Specialist remark

An earthquake swarm began yesterday around 17:00, approximately 20 km west-southwest of Eldey on the Reykjanes Ridge. The largest earthquake recorded measured M3.4. More than 130 earthquakes have been recorded in the swarm so far. Earthquake swarms are common on the Reykjanes Ridge.

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

Electrical conductivity has been measured quite high for the last few days, about 260 microS/cm as well as CO2 and H2S gas being measured in Láguhvolar. This indicates that geothermal water is present in the river. The gas pollution can be dangerous to those staying near the river and thus travelers are urged to exercise caution and stay away from the riverbanks.

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

Situation on the Reykjanes Peninsula - 30.9.2026

Slow ground uplift continues at Svartsengi. Seismic activity remains low. A new magma intrusion, potentially leading to an eruption along the Sundhnúkur crater row, remains the most likely scenario. The updated hazard assessment takes account of fracture repairs in Grindavík. Read more

Increased electrical conductivity and gas pollution at Múlakvísl - 1.9.2026

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

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

Early work and an overview of measurements

Evaluation of the history of climate in Iceland since the settlement has been ongoing for more than two hundred years. Hannes Finnsson, the bishop of Skálholt wrote the first scientific treatise on the subject in 1796 (Finnsson, 1796).
