Updated modeling shows Svartsengi’s magma volume reached 7.6 million m³ (268.3 million ft³) on February 26, 2024, and is now near or at the eruption threshold. With seismic activity increasing, particularly east of Sýlingarfell, the Norwegian Meteorological Agency has raised risk assessments, marking the Sundhnjúka crater series at high risk and adjusting other zones accordingly.
Data released by the Icelandic Met Office (IMO) shows that about 15 million cubic meters (530 million cubic feet) of lava flowed in the first seven hours of the eruption near Grindavik on February 8, 2024. The eruption has since decreased significantly but is still not over.
Updated findings as of February 1, 2024, show a heightened eruption risk near Grindavík, with about 6.5 million cubic meters (229 million cubic feet) of magma flowing into the Svartsengi chamber.
Recent volcanic activity in the Svartsengi area has led to continuous land uplift, although the exact rate is still being determined through GNSS measurements. Around 200 earthquakes, the largest measuring M1.4, have been recorded near the magma conduit since yesterday. Despite a reduction in earthquake frequency, significant risks, including ground collapse, remain for the nearby Grindavík area.
A day after a new volcanic eruption started near the evacuated city of Grindavik, Iceland, authorities are reporting a reduced flow of lava. While it’s unclear how long the eruption will last, they warn new cracks may be appearing on the surface within the city in the next few days.
Another eruption began south-southeast of Hagafell, Reykjanes Peninsula, Iceland at 07:57 UTC on January 14, 2024. The latest images show the lava flowing toward the town of Grindavik. The perimeter was about 450 m (1 470 feet) from the northernmost houses in the town around 08:40 UTC.
The Icelandic Meteorological Office (IMO) warns of an increased risk of eruption in the Reykjanes area, following their analysis on January 9, 2024, which reveals magma accumulation beneath Svartsengi similar to levels prior to the December 18 eruption.
The eruption site at Sundhnúksgígar, Reykjanes, Iceland, showed no active lava flow on December 21, 2023, with signs of diminishing activity and a decrease in seismic events.
A new volcanic fissure eruption started at 22:17 UTC on December 18, 2023, about 4 km (2.5 miles) NE of the town of Grindavik, Reykjanes, Iceland. The eruptive fissure is about 4 km long, with the northern end just east of Stóra-Skógfell and the southern end just east of Sundhnúk.
Although the rate of inflation at Svartsengi has decreased somewhat since Friday, December 8, 2023, it’s still greater than it was prior to the formation of the dike that traveled under Grindavík on November 10.
