Mount Spurr's impending eruption threatens Anchorage, Alaska

Scientists from the Alaska Volcano Observatory have reported significant unrest at Mount Spurr, an 11,070-foot volcano located approximately 80 miles northwest of Anchorage, Alaska, indicating a potential eruption in the coming weeks or months, reports NBC News.
Recent overflights have detected “significantly elevated volcanic gas emissions” and reactivated gas vents, suggesting magma intrusion beneath the summit. The observatory noted: “We expect to see further increases in seismic activity, gas emissions, and surface heating prior to an eruption if one were to occur.”
Mount Spurr’s Crater Peak vent last erupted in 1992, producing ash columns over 50,000 feet high and depositing ash across south-central Alaska, including Anchorage. These eruptions led to temporary airport closures and disrupted daily life.
Potential impact on Anchorage and surrounding areas
An eruption could result in significant ashfall in Anchorage and nearby communities, affecting air quality, aviation, and infrastructure. Volcanic ash is abrasive and can cause jet engines to fail, posing serious risks to air travel. The observatory cautioned that while an eruption is likely, it is not certain, and the situation is being closely monitored.
This development mirrors recent volcanic activity worldwide, such as the eruption of a long-dormant volcano in Iceland’s Reykjanes Peninsula, which led to significant disruptions and highlighted the need for preparedness in volcanic regions.
Residents and authorities in Alaska are advised to stay informed and prepare for potential ashfall and related impacts.
