U.S. Volcanoes on High Alert: Scientists Monitor Great Sitkin, Mount Spurr, and Kilauea
Three U.S. volcanoes—Alaska’s Great Sitkin and Mount Spurr, and Hawaii’s Kilauea—are showing signs of rising volcanic unrest. Earthquake swarms, ground deformation, and gas emissions suggest magma is moving closer to the surface, raising eruption risks.
-
Great Sitkin is now at “Watch” status, following lava emissions and increased seismic activity.
-
Mount Spurr, near Anchorage, has seen earthquakes surge from 30 to 125 per week since April 2024. Scientists estimate a 50/50 chance of eruption.
-
Kilauea erupted for the 9th time since December 2024, sending lava 300 feet into the air. So far, no homes are threatened, but toxic gases and ash remain a concern.
What’s at Stake?
These volcanoes pose risks to nearby communities, air travel, and infrastructure. Volcanologists are using satellite imagery, gas sensors, and seismic monitors to predict potential eruptions and issue timely warnings.
Who’s at Risk?
-
Aleutian Islands (Great Sitkin) – ashfall and air traffic disruption.
-
Anchorage (Mount Spurr) – power outages, poor air quality, travel issues.
-
Hawaii Volcanoes National Park (Kilauea) – lava flows, gas exposure, possible evacuations.
Bottom Line:
The situation is evolving. While no eruptions are guaranteed, officials urge residents to stay informed, prepare emergency plans, and follow updates from geological agencies.
