A volcano near Anchorage, Alaska is showing signs of increased activity, but the Alaska Volcano Observatory (AVO) says an eruption is not imminent. Mount Spurr has been experiencing unrest for nearly a year, with increased earthquake activity and surface deformation. The AVO monitors the volcano closely, using 11 seismic stations to track its activity.
New gas measurements collected on February 7 show no significant changes from those taken last year, which were similar to background levels. According to Matthew Haney, AVO Scientist in Charge, this indicates that the unrest is not yet a clear sign of an impending eruption.
Haney notes that Mount Spurr has a history of explosive eruptions, but says the current activity leads him to believe that if an eruption were to occur, it would again come from the crater rather than the summit. The AVO is watching for signs of magma buildup and continuous earthquakes, which could indicate increased volcanic activity.
The main concern with an eruption from Mount Spurr is the potential impact on aviation and travel in the Cook Inlet region. Ash clouds and ashfall could affect air travel, and winds would dictate the direction of the ash cloud. The AVO monitors this volcano closely, along with dozens of others around the clock, to provide updates and research on volcanic activity.
