Mount Spurr, a massive volcano located approximately 80 miles from Anchorage, Alaska, has experienced a surge in seismic activity, with 73 earthquakes recorded in the past week alone.

According to the Daily Mail, The Alaska Volcano Observatory (AVO) reported on Friday that the volcano remains at an elevated level of unrest, warning that an explosive eruption could occur in the coming weeks to months.

In addition to the significant tremors, countless smaller quakes are occurring several times per hour, indicating that magma is rising toward the surface, fracturing surrounding rock and creating intense pressure.

Beyond seismic activity, AVO scientists have observed steam rising from the volcano and increased gas emissions, further evidence of its restless state.

While ground deformation has slowed over the past month, it had previously intensified in November and December 2024 before resuming.

The AVO noted, “Unrest continues at Mount Spurr, though at a lower level than observed in early 2025. While the likelihood of an eruption has decreased since March, the volcano remains at an elevated level of unrest.”

Experts predict that any eruption would mirror the volcano’s past events in 1953 and 1992, which featured explosive bursts lasting several hours.

These eruptions produced ash clouds that traveled hundreds of miles and deposited up to a quarter inch of ash across southcentral Alaska.

Each explosive episode is expected to last three to four hours, potentially blanketing Anchorage—a city of nearly 300,000 residents—and nearby communities with a thick layer of volcanic ash.

An eruption would also trigger destructive mudslides and avalanches of volcanic debris, racing down the volcano’s slopes at speeds exceeding 200 miles per hour.

Fortunately, no communities lie within the immediate danger zone, according to AVO scientist Matt Haney.

With Mount Spurr on advisory status since last fall, Anchorage residents are actively preparing for a possible eruption.

Stockpiling supplies has become a priority as the city braces for the potential fallout of volcanic ash, which could disrupt daily life and infrastructure.

The eruption’s impact would extend far beyond Anchorage. A massive ash cloud could force the closure of major transportation hubs, including Ted Stevens Anchorage International Airport (ANC) and potentially Fairbanks International Airport (FAI).

Such closures would halt all incoming and departing flights, causing widespread delays and cancellations across the country and potentially disrupting the global supply chain.

Transportation systems are already scrambling to prepare for the international chaos an eruption could unleash.

As Mount Spurr continues to rumble, Alaska remains on high alert. While the immediate threat to human life is limited due to the absence of communities near the volcano’s base, the broader consequences of an eruption could be profound.

With Anchorage and its surrounding areas at risk of being blanketed in ash and critical infrastructure facing significant disruptions, the region is preparing for a natural event that could reshape daily life and ripple across the globe.
