Iceland volcanic eruption forces evacuation of Grindavík and Blue Lagoon as lava once again breaks through the earth’s surface on the Reykjanes Peninsula. The dramatic event began early Tuesday morning, when a swarm of earthquakes shook the region at 6:30 a.m. local time, followed by a fissure eruption near the fishing town of Grindavík. Authorities acted quickly, evacuating residents and tourists from high-risk zones, including Iceland’s famous Blue Lagoon thermal spa.
The eruption marks the 11th since 2021, continuing a period of renewed volcanic activity after centuries of dormancy. According to the Icelandic Meteorological Office (IMO), the eruption originated from the Sundhnúkur crater row, where magma had been building for several days. The fissure grew rapidly, extending nearly 700 meters within the first hour and crossing a protective barrier that had been constructed to defend the town after previous eruptions.
The town of Grindavík, located approximately 53 kilometers from Reykjavík, has faced repeated disruptions from the ongoing volcanic instability. Although largely evacuated in November 2023, some residents and businesses had slowly returned. However, with signs of ground deformation and intensified seismic activity, officials issued fresh evacuation orders. Most residents complied, though a few chose to stay behind despite warnings that this eruption could be stronger than previous ones.
Meanwhile, the Blue Lagoon—a luxury geothermal spa that draws visitors from around the world—was temporarily shut down as a precaution. The management confirmed that all guests and staff had been safely evacuated. The spa, which lies just a few kilometers from the eruption site, is closed until further notice.
Despite the dramatic visuals of glowing lava and volcanic smoke, Icelandic authorities emphasized that there is currently no threat to air travel. Keflavík International Airport remains operational, with no ash clouds affecting flight paths. The Icelandic Tourist Board assured the public that gas pollution is being closely monitored and restricted to isolated areas depending on wind direction.
“The area has been closed off and is completely closed until further notice,” said Snorri Valsson, spokesperson for the tourist board. He also noted that the eruption is still developing and updates will be shared as they become available.
The residents of Grindavík have grown accustomed to living with uncertainty. The town suffered major damage during a previous eruption that opened deep fissures in roads and rendered many buildings unsafe. The Icelandic state eventually purchased most of the properties, and many residents resettled elsewhere. This week’s eruption reinforces the instability of the area, with magma once again rising beneath the surface and cracking through defense walls meant to protect the town.
Experts say that the Sundhnúkur crater row has become increasingly active and poses a risk of larger eruptions as magma tunnels grow and shift. The IMO reported that current signals are stronger than those recorded in recent months, suggesting a significant volume of magma is in motion.
Tourism to Iceland had initially dipped after the 2023 eruptions, but visitor numbers quickly rebounded. In fact, foreign arrivals at Keflavík airport increased by 2% between 2023 and 2024. Hotel stays in November 2024 also surpassed those of the previous year, indicating the country’s resilience as a travel destination.
For now, the affected areas remain off-limits as scientists continue to monitor the fissure. While the rest of Iceland remains open for travel, this latest eruption serves as a reminder of the island’s ever-changing and powerful natural forces.
