Anchorage, AK – Officials are warning that nearly half of Alaska’s population could be affected if Mount Spurr erupts in the coming days, prompting a regional alert for south-central Alaska, including Anchorage.
According to the Alaska Volcano Observatory, seismic activity at the volcano has increased, raising the likelihood of an eruption. Mount Spurr, located about 80 miles west of Anchorage, last erupted in 1992, sending ash nearly 50,000 feet into the air and forcing the Anchorage airport to close for 20 hours. The volcano’s previous eruptions in 1953 and 1992 caused widespread ashfall across the region.
If Mount Spurr erupts again, volcanic ash could reach towns like Beluga, Nikiski, Tyonek, Susitna, and Salamatof. The observatory warned that ash can damage vehicles, impact lungs and eyes, and disrupt air travel. Residents are encouraged to stay indoors and wear masks if ash is present.
While the area immediately surrounding the volcano is uninhabited, Mount Spurr is a tourist destination. Authorities urge visitors to monitor conditions and sign up for the Volcano Notification Service.
The timing and severity of any ashfall will depend on weather and eruption strength. Officials stress that residents should stay prepared through the end of the week.
