Specialist remark
An earthquake swarm that began on the 24th of august, about 20 km WSW of Eldey island has ended. The largest earthquakes measured were 4.1 in magnitude. About 200 earthquakes have been measured. There is always a chance that the activity will increase again.

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, that began on the 23rd of August in the Jökulsá á Sólheimasandi river, is 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
Situation on the Reykjanes Peninsula
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
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.
Read moreIncreased hazard due to changing conditions at the margin of Sólheimajökull glacier
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.

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

The weather app improved
Weather forecasts and the current weather condition can be checked through an improved weather app provided by IMO.
Forecasts are now provided for each hour and the meteograms are available again.
Location is detected if GPS on; alerts issued by the Met Office appear automatically during the day and a personal weather watch can be arranged.
An interactive weather map shows weather observations at any station in the country.
