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

The Icelandic Met Office has received reports of sulfur smell near the Markarfljót, Emstruá, Múlakvísl and Jökulsá á Sólheimasandi glacier rivers. In addition over the past few days, an increased level of volcanic gases (CO2 and H2S) have been measured at Láguhvolar. This is a sign of geothermal leak into the rivers due to warm weather lately and a small annual glacial flood in Emstruá. It is important for people to exercise caution due to gas pollution, especially near the riverbanks and the river's source.

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

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.

Situation on the Reykjanes Peninsula - 3.7.2026

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.

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.

IMO expert to lead international collaboration on geohazards - 12.5.2026

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.
