Magma intrusion remains likeliest eruption scenario at Sundhnúkagígaröð

Continued land uplift at Svartsengi points to ongoing magma accumulation, with an intrusion toward the Sundhnúkagígaröð volcanic crater row remaining the most likely scenario, mbl.is reports.

The Icelandic Meteorological Office says recent deformation measurements show the ground at Svartsengi has risen steadily in recent months. The data suggest magma is still accumulating several kilometres beneath the area and pressure is increasing.

Seismic activity has been very low recently and is considered normal background activity, according to the office. A magma intrusion could lead to an eruption, but it is not possible to predict when the next event will occur. The warning period could be short.

Authorities will continue to monitor the situation. The current hazard map is valid until 5 January 2027, unless changes in activity or new data prompt an earlier review.
