What an active-volcano marker means
Volcano records combine reference locations with available observatory notices and recent hazard reports. The presence of a volcano on the map does not mean that it is erupting now, and a quiet marker does not guarantee that local risk is low. Monitoring networks, alert scales and reporting schedules differ by country.
Open the source notice for the latest status, aviation color code and exclusion guidance. PocketWorld provides geographic context and links to evidence; it does not predict eruptions or replace a volcano observatory or civil-protection authority.
The reference catalog also includes historically active systems so visitors can understand their location before reading a current observatory assessment.
Hazard data sources
Events are aggregated from USGS, EMSC, NOAA, NASA EONET, NASA FIRMS and GDACS, then normalized and deduplicated.
Frequently asked questions
Does every marker represent a current eruption?
No. The map combines stable reference locations with available recent reports. Presence on the map does not mean a volcano is erupting now.
Where should I verify a current volcano alert?
Use the linked source and the responsible national or regional volcano observatory. Alert scales and reporting schedules differ by country.
