Activity of the volcanic eruption remains steady - 27.3.2024

Updated 27. March at 14:00 UTC

The volcanic eruption has been stable since Monday, 25 March. Eruption tremor has remained consistent since then, as has the activity in the three craters. Lava continues to flow southward from the craters mostly atop the lava field formed during the first days of the eruption. The following image shows the extension of the lava field as extrapolated from satellite images (ICEYE). The latest acquisition was on 26 March and it shows the widening of lava field towards the west, south of Hagafell, as well as further lava advancement towards the east and the south of the active vents.

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.

New understanding of ultra-rapid formation of magma filled cracks in the Earth - 8.2.2024

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.
