Specialist remark

A M4.7 earthquake took place in Bárðarbunga at 17:28 the 5th of October. An earthquake of this magnitude last took place on July 28 and they happen regularly in the Bárðarbunga caldera.

A magnitude 3.8 occurred just NW of Grimsey at 13:13 on October 4th. Similar earthquakes have been observed in the area in the past few days, but earthquakes there are quite common.

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

Elevated electrical conductivity has been observed in the Múlakvísl River over the past few days, and gas pollution has also been detected near Láguhvolar which points to a geothermal leak or a small glacier flood. Travelers are urged to exercise caution, stay away from the riverbanks and leave the area if they experience symptoms that could indicate exposure to gas.

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

Arctic cooperation

The Icelandic Meteorological Office cooperates with many agencies in related fields. With ongoing environmental changes, long term time-series are becoming increasingly important. These include time series of weather-related factors, such as temperature, rainfall, air pressure and solar and cloud cover, time-series on hydrology, glaciology, sea-ice condition, earthquakes, floods, ice and sediment load in rivers. Such data from IMO is important, providing a benchmark for assessing ongoing changes in the Arctic region.
