The eruption occurred at 6 a.m., according to the country’s meteorological office, on a mountain ridge on the Reykjanes peninsula, where a significant part of Iceland’s population, about 375,000 people, lives, although it does not does not seem to be in danger.
Iceland’s civil defense agency said the Blue Lagoon, a geothermal spa resort popular with tourists, was evacuated Thursday morning.
Grindavik, a small fishing town of 3,800 that is the closest population center to the volcano, was evacuated before the volcano erupted in January and destroyed part of the town. It remains empty.
Video taken from a Coast Guard helicopter showed a fissure estimated to be nearly two miles wide, with tall fountains of lava.
Volcanic breakouts are not uncommon in Iceland, but the volcanoes on the Reykjanes Peninsula were dormant for about 800 years until 2021, and there have been several eruptions since.
