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

Southerly storms are expected over the coming days, with mild temperatures, thawing, and considerable rain. With the combination of warm temperatures and heavy precipitation, there is a risk of rising water levels in rivers and streams as well as possible flooding around watercourses, especially in the south and west parts of the country. Special warnings are issued for landslides.

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.

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.

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

By 11:00, more than 450 lightning strikes had been recorded since the activity began.

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.

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.
