Specialist remark

Eruption started on Sundhnúksgígaröð NE of Stóra Skógfell at 03:54 the 16th of July. High levels of gas pollution have been measured in Reykjanesbær today. Gas has also been detected on Snæfellsnes and in the Westfjords this evening.

The eruption is still ongoing but activity has decreased in the Southern part of the fissure in the afternoon/evening. Poor visibility is in the eruption area and therefore difficult too see much.

On July 16th at 12:44, an earthquake of magnitude 3.1 occurred in Bárðarbunga, and then again at 14:07 another one of magnitude 3.0 occurred. Earthquakes of this magnitude are common in Bárðarbunga.

Week overview -

Earthquake activity throughout the country is described in a weekly summary that is written by a Natural Hazard Specialist. The weekly summary is published on the web every Tuesday. It covers the activity of the previous week in all seismic areas and volcanic systems in the country. If earthquake swarms are ongoing or significant events such as larger earthquakes have occurred during the week, they are specifically discussed. More

Remarks of a specialist

Increased run-off from glaciers is expected today and in the coming days due to warm temperatures. Travelers are advised to show caution around glacial rivers and to keep in mind that fords and rivers can become impassable.

Due to malfunction we have turned off the service publishing hydrological data on the map. Instead see the data using our Real-time monitoring system.

An eruption has started on Sundhnúksgígaröð crater row - 16.7.2025

Updated at 17:30

The hazard assessment map has been updated. The eruptive fissure at Sundhnúksgígaröð has lengthened while lava flow has decreased. Seismic activity and tremor have declined, but gas pollution and wildfires remain ongoing.

Heavy thunder and lightning in Northwest Iceland and the Westfjords - 16.7.2025

Continued Uplift in Svartsengi - 15.7.2025

Update July 15

Uplift and earthquake activity are ongoing in the Svartsengi area, with stable activity levels in recent weeks.

No substantial changes have been detected in measurements that would prompt a reassessment of the hazard level. However, continued magma accumulation could increase the likelihood of a magma intrusion or volcanic eruption in the coming autumn.

Analysis: Climate change made the May heatwave more likely and more intense - 11.6.2025

In May 2025, an unusually intense heatwave struck Iceland and eastern Greenland, breaking numerous temperature records. On 15 May, Iceland's national May temperature record was set at 26.6°C at Egilsstaðir Airport, with several locations recording temperatures up to 13°C above the monthly average.

A new international analysis by the World Weather Attribution group shows that human-induced climate change made this heatwave around 40 times more likely and, on average, three degrees Celsius hotter than it would have been without global warming. The study also suggests that if global temperatures rise by 2.6°C, such heatwaves could become at least twice as frequent and two degrees hotter.
