It last erupted in 1992 and had a devastating impact!

Mount Spurr, a 11,070-foot stratovolcano west of Anchorage, Alaska, is showing troubling signs after decades of silence. Over 3,400 earthquakes have been recorded beneath it in the past year, suggesting rising magma. In just February and March alone, over 100 tremors struck weekly.

The Alaska Volcano Observatory is closely monitoring the situation, using seismic data, satellite imagery, and gas readings. This level of activity mirrors patterns seen before Mount Spurr’s 1992 eruption, which disrupted air travel and covered Anchorage in ash.

Residents are preparing, buying masks and air purifiers, sealing windows, and assembling emergency kits. Volcanic ash, if it returns, can irritate lungs, damage engines, and make driving hazardous.

While scientists can’t predict when an eruption might occur, the warning signs are clear. For now, Alaskans remain on high alert, balancing calm readiness with caution. The mountain may still be quiet—but it’s being closely watched.
