A volcano in southwest Iceland erupted late Monday, spewing molten lava and billowing smoke across the region following weeks of heightened earthquake activity, according to the country’s Meteorological Office. The eruption, which began on the Reykjanes peninsula, poses a potential threat to the nearby town of Grindavik. Authorities had previously evacuated nearly 4,000 residents of Grindavik and closed the renowned Blue Lagoon geothermal spa, anticipating a significant eruption. The eruption, occurring only a few kilometers from Grindavik, prompted warnings as the ground cracked, and fissures extended toward the vulnerable town situated approximately 40 km southwest of Reykjavik, Iceland’s capital.
Reykjavik’s Keflavik International Airport remains operational, albeit with notable delays for both arrivals and departures. The eruption, characterized by vivid images and live streams showing molten rock shooting dramatically from fissures, signifies a surge in volcanic activity in the region. The Met Office reports seismic activity and GPS measurements indicating magma movement to the southwest, with the eruption potentially progressing toward Grindavik.
Measuring between 500 to 750 meters long, the fissures released an impressive 100 to 200 cubic meters of lava per second, significantly surpassing previous eruptions in the area. Local police raised alert levels, and civil defense authorities urged the public to avoid the vicinity while emergency personnel assessed the situation. The unpredictable nature of volcanic activity in Iceland, positioned between the Eurasian and North American tectonic plates, adds an element of urgency and caution to the ongoing situation.
The Reykjanes peninsula, renowned for its seismic and volcanic activity, has experienced several eruptions in recent years, often in uninhabited areas. In March 2021, the Fagradalsfjall volcanic system witnessed lava fountains erupting from a fissure, captivating thousands of Icelanders and tourists. The region sustained volcanic activity for six months. Subsequent eruptions occurred in August 2022 and July of the following year, captivating global attention. As authorities monitor the unfolding events, the eruption serves as a vivid reminder of Iceland’s dynamic geological landscape and the challenges posed by living in proximity to powerful natural forces.
