The Alaska Volcano Observatory (AVO) has issued a warning over concerns that an eruption at Mount Spurr may be imminent.
AVO warns that an active volcano on Mount Spurr could soon erupt after 73 earthquakes struck the area over the previous week.
An imminent eruption could cause the evacuation of 300,000 residents in Anchorage, 80 miles away.
Residents could be in danger from its effects, AVO said.
Those who don’t evacuate may have to wear N95 masks due to the pollution.
Residents are being urged to stockpile food and water in preparation.
In addition, flights over the area could be halted because of visibility concerns from the volcanic ash cloud that would result from an eruption.
Besides the 73 recorded earthquakes, “much smaller quakes are occurring several times per hour,” the observatory said.
Steam has been seen rising from the volcano along with increased gas emissions.
Magma rising toward the surface is also causing pressure and fractures in the rock that surrounds it.
The level of unrest at the volcano is somewhat lower than a few months ago, but remains elevated.
“Unrest continues at Mount Spurr, though at a lower level than observed in early 2025,” AVO said.
