Authorities have evacuated families, hotel guests, and tourists from Grindavík, the nearby Blue Lagoon resort, and other surrounding areas as a precaution.
The eruption in the Sundhnúkur volcano on the Reykjanes Peninsula, which began early Wednesday, is the 12th since volcanic activity reawakened in the region in 2021.
According to Iceland’s meteorological office, magma forced through the crust opened a fissure between 700 and 1,000m long.
“(It does) not threaten any infrastructure at this time,” the office said, adding that GPS and deformation data suggest it was a relatively small eruption.
Grindavík, which once housed nearly 4,000 people, was evacuated last year and remains largely empty due to ongoing volcanic risk.
