Increased Seismic Activity: Dozens of mini-earthquakes, including “swarms,” have been recorded at Mount Spurr, indicating rising magma and increased pressure.
Eruption Threat: Scientists fear a major eruption is imminent due to the increased seismic activity and elevated gas emissions.
Potential Ash Cloud: An eruption could be explosive, with ash plumes reaching up to 50,000 feet. Each explosive event may last 3-4 hours.
Anchorage on Alert: Anchorage, with over 300,000 residents, is on emergency alert (Level 2) and is located 81 miles from the volcano.
Community Preparedness: Residents are stocking up on essentials like food, water, pet supplies, N95 masks, and protective gear.
Rising Unrest: Concerns began in April 2024, with a significant increase in weekly quakes and gas emissions by October 2024.
Gas Emissions: Elevated carbon dioxide and sulfur dioxide emissions signal magma heating water and gas below the surface.
Volcanic Tremor as Indicator: Sustained volcanic tremor would be the next sign of an imminent eruption.
Last Eruption Impact: The 1992 eruption from Crater Peak (a side vent) blanketed Anchorage in ash and shut down the airport.
Most Likely Eruption Site: Experts expect the next eruption to likely occur from Crater Peak again.
Pet Preparedness: Pet stores are experiencing high demand for protective goggles and respirators for pets.
Monitoring: The National Transportation Safety Board and US Geological Survey are closely monitoring the volcano.
