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

Ground uplift and magma accumulation continue beneath Svartsengi - 26.5.2026

Ground uplift and magma accumulation continue beneath Svartsengi, with about 26,6 million cubic meters of magma estimated to have accumulated since the last eruption. A dike intrusion and possible eruption along the Sundhnúkur crater row remain the most likely scenario. Read more

IMO expert to lead international collaboration on geohazards - 12.5.2026

Michelle Parks, a specialist in deformation measurements and volcano monitoring at the Icelandic Meteorological Office (IMO), has been elected Chair of GEO-GSNL, the Geohazard Supersites and Natural Laboratories initiative. She formally assumed the role on 7 May 2026. Read more

Nordic report on the impacts of a AMOC tipping urges stronger mitigation, monitoring and preparedness - 5.2.2026

The report A Nordic Perspective on AMOC Tipping reviews the current state of science on the impacts of potential Atlantic Meridional Overturning Circulation (AMOC) collapse and provides recommendations for policy actions.

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. Temperatures were well above average for almost every month of the year. The spring weather was exceptionally favourable; it was the warmest spring ever recorded nationwide, and May was by far the warmest May on record. In mid-May, a 10-day heatwave occurred across the entire country. It was the most significant heatwave known in Iceland for the month of May. 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.

HARMONIE - numerical weather prediction model

HARMONIE is a numerical weather prediction model (NWP) that is non-hydrostatic and convection-permitting. It is operated at 2.5 km horizontal resolution over a domain that covers Iceland and the surrounding seas. At this resolution it is possible to simulate explicitly some processes that are important for clouds and precipitation as well as meteorological phenomena related to up- and downdrafts. In order to simulate the interaction between the atmosphere and the surface, the model takes into account different types of land surface as well as processes in and at the surface.
