Monitoring and official alerts
PocketWorld combines this stable catalog record with available public hazard context. The reference status is not a prediction or a live observatory alert. For current unrest, aviation color codes, exclusion zones and eruption notices, use the responsible volcano observatory and civil-protection authority.
How to interpret the Yellowstone record
Yellowstone is cataloged as a Supervolcano in Wyoming, USA, with a reference elevation of 2805 metres. This page combines stable geographic facts with available hazard context. A general status label does not predict the timing, size or location of future activity and may not use the same scale as the responsible observatory.
Check the latest observatory bulletin, aviation notice and civil-protection guidance before making travel or safety decisions. PocketWorld provides a map and source path, not an eruption forecast or exclusion-zone authority.
Hazard data sources
Events are aggregated from USGS, EMSC, NOAA, NASA EONET, NASA FIRMS and GDACS, then normalized and deduplicated.
