Specialist remark

Early this morning at 3:38am an earthquake of M4.5 was detected some 26 km WSW of Eldey on the North-Atlantic ridge. It was a trigger for a seismic swarm that is still ongoing. Last time an event of this magnitude was detected there was on March 23rd of this year.

The event is located on the North-Atlantic ridge due to tectonic movements there. Seismic swarms and earthquakes are regularly detected in this area.

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

A small glacial outburst flood began on the 23rd of August in the Jökulsá á Sólheimasandi river, it appears to be subsiding. This has happened a few times this summer in rivers by Mýrdalsjökull. Geothermal gasses could be noticed in the vicinity.

Due to malfunction we have turned off the service publishing hydrological data on the map. Instead see the data using our Rauntímavöktunarkerfi.

Increased discharge and significant gas pollution in Múlakvísl - 21.8.2026

The glacial outburst flood in Múlakvísl, which began on 18 August, now appears to be subsiding. Both conductivity and discharge have decreased since yesterday, and currently there is no gas pollution being detected in the area Read more

Situation on the Reykjanes Peninsula - 18.8.2026

Magma accumulation and ground uplift continue beneath Svartsengi. The average rate of magma accumulation over the past few weeks has remained steady.

The most likely scenario remains continued slow magma accumulation, eventually leading to a new dike intrusion and possibly a volcanic eruption.

Measurements show that uplift at Askja has ceased - 14.8.2026

Measurements by the lake in Askja. Fieldwork in the area was completed this week, and the results indicate that the uplift episode that began in 2021 has ended.

Increased hazard due to changing conditions at the margin of Sólheimajökull glacier - 22.7.2026

Recent changes at the terminus of Sólheimajökull call for increased caution. Unstable glacier ice and rockfall from the surrounding slopes may pose a risk to people visiting the area.

Ground uplift and magma accumulation continue beneath Svartsengi - 9.6.2026

Uplift and magma accumulation continue at Svartsengi, and the trend remains stable. The latest model calculations indicate that around 27.5 million cubic metres of magma have accumulated beneath Svartsengi since around mid-July last year. Read more

The Icelandic Met Office receives international grant to strengthen aviation safety in relation to volcanic hazards - 3.6.2026

In October 2025, the Icelandic Meteorological Office (IMO) received a grant of ISK 147 million from the International Civil Aviation Organization (ICAO) for four new development projects in the fields of volcanic hazards and aviation safety. The projects involve, among other things, the development of new measurement methods, automatic analysis of eruption plumes, coordination of responses among European volcano observatories, and research into the effects of sulphur dioxide (SO₂) on aviation.

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.
