This morning (08. February 2024) at 06:02 UTC an eruption started close to Sundhnúkagígar, close to the area where the eruption started on 18. December 2023. The eruption fissure is at the writing of this around 3 km long, but the fissure is getting longer, based on views from web cameras.
This eruption is at favourable location. Since its far way at the moment from all buildings and infrastructure. That might change if the fissure stretches more to the south. This eruption started really quickly, according to Rúv, from the start of the earthquake swarm until the eruption started the time was only about 30 minutes. The time this took on 18. December 2023 was 60 minutes.
I’ll post more information later today when it is clear how this eruption is progressing.
