Mount Spurr Volcano Showing Signs of Potential Eruption Mount Spurr in Alaska is showing signs of unrest, with over a dozen small earthquakes recorded nearby, the largest being magnitude 3.1. A steam plume was recently seen rising from the 11,000-foot volcano, likely caused by magma heating underground water. Although seismic activity remains high, the Alaska Volcano Observatory (AVO) reports no current signs of an imminent eruption. Ground deformation has slowed, and crater ice remains intact. If it erupts, Mount Spurr could send ash plumes 50,000 feet high, disrupt air travel, and cause ashfall in Anchorage, 78 miles away. The 1992 eruption shut down Anchorage’s airport for 20 hours and caused $2 million in damages. AVO continues to monitor the volcano closely, watching for volcanic tremors that would signal escalating activity
