REYKJANES 12.11.2025

The Icelandic Meteorological Office (IMO) reported that an eruption began on 16 July in an area NE of Stóra Skógfell, along the Sundhnúkur crater row, within the Reykjanes volcanic system. IMO issued a Volcano Observatory Notices for Aviation (VONA) at 0106, raising the Aviation Color Code to Red (the highest level on a four-color scale), after monitoring data indicated a dike intrusion. An intense seismic swarm that began at 0120 was located between Stóra-Skógfell and Sýlingarfell, and deformation data indicated that the dike was propagating towards the S and rising to the surface. A fissure eruption began at 0356. The eruption was observed in webcams along with both drone and helicopter overflights. Lava fountains rose along the fissure, but no ash was present in the air; the Aviation Color Code was lowered to Orange at 0435. By 0505 the fissure was 700-1,000 m long and opening towards the N. Lava fountains continued to rise along the fissure and lava flows traveled mostly SE. Seismicity had decreased by 0845. Lava flows advanced W and to a greater extent to the E. Pele’s hair drifted downwind. High levels of volcanic gases were measured in Reykjanesbær prompting authorities to advise residents to stay indoors. By noon two fissures were erupting; the larger fissure at the Sundhnúkur crater row was about 2.4 km long, and a smaller fissure, about 500 m long, had opened W of Fagradalsfjall.
