Volcano near Anchorage, Alaska could erupt in weeks or months

The likelihood of an eruption in the next weeks or months at Mount Spurr, a volcano near Alaska’s largest city of Anchorage, has increased, according to volcanologists.

Significantly elevated volcanic gas emissions were detected during overflights of Mount Spurr, according to the Alaska Volcano Observatory (AVO). Additionally, newly reactivated gas vents were observed at the volcano’s Crater Peak vent, alongside continued earthquake activity and ground deformation.

The observatory stated that further increases in seismic activity, gas emissions, and surface heating are expected before an eruption, potentially providing days to weeks of additional warning.

The only recorded historical eruptions of Mount Spurr occurred in 1953 and 1992 from the Crater Peak flank vent, located two miles south of the peak’s summit. These eruptions were explosive, producing ash columns that rose as high as 65,000 feet above sea level, depositing volcanic ash across Anchorage.

If an eruption occurs, the USGS warns that trans-Pacific and trans-Arctic air routes could face severe disruptions. During the 1992 eruption, Anchorage International Airport was forced to suspend operations due to significant ashfall.
