Iceland: Volcanic eruption ongoing in the Reykjanes Peninsula as of March 19 /update 1

The volcanic eruption that began in the Reykjanes Peninsula late March 16 is ongoing as of March 19. The eruption occurred at around 20:23 March 16 between Hagafell and Stora Skogfell in the Sundhnukur crater row following an increase in seismic activity. As of March 19, the Icelandic Meteorological Office (IMO) has advised that eruptive activity is ongoing but relatively stable. The propagation of lava has slowed significantly since the initial eruption after spreading mainly southward and westward from the 3 km (1.9 mile) fissure during the first few hours of the eruption.

Authorities declared a state of emergency due to the volcanic eruption March 17. The Blue Lagoon Hotel and Spa closed late March 16 and evacuation orders have been issued for residents in Grindavik. All roads to and from Grindavik and several other areas near the area of recent volcanic activity remain closed. Defensive barriers have been built around key infrastructure since eruptive activity began occurring in the area in December 2023 and are expected to prevent some roads and pipelines, as well as much of Grindavik, from being heavily impacted by the lava flows.

Due to the ongoing eruption, officials may expand evacuation orders and road closures at short notice. Eruptive activity at the volcano could prompt transport disruptions in the surrounding area. Lava flows could block highways and damage structures. Ashfall may reduce visibility, causing hazardous driving conditions, and could also pose an increased threat to air traffic; flight disruptions are possible at Keflavík International Airport (KEF) if sustained eruptive activity continues and winds direct volcanic material in the general direction of the airport.
