Grindavík, Iceland – A significant volcanic eruption has erupted near the town of Grindavík on the Reykjanes Peninsula, prompting swift evacuations and raising concerns about the safety of local residents and infrastructure. The eruption, which started near Sundhnúkagígar, was confirmed by the Icelandic Meteorological Office (IMO) on Wednesday, following weeks of heightened seismic activity in the region.
Eruption details and immediate impact
The IMO reported that the eruption plumes have reached heights of at least 50 meters. The eruption began just weeks after the conclusion of a previous volcanic episode that started on March 16. The nearby Blue Lagoon geothermal spa, a major tourist attraction, was promptly evacuated as a precautionary measure.

Emergency services were quick to respond, with evacuation protocols activated for the town of Grindavík and surrounding areas. This eruption is the fifth since December on the Reykjanes Peninsula, underscoring a period of intense geological activity.
Evacuations and infrastructure concerns
The town of Grindavík, home to about 4,000 residents, had already seen significant evacuations last November before the series of eruptions from December to March. During the January eruption, lava flows reached the streets of Grindavík, engulfing three homes. Since then, only a few residents had returned, mainly to areas considered less vulnerable to lava flows.
The Svartsengi power plant, which supplies electricity and water to approximately 30,000 people on the peninsula, was also evacuated. The plant had been operating remotely since the first eruption in December, and barriers were constructed to protect it from lava flows. The accumulation of 20 million cubic meters of molten rock in the magma chamber beneath Svartsengi highlighted the ongoing risk.
Seismic activity and geological context
In the lead-up to the eruption, the IMO recorded “intense earthquake activity,” with around 400 earthquakes detected in the week prior to the eruption near the Sundhnúkagígar crater row. This significant seismic activity was a precursor to the volcanic event, indicative of the underlying tectonic movements.
Historically, the Reykjanes Peninsula had not experienced volcanic eruptions for 800 years until March 2021. Volcanologists believe that this marks the beginning of a new era of seismic and volcanic activity in the region, with the recent eruptions providing evidence of this shift.
Broader implications and ongoing monitoring
The latest eruption has had a notable impact on local infrastructure and tourism. Road closures, flight disruptions, and the evacuation of major tourist sites like the Blue Lagoon have all been necessary responses to the volcanic activity. Authorities are continuously monitoring the situation, using satellite imagery and ground-based observations to track the progression of the eruption and assess further risks.
“We are closely monitoring the situation and have mobilized all necessary resources to assist those affected,” stated Iceland’s Minister of Civil Protection. “Safety is our top priority.”
Looking forward
As the volcanic activity continues, residents and visitors are urged to stay informed through official channels and adhere to safety advisories. The resilience and preparedness of the Icelandic people remain crucial as they navigate the challenges posed by this natural event. With ongoing vigilance and community cooperation, Iceland aims to mitigate the impact of the eruption while safeguarding lives and infrastructure.
