Deformation measurements indicate ongoing land uplift and magma accumulation beneath Svartsengi. As noted last week, the volume of accumulating magma is now nearing the lower threshold believed to be required to trigger the next magma intrusion. Previous eruptions along the Sundhnúkur crater row have occurred between three days and four weeks after reaching this threshold. However, this does not guarantee that the next event will happen within a month—only that historical patterns suggest this as the most likely timeframe.

A series of low-pressure systems are expected to move across the country in the coming days, bringing strong southwesterly and southerly winds along with precipitation. These conditions may impact measurement capabilities, particularly affecting visibility and the sensitivity of seismic and real-time GPS monitoring. The Icelandic Meteorological Office will continue to closely track the situation, and the public is advised to stay updated on weather warnings and exercise caution when traveling.

The effusive eruption at the Halemaʻumaʻu summit crater reactivated.
In the evening of 2nd February, the activity preceded a small spattering at the north vent, culminating into vigorous fountaining until 09:52 PM local time tonight when it has become stable.
The activity accelerated from low-height (50ft/15m) to strong, high-height (250ft/80m) lava fountains accompanied with multiple lava flows in a short time (1 hour).
Seismic tremor peaked at 09:52 PM local time, and instruments recorded a ground uplift transition from inflation to deflation beneath Halemaʻumaʻu crater.
A livestream of the Kīlauea summit is available here.
This marks the 8th eruptive episode since December 23, 2024.
