Specialist remark

Volcanic unrest near Grindavík
Recent days, the seismic activity has been rather similar but between 300 and 400 earthquakes have detected each day. Yesterday around 370 earthquakes were measured, the largest one M2.7 near Hagafell. Since midnight today around 320 earthquakes have been detected, all below M2.0, and most of them located near the central part of the dike intrusion.

Information regarding the number and size of earthquakes in the vicinity of Grindavík will be updated here four times a day, around 06:00, 11:00, 18:00, and 23:00 UTC. Further details and interpretation of the events near Grindavík can be found in the front page news, which is updated regularly.

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

Avalanches

Avalanche conditions

Widely, some new snow has accumulated on top of old stable melt-freeze snow. Those two may be poorly bonded. A thin but wide human triggered avalanche released in Ljósavatnsskarð December 1st.

Seismic activity still decreasing - 1.12.2023

Updated 1. December at 16:50 UTC

The seismicity on the peninsula continues to decrease. For the past few days, the automatic earthquake location system has been detecting relatively few earthquakes, mostly micro-earthquakes below magnitude one. The most recent seismicity is concentrated in the area between Sýlingarfell and Hagafell, where most likely the dike is fed by magma accumulating beneath Svartsengi. Some deformation is still detected at the cGPS stations located close to the dike, but the signal is now mainly interpreted as the response of the crust to the inflation ongoing in the Svartsengi area.

The uplift in Askja has slowed down - 3.10.2023

There is evidence of recent changes in the deformation data (cGNSS) around Askja. The deformation rate has decreased since the beginning of August and the signal has flattened at several stations within or around the caldera. At this stage it is uncertain what process is causing this pressure reduction, possibly the source of the inflation has been shut off or it could be related to an outflow of magmatic fluids.

Flood in Skaftá - 29.8.2023

Updated on 29 August, at 17:00

Hydrological measurements in Skaftá at Sveinstindur show that the increase in discharge has slowed down.The discharge is estimated 620 m³/s at 15:00 compared to 600 m³/s at 9:00 this morning.

No visible changes in geothermal activity around Askja and Víti - 23.8.2023

The field trip conducted by a team from IMO last week has been completed succesfully.

Preliminary results indicate no changes in the gases or waters compared to previous years while further sample and data analyses are ongoing. Visual inspections and temperature and pH measurements do not point to any clear changes in geothermal activity around Askja including in Víti. The observation on 12 August at the edge of Bátnshraun which was reported as a possible steam plume is now recognized as dust caused by a minor rock fall on a steep slope of the caldera wall.

The situation at Askja remains unchanged - 16.8.2023

The latest deformation data indicates that the inflation continues at Askja with the position and depth of the inferred magma source unchanged since September 2021. The magma is accumulating at a depth of about 3 km, and there are currently no indications from geodetic observations that the magma has shallowed further. Ten days have passed since last activity was seen in the crater close to Litli-Hrútur and since volcanic tremor reached its background level. No deformation is detected in the area and the seismic activity has decreased significantly.

The activity in the Reykjanes Peninsula has entered a new phase - 10.8.2023

Updated 10 August 2023

The Icelandic Met Office has updated the hazard map for the eruption site. The vicinity of the eruption area is still dangerous. High temperatures characterize the lava field. The solidified crust can be very thin in places with very hot and molten lava underneath. The edges of the new lava field are unstable and large chunks of lava can fall sudden. As a result of past activity there are fractures in the area that pose danger. The new lava continues degassing and hazardous gases can collect in depressions
