Mount Spurr Volcano Nearing Eruption: Alaska on Alert

Increased seismic activity at Alaska’s Mount Spurr has prompted warnings that the 11,000-foot volcano, located 81 miles from Anchorage, may be nearing an eruption. Experts from the Alaska Volcano Observatory (AVO) report hundreds of small earthquakes, ground deformation, and elevated gas emissions—signs of rising magma beneath the surface.
Rising Unrest
Since April 2024, seismic activity near Mount Spurr has escalated, with weekly earthquakes jumping from 30 to 125 by October. A magnitude 3.7 quake struck near Petersville on April 2, marked by an unusual depth of 65 miles—potentially linked to magma movement. While most deep quakes relate to tectonic shifts, AVO suggests this activity could signal volcanic unrest.

Eruption Risks
The volcano’s Crater Peak vent, last active in 1992, is the probable source of any eruption*. AVO scientist Matt Haney warns an explosion would send ash plumes up to 50,000 feet, paralyzing air travel and coating Anchorage in hazardous dust. Fast-moving debris avalanches (over 200 mph) may also occur, though no nearby communities lie in their path.
1992 Eruption: A Blueprint
In 1992, three eruptions from Crater Peak darkened skies, forced a 20-hour airport shutdown, and left Anchorage under 0.5 inches of ash. Cleanup cost nearly $2 million, with health impacts including fatal heart attacks from ash removal efforts. Fine ash particles pose respiratory risks, particularly for those with asthma or bronchitis.

Preparedness Underway
On March 20, Anchorage elevated its alert to Level 2, initiating emergency protocols. The AVO monitors for volcanic tremors—a key eruption precursor—using seismic networks and satellite data. While timing remains uncertain, eruptions could begin within “weeks or months.”
Conclusion
Mount Spurr’s volcanic system, mostly dormant for millennia, now shows clear agitation. Scientists urge preparedness, recalling 1992’s disruptions. As Anchorage braces, the AVO continues 24/7 monitoring to provide advance warnings.
