Volcanic haze and elevated levels of sulfur dioxide (SO2) from the Sundhnúk crater range eruption are affecting the western half of Iceland, especially the southwesternmost regions. The Icelandic Meteorological Office forecasts persistent volcanic haze in the south and west through Monday, due to slow and variable winds.
While the eruption at the Sundhnúksgígar crater row, southeast of Litla-Skógfell, Iceland continues on July 18, 2025, the eruptive activity has declined in the last 24 hours.
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.
An earthquake swarm began off Reykjanestá, Iceland at 14:30 UTC on March 12, 2025, with more than 104 events by 18:20 UTC.
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.
The levels of sulfur dioxide (SO2) are rising in the vicinity of Grindavik due to the ongoing volcanic eruption on the Reykjanes Peninsula, Iceland. The gas pollution has reached unhealthy levels, as reported by the Icelandic Meteorological Office (IMO).
Authorities in Iceland have deployed at least 12 water cannons on the L3 defense wall to cool a 360 m (X feet) large section of lava and protect critical infrastructure, including the Svartsengi geothermal facility and the Njarðvíkuraeð hot water pipeline, which is important for the Suðurnesj region. Initial testing on one pump was successful, and the operation will begin with six eastern cannons, followed by the remaining units. The cooling process is expected to take several days.
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.
