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 - 12.5.2026

Ground uplift and magma accumulation continue beneath Svartsengi, with over 25 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

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.

Climate change and hydrology: Environmental and societal effects

The climate and hydrology of Iceland are highly variable due to natural conditions. Significant changes in these factors over the last 15 years are in harmony with the future scenarios represented and affirmed in the latest IPCC summary report, AR5. The main purpose of IMO is to contribute towards security in society by monitoring, analyzing, interpreting, informing; providing warnings and forecasts and predicting natural hazards. It is important to keep the infrastructure strong so that IMO may fulfill its role.
