Specialist remark

The eruption that started at 23:14 last night, November 20 on the Sundhnúksgígar Crater Row, continues. Activity has slightly decreased, the fissure is still most active around its middle. Lava flow continues to the west and north. The western lava tongue, the one that flows between Sýlingarfell and Stóra Skógfell, flowed over Grindavíkurveg at about 04:30 and went over Njarðvíkuræð at 7:55. The western lava tongue has now reached the Blue Lagoon parking lot. The northern lava tongue does not flow towards any infrastructure.

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

Eruption activity remains fairly steady since this morning - 21.11.2024

Updated 21. November at 16:45 UTC

Eruptive activity between Stóra-Skógfell and Sýlingarfell appears to be similar to that observed earlier this morning. Seismic activity and deformation at the eruption site remain very low.

Initial measurements suggest that the volume of magma that has travelled from Svartsengi towards the Sundhnúkur crater row is equivalent to half the volume that moved during the eruption on August 22. More detailed results are expected in the coming days.

Ground Uplift and Magma Accumulation Continue Beneath Svartsengi - 19.11.2024

Updated 19. November at 14:45 UTC

Seismic activity in the Sundhnúkar crater row remains relatively low. A few earthquakes have been recorded daily, most of them located between Stóra-Skógfell and Sýlingarfell. On some days in the past week, bad weather has affected the sensitivity of the seismic monitoring system, potentially obstructing the detection of the smallest earthquakes.

Continued greenhouse gas emissions could trigger a regional cooling around the North Atlantic - 19.10.2024

Continued greenhouse gas emissions increase global warming, but could trigger a regional cooling around the North Atlantic. In an open letter released today at the Arctic Circle conference in Reykjavík, Iceland, 44 leading experts on ocean circulation and tipping points from 15 countries appeal to the Nordic Council of Ministers to take this risk seriously, initiate a risk assessment and take steps to minimize this risk as much as possible.

New Icelandic Met Office weather and climate supercomputer, becomes operational - 23.9.2024

The National Meteorological Institutes of Iceland, Denmark, Ireland and the Netherlands have joined forces to respond to climate change with more timely weather forecasting on a new, now operational, common supercomputer. This helps prepare each nation for the impacts of weather patterns, which are expected to become more extreme and more challenging to forecast.

One month since the start of the eruption at the Sundhnúkur crater row - 16.4.2024

Today marks one month since the beginning of the eruption that is ongoing at the Sundhnúkur crater row. The eruption, which began on the evening of March 16, is the fourth in a series of eruptions that started when magma began accumulating beneath Svartsengi in late October 2023.

Seismic swarm in the northwest past of the caldera in Askja yesterday - 26.3.2024

Yesterday (25 March) a seismic swarm occurred in the NW part of the Askja caldera. About 30 earthquakes were detected between 08.00UTC and midday. The largest earthquake detected had a magnitude M3,5 at a depth of about 5 km. Three earthquakes with magnitudes between M2 and M2,5 were also detected, the rest of the activity was characterized by smaller events. Overall, the seismic activity in the Askja has been quite stable between months and unchanged until yesterday. Looking back, we can see that earthquakes with magnitude above M3 were detected in January 2022 and October 2021.
