Specialist remark
Magma accumulation at Svartsengi continues at a steady rate, similar as before the last three eruptions. If magma accumulation continues at this rate, the magma volume will reach the threshold of estimated volume needed to trigger a dyke propagation and even an eruption next week. Before last eruptions the total volume of magma accumulated at Svartsengi has been between 8 to 13 million m3.

February 25. at 07:57 a earthquake of M3.2 was measured in Bárðarbunga Volcano.

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

Magma volume beneath Svartsengi reaching similar level as prior to last eruptions
Updated 23. February at 15:00 UTC
Model calculations indicate that approximately 5 million cubic meters of magma have now accumulated beneath Svartsengi. Considering the precedent set by the previous volcanic eruptions in the Sundhnúkur crater row, the likelihood of an eruption is very high once the volume reaches 8-13 million cubic meters. Based on the results of the model calculations, this could occur early next week if magma accumulation continues at the current rate.
It should be noted that there is a degree of uncertainty in this interpretation, and it cannot be asserted that the behavior will be identical to the last eruption. Additionally, there is a possibility that magma could migrate from Svartsengi to the Sundhnúkur crater row without resulting in a volcanic eruption.

New understanding of ultra-rapid formation of magma filled cracks in the Earth
On 10 November 2023 the town of Grindavík in Iceland was evacuated as massive amounts of magma suddenly flowed into a magma filled crack that propagated underneath the town. Magma was emplaced in a 'vertical sheet' type intrusion in the Earth's crust. An international team of scientists explains the formation of the intrusion, and conditions for ultra-rapid flow into cracks, in a new publication in the prestigious scientific journal Science.

Conclusion of Grímsvötn Glacial Outburst Flood
Updated 23 January at 9:00 UTC
Since the glacial flood reached its peak in the river Gígjukvísl approximately a week ago, the water level has been decreasing and is now comparable to what it was before the flood. The seismic tremor measured on the seismometer at Grímsfjall has also declined, with seismic noise now back to normal levels. Since last week Monday, 21 earthquakes have been recorded in Grímsvötn, including two earthquakes exceeding magnitude two.

The uplift in Askja has slowed down
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
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
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.
