Uplift continues beneath Svartsengi but the rate has decreased - 22.4.2025

Update 22. April kl. 12:30 UTC

Uplift in Svartsengi continues, but the rate has significantly decreased and is now similar to the period before the eruption that began on April 1. As magma accumulation continues beneath Svartsengi, repeated magma intrusions and even eruptions in the Sundhnúkur crater row must be considered.

Uplift continues beneath Svartsengi - 8.4.2025

Updated April 8, at 16:15 UTC

Deformation measurements clearly show that uplift beneath Svartsengi is ongoing. The current uplift rate is faster than that observed following previous eruptions. This may be explained by the large volume of magma — around 30 million cubic meters — that was released from the system during the most recent event.

However, it is still too early to predict how the rate of magma accumulation will develop. Past events have shown that accumulation rates typically decline as more time passes between eruptions. At least a week, and possibly several weeks, will need to pass before we can evaluate if — and how — the rate of accumulation will change.

Eruption at the Sundhnúkur crater row remains likely - 25.3.2025

Updated 25. March at 15:00 UTC

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.

Earthquake swarm ongoing offshore Reykjanestá - 13.3.2025

At 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).
