Alaska's Mount Spurr Volcano Shows Signs of Possible Eruption

Scientists report increased seismic activity, gas emissions, and magma movement, suggesting an eruption could occur within weeks or months.

Mount Spurr, located 80 miles northwest of Anchorage, has shown significant volcanic unrest, including elevated gas emissions and reactivated vents.
Magma has been accumulating beneath the summit for months, with new pathways forming near the Crater Peak vent, increasing the likelihood of an eruption.
More than 3,400 earthquakes have been detected in the area since April 2024, alongside ground deformation and surface heating.
Previous eruptions in 1953 and 1992 produced massive ash clouds, temporarily closed airports, and caused ashfall in south-central Alaska.
Authorities caution that an eruption, if it occurs, could disrupt air traffic, impact water supplies, and pose health risks from volcanic gases and ashfall.
