Around 6 to 7 million m3 (212 to 247 million ft3) of magma have accumulated beneath Svartsengi, Iceland since the eruption on July 16, 2025. At the current rate of accumulation, the estimated threshold of 12 million m3 (424 million ft3) could be reached in the latter half of September, increasing the likelihood of a new eruption.
A new volcanic eruption has just begun north of the dam near Grindavík, Iceland, the Icelandic Met Office (IMO) reported at 09:45 UTC. A Coast Guard helicopter was sent to confirm the exact location and size of the eruption. This is the 11th eruption on the Reykjanes Peninsula since 2021 and the 9th on the Sundhnúk crater series.
A civil defense project to further raise earthen dams around the Svartsengi Power Plant was initiated on December 9, 2024. The effort aims to safeguard the infrastructure against future lava flows.
The eruption that started on November 20, 2024, at the Sundhnúks crater row near Grindavik, Reykjanes Penisula, Iceland is now the second largest in the volume of the eruptions that have occurred in the Sundhnúks crater row since December 2023.
Eruptive activity near Grindavik, Iceland, remains steady on November 28, 2024, with the eruption continuing from a single vent and lava flowing east and southeast. Gas pollution caused by northeast winds at 35 – 55 km/h (20 – 35 mph) was moving toward Grindavík today and was forecast to spread to nearby areas as the weather patterns change.
Lava from a nearby volcanic flow consumed the entire parking lot of Blue Lagoon geothermal spa resort in Grindavik, Iceland, at 14:00 local time on November 21, 2024.
A new volcanic fissure opened up between Stóra-Skógfell and Sýlingarfell, near the town of Grindavík, Iceland’s Reykjanes Peninsula, at 23:14 local time (LT) on Wednesday, November 20, 2024. This marked the year’s seventh eruption in this region.
The latest eruption in Iceland’s Reykjanes Peninsula has entered its 14th day with one crater active and relatively stable. Land uplift has resumed over the past weekend and considerable pollution is now being measured in many parts of the capital Reykjavik and the western part of South Iceland.
The Icelandic Met Office reported on June 8, 2024, that Grindavíkurvegur road was covered by lava for the third time since the Sundhnúkur eruption began on May 29. The lava, primarily flowing northwest, reached the road after breaching a protective barrier.
The ongoing eruption on Iceland’s Reykjanes Peninsula, starting March 16, 2024, continues to pose a threat as lava from the Sundhnúkur crater row thickens near Grindavík. Extrusion rates have remained consistent at 3 – 4 m3/s (106 – 141 ft3/s), with new data anticipated to further assess the situation.
