Alaska's Mount Spurr Volcano Alert Level Reduced to Normal
Officials have lowered the alert level for Mount Spurr volcano near Alaska’s largest city to normal, indicating it is 'quiet' months after signs of activity raised eruption possibilities. The Alaska Volcano Observatory reported decreased unrest since March with no ground deformation detected. They characterize near-term eruption chances as 'extremely low,' noting continued small earthquakes and volcanic gas emissions are normal for volcanoes with magma moving upward without erupting. Mount Spurr, active within the last 250 years, has two vents: the last summit eruption was over 5,000 years ago, while Crater Peak had eruptions in 1953 and 1992. In October, the observatory raised alert status to yellow due to increased seismic activity, but has since returned to normal.
