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

Over the last few days, high electrical conductivity has been observed in the Múlakvísl river. At its highest it was around 270 µS/cm but is now around 150 µS/cm. Gas pollution is still being detected in the area, and travellers are advised to exercise caution and leave the area if they experience symptoms that could indicate exposure to volcanic gases.

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

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

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.

Avalanches in Iceland

Catastrophic avalanches in the villages Súðavík, 16 January 1995, and Flateyri, October 1995, which killed 34 people and caused extensive economic damage, totally changed the view regarding avalanche safety in Iceland.
