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

Tomorrow, April 6, a severe easterly blizzard will arrive with snowfall, followed later by rain and rising temperatures in the afternoon. The ground is frozen and there is considerable snow in the mountains that will melt during this thaw, which may cause rivers and streams to rise rapidly due to meltwater. Slush avalanches and wet snow avalanches may fall from gullies, and slopes will become unstable as thawing begins. Precipitation intensity will be highest in South Iceland near the glaciers. An ice jam in the Héraðsvötn river could break loose and cause flooding near the main road. Travelers are advised to proceed with caution and follow advises from authorities.

Magma volume beneath Svartsengi has never been greater since the start of the eruption sequence - 17.3.2026

Land Ground uplift and magma accumulation continue at a similar rate as in recent weeks, with magma inflow slow but steady. According to model calculations, more than 23 million cubic meters of magma have now accumulated beneath Svartsengi since the last eruption in July of last year. Magma accumulation beneath Svartsengi has never been greater since the beginning of this eruption sequence. Read more

The weather in Iceland in 2025 - 4.2.2026

The year 2025 was the warmest year in Iceland since measurements began. The national average temperature was 5.2 °C, which is 1.1 °C above the average for the years 1991–2020 and the highest ever recorded.

Overall, the weather in 2025 was unusually calm, with few stormy days and generally favourable conditions. It was relatively wet at the beginning of the year but dry toward the end. Snow cover was light across the entire country.

SeisComP becomes the new primary earthquake monitoring system of the Icelandic Meteorological Office - 3.2.2026

The implementation of SeisComP represents a major step forward in the development of the IMO's earthquake monitoring capabilities. Preparations have been underway for several years, and the system transition involves both technical and procedural changes aimed at improving analytical capability, data dissemination, and providing a more modern working environment for specialists.

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.
