Geologists monitor increased earthquake activity at Mount Spurr near Anchorage

Geologists are monitoring increased seismic activity at Mount Spurr, a volcano located about 80 miles northwest of Anchorage, Alaska. This year, around 1,500 small earthquakes have been recorded, compared to about 100 in a typical year. The Alaska Volcano Observatory raised the alert level for Mount Spurr from green to yellow in October due to this activity and observed ground deformation. While the current seismic unrest could indicate a potential eruption, scientists note that similar patterns occurred from 2004 to 2006 without an eruption. Mount Spurr last erupted in 1992, causing significant ash fallout that disrupted air travel. The volcano is one of 53 in Alaska that have been active in the last 250 years, and its activity is being closely monitored for any signs of an impending eruption.
