A volcano had erupted in southwest Iceland, posing an immediate threat to a nearby fishing town that had been evacuated over fears of an outbreak, authorities said.
Early-morning live streams from the site showed fountains of molten rock spewing from fissures in the ground, the bright orange lava flow glowing against the dark sky.
The eruption began north of the town of Grindavik, which on Saturday was evacuated for a second time over fears that an outbreak was imminent amid a swarm of seismic activity, authorities said.
Iceland in recent weeks sought to build barriers of earth and rock to prevent lava from reaching Grindavik, but the latest eruption appeared to have penetrated the defences.
“According to the first images from the Coast Guard’s surveillance flight, a crack has opened on both sides of the defences that have begun to be built north of Grindavik,” the Icelandic Meteorological Office (IMO) said in a statement.
