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

Hydrology

Remarks of a specialist

A glacier outburst flood in Skaftá river is receding and the discharge is now around 60 m3/s at Sveinstindur. Conductivity has been decreasing and is now being measured at 370 µS/cm. This suggests that floodwater is still reaching the river. Important to take caution at the river's outlet due to gas pollution.

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 - 11.12.2025

Updated 25 November

The rate of magma accumulation beneath Svartsengi has remained fairly stable over the past two weeks. The likelihood of a magma intrusion and an eruption remains elevated in the coming weeks. The hazard assessment remains unchanged until 9 December

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.

A jökulhlaup from Mýrdalsjökull into the rivers Leirá Syðri and Skálm - 11.7.2025

The flood is subsiding, and water level and conductivity are now approaching normal values in Skálm.

The flood reached its peak the night before last. IMO´s specialists continue to observe the area

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.
