Specialist remark

An earthquake swarm began around midnight on September 16th. Most earthquakes are located around 30 km SSW of Reykjanestá. The largest earthquake detected in this swarm was measured 3.4 in magnitude. 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

Situation on the Reykjanes Peninsula - 15.9.2026

Deformation measurements continue to show uplift in the Svartsengi area. Over the past three months, the land has risen by approximately five centimetres. The uplift indicates that pressure continues to build at a depth of several kilometres. As long as uplift continues, the most likely scenario remains that a magma intrusion will propagate from Svartsengi into the Sundhnúkur crater row. 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

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.

Flood warning system and jökulhlaups - Eyjafjallajökull

Jökulhlaups (glacier outburst floods) are more common in Iceland than elsewhere in the world because of the interaction of volcanoes with glaciers. The greatest jökulhlaups from the subglacial Katla volcano are among the largest floods that humans have witnessed.
