthquakes, ground swelling, and melting snow indicating potential unrest. Experts estimate a 50% chance of eruption, though the timeframe remains uncertain.
The last major eruption in 1992 caused ashfall in Anchorage and temporarily shut down the airport. While scientists closely monitor seismic activity, past episodes of unrest in 2004 and 2012 did not lead to eruptions.
With its proximity to Alaska’s most populated city, Mount Spurr remains a high-risk volcano. Researchers continue to assess potential gas emissions and seismic patterns to determine if an eruption is imminent.
