No activity has been observed at the eruptive fissure since yesterday afternoon, though glowing is still visible in the newly formed lava. The area remains unstable and hazardous. Measurements show that the lava volume erupted yesterday was about 0.4 million cubic meters. This estimate is based on data collected by experts from the Icelandic Institute of Natural History during an aerial survey of the eruption site yesterday afternoon. The lava field formed is the smallest one observed since the eruption sequence at Sundhnúkur crater row began in December 2023. Its volume is approximately 1/6 of the lava field from the January 2024 eruption, which was the second smallest event in the sequence.

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).
