Increased Likelihood of an Eruption is ongoing on the Sundhnúkur Crater Row - 23.12.2025

Updated 23 December 

Magma accumulation beneath Svartsengi remains slow but steady, as it has in recent weeks. As long as magma accumulation continues, the likelihood of a dike intrusion and volcanic eruption remains elevated; however, uncertainty regarding the timing of the next eruption increases when magma accumulation is slow. Given the current rate of accumulation, the uncertainty in timing spans several months.

The ninth eruption on the Sundhnúkur crater row has ended - 5.8.2025

Updated 5 August

The volcanic eruption that began on 16 July on the Sundhnúkur crater row is now officially over, and a new hazard map has been issued. Despite the end of the eruption, life-threatening conditions remain in the area due to unstable lava and the potential for gas pollution. Uplift has resumed, and magma continues to accumulate beneath Svartsengi.

Eruption ongoing on the Sundhnúkur crater row - 15.7.2025

Updated at 11:30, 20 July

The eruption at the Sundhnúkur crater row has caused significant air pollution in recent days, with volcanic haze spreading widely but not fully captured by the national air quality monitoring network. The Icelandic Meteorological Office forecasts gas pollution in South and West Iceland over the coming days, with light winds contributing to persistent haze, especially in the southwest. Vulnerable groups are advised to limit time outdoors if they experience discomfort, and practical guidance for reducing indoor exposure is provided.

Eruption at the Sundhnúkur crater row remains likely - 25.3.2025

Updated 25. March at 15:00 UTC

GPS deformation data shows that magma continues to accumulate beneath Svartsengi, although the pace of land uplift has slightly decreased in recent weeks. Despite the slower uplift, experts still consider it likely that a magma intrusion and/or eruption will occur along the Sundhnúkur crater row.

Gas pollution forecast, distribution model and registration form for gas pollution.

Below is a text forecast regarding gas pollution from the eruption in Fagradalsfjall. At the bottom of the page is a forecast model showing sulfur pollution (SO2) in inhabited areas for the next 48 hours.

The first map shows the level of pollution at ground level. The other three maps shows an impact forecast for the next 6hrs and 24hrs. These maps indicate areas, not level of pollution.

Important information about gas pollution for people in the volcanic hazard zone:

  • Gas pollution can always reach unhealthy levels near the eruption zone. The gas plume is advected down wind.
  • In calm wind conditions (< 5 m/s) the distribution of gas pollution can become unpredictable, as the heat from the lava field can affect wind direction in the area.
  • The lava field also produces gas pollution because of degasification.
  • If you experience symptoms it is important to leave the polluted area.
