Iceland evacuated its world-famous Blue Lagoon and the nearby town of Grindavík in Reykjanes Peninsula on Saturday, March 2, 2024, due to an intense seismic swarm indicating a new fissure eruption could start any moment.
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.
Volcanic eruption near Grindavik, Reykjanes Peninsula, Iceland resumed early Thursday, February 8, 2024.
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.
Icelanders build massive dykes to protect against lava flows from reactivated volcanoes near Reykjavik. The six volcanic systems, active for the first time in nearly 800 years, pose a significant threat to the Reykjanes peninsula, prompting around-the-clock construction efforts to safeguard homes and a crucial power plant.
Þorvaldur Þórðarson, a volcanology professor at the University of Iceland, suggests that recent earthquakes in the Reykjanes Peninsula could indicate magma accumulation under Húsfellsbruna, raising concerns about potential lava flows near Reykjavík.
In recent days, Svartsengi, Iceland, has experienced accelerated land rise, reaching up to 8 mm (0.3 inches) daily, attributed to magma accumulation under the area. While seismic activity remains mild, the risk assessment for Grindavík has been downgraded to orange, with a continued high risk for crack collapse.
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.
