Scientists have issued warnings about potential volcanic eruptions at two sites in the United States, including one near Anchorage, Alaska. Mount Spurr, approximately 80 miles west of the city, has been exhibiting heightened volcanic gas emissions, as reported by the Alaska Volcano Observatory (AVO) earlier this week. Recent aerial surveys over the volcanic mountain have documented this increased activity.
The AVO communicated that elevated seismic activity, gas emissions, and surface heating might precede an eruption, though such changes are not definitive indicators. An eruption can also occur without prior warning, making it particularly dangerous for those near the area or flying over it.
Meanwhile, Mount Adams, in Washington state, is also under closer scrutiny, as it experienced a series of minor earthquakes toward the end of last year. The 12,000-foot volcano poses a significant risk due to the potential for landslides and mudslides, particularly affecting residents in South Central Washington.
Although the uptick in seismic events around Mount Adams does not definitively predict an imminent eruption, it is notable. According to the U.S. Geological Survey (USGS), nine earthquakes ranging from magnitude 0.9 to 2.0 were recorded near the volcano between September and October 2024. Typically, this area experiences only one quake every two to three years.
According to USGS, the principal threat is the risk of avalanches and landslides—phenomena capable of sending rock, ash, and ice down the mountain, irrespective of eruptive activity. Though the frequency of seismic events around Mount Adams has diminished since October, experts remain vigilant for any resurgence.
