Volcanic activity north of Grindavík continues to decrease, with little visible activity on webcams or in recent drone footage. However, seismic activity continues. Earthquake activity near the southern part of the magma dike, close to Grindavík, has decreased, while activity at the northern end of the dike continues with similar intensity and has shifted even further north in recent hours. The seismic activity now extends almost 9 km farther north than the northernmost eruption fissure formed during the August 2024 eruption. The largest earthquakes have been around magnitude 3 and have been felt in Vogar, which is about 7 km northwest of the active area.

GPS deformation data shows that magma continues to accumulate beneath Svartsengi, although the pace of land uplift has slightly decreased in recent weeks. Despite the slower uplift, experts still consider it likely that a magma intrusion and/or eruption will occur along the Sundhnúkur crater row.
Read moreAt around 14:30 yesterday (12 March 2025), a rather intense earthquake swarm began offshore Reykjanestá. The swarm was most intense at the beginning when about 50 – 60 earthquakes were recorded in the first few hours. As the day progressed, the activity decreased but then increased again shortly before midnight when an earthquake of magnitude 3.5 occurred. When the activity increased again in the evening, it shifted slightly westward as the image shows (blue circles indicate the location of earthquakes that occurred at the beginning of the swarm yesterday, while yellow and red ones show earthquakes from late last evening and night).
