The amount of magma accumulated beneath Svartsengi continues to increase, with approximately 22 million cubic meters having accumulated since the last eruption in July 2025. This volume is approaching the higher end of what has been measured since the beginning of the ongoing events. A magma intrusion and eruption along the Sundhnúkur crater row is the most likely scenario, and the hazard assessment remains unchanged and valid until March 3rd. However, the Icelandic Meteorological Office continues to closely monitor developments and will update the hazard assessment if there are changes in activity. But here's where it gets controversial... Some experts argue that the magma accumulation rate is slower than previously thought, and the likelihood of an eruption may not be as high as initially predicted. And this is the part most people miss... The uncertainty regarding the timing of the next eruption is greater when magma accumulation is slow, and the current rate of accumulation spans several months. This could potentially delay the eruption, and the public should be aware of the possibility of a delayed response from authorities. Despite this, the Icelandic Meteorological Office maintains 24-hour monitoring of all natural hazards in Iceland, including real-time surveillance of seismic, deformation, and gas data, and warnings are issued when necessary. The public is encouraged to stay informed about activity updates on vedur.is and to be prepared for potential changes in the hazard assessment.
