U.S. Geological Survey Expands Volcano Updates to Enhance Public Monitoring

U.S. Geological Survey operates the Volcano Hazards Program website that hosts the Volcano Updates page, serving as a central hub for current status reports on all active volcanoes across the United States, including eruption summaries and alert information.

Volcano Updates page lists each volcano’s alert level, recent eruption activity, and any issued warnings, and provides brief descriptions of observed phenomena such as ash plumes or lava flows, allowing communities and emergency officials to assess risk in real time.

Public Access to the updates is free and available online, supporting scientists conducting research, educators teaching geology, and residents living near volcanic zones who rely on timely information for preparedness, evacuation planning, and ongoing community awareness.

Monitoring Network includes dozens of seismic stations, satellite imagery analysis, and regular field observations by volcanologists, ensuring that displayed alerts reflect the latest data from multiple sources and that changes are captured promptly.
