Recent observations indicate heightened activity at three U.S. volcanoes: Alaska’s Great Sitkin and Mount Spurr, and Hawaii’s Kilauea. These developments have prompted scientists to closely monitor potential eruption risks.
Great Sitkin Volcano, Alaska
Great Sitkin has been experiencing a slow eruption of lava within its summit crater since July 2021. The Alaska Volcano Observatory (AVO) reports ongoing low-level seismic activity, with small earthquakes detected beneath the volcano. The volcano remains at an elevated alert level due to this persistent activity.
Mount Spurr, Alaska
Mount Spurr, located approximately 75 miles west of Anchorage, has shown elevated seismicity with numerous small, shallow volcanic earthquakes detected beneath the volcano. While no eruptive activity has been observed, the increased seismicity warrants close monitoring.
Kilauea Volcano, Hawaii
Kilauea continues its active phase, with the latest eruptive episode producing lava fountains in the Halemaʻumaʻu crater. This marks the 12th eruptive episode since December 23, 2024. Lava fountains have reached heights between 30 and 165 feet, attracting visitors to Hawaii Volcanoes National Park. Officials caution about hazardous gases like sulfur dioxide and minor volcanic-ash emissions.
Monitoring and Preparedness
Scientists utilize advanced monitoring tools, including seismic sensors, satellite imagery, and gas emission analyses, to track these volcanoes’ activity. Communities near these volcanoes are advised to stay informed and prepared for potential volcanic events, as conditions can change rapidly.
