Volcanic alerts in Iceland today
No national alert status is shown because this country’s competent authority is not yet operationally connected to GDE.
EarthSentra does not issue its own volcano alerts. A volcano’s presence in the Smithsonian GVP catalog does not mean it is active, erupting, or under alert.

This hub highlights confirmed eruptions with VEI 3 or higher when available. Smaller or uncertain eruptions are not automatically presented as major events. The historical source is Smithsonian GVP.
Volcanic setting of Iceland
Iceland sits astride the Mid-Atlantic Ridge and is also influenced by a mantle hotspot. Volcanic zones on the Reykjanes Peninsula and around the central highlands have different types of activity. A listed volcano is not necessarily erupting, and its geological history should be distinguished from any official alert.
How to read this volcanic monitor
The map uses catalog information provided through EarthSentra’s integrated sources. Historical eruption entries reflect documented past events, sometimes with uncertain dates or missing Volcanic Explosivity Index values. They are not forecasts, and the history displayed may be a selection of the full scientific record.
Official alerts and safety information
Use the national geological and civil protection agencies for current hazard levels, exclusion zones and evacuation guidance. EarthSentra’s alert count includes only the monitoring feeds connected to its system; a zero count or missing national feed does not establish that the area is safe.
Additional sources
Consult the Smithsonian Global Volcanism Program for geological context and the global volcano monitor for a worldwide comparison. Always give priority to current local official warnings.
