A volcano has erupted on the Reykjanes peninsula of south-west Iceland after weeks of intense earthquake activity.
About 4,000 people were evacuated last month from Grindavik, a fishing town about 4km (2.5 miles) away.
The eruption started north of the town at 22:17 local time (22:17 GMT) on Monday, the Icelandic Met Office said.
A resident living near Grindavik described “crazy” and “scary” scenes that night, and said she could still see the volcano exploding on Tuesday.
Iceland has been braced for volcanic activity for weeks. Since late October, the region around the capital Reykjavik has been experiencing an increase in earthquake activity.
The eruption can be seen from Reykjavik, which is about 42km north-east of Grindavik.
An eyewitness in the capital told the BBC that half of the sky in the direction of the town was “lit up in red” from the eruption, and smoke could be seen billowing into the air.
Experts say they don’t expect the eruption to bring the same level of disruption as one that took place elsewhere in Iceland in 2010, which halted European air travel.
The Icelandic Met Office said at 12:30 GMT on Tuesday that the power of the eruption was decreasing, but that gases from the volcano could still be felt in Reykjavik on Tuesday evening or Wednesday morning.
Aoalheiour Halldorsdottir, who lives in Sandgeroi – about 20km from Grindavik – said she had seen the eruption from her home.
“It was crazy to see it with my own eyes. We have had volcano explosions before, but this was the first time I got really scared,” she told BBC News.
“We’re used to volcanoes [erupting], but this was crazy.”
She said there was some “panic” on Monday night, and that she had bought extra supplies of water, but that things had largely returned to normal on Tuesday.
“I’m at work now, and I can still see it. I can see the lights in the sky,” she said.
Hans Vera was evacuated from Grindavik last month, but hoped before Monday’s eruption to return home for Christmas.
But he said: “I don’t see that in the future they will let people get close to Grindavik – so we are back in the waiting game.”
Iceland’s foreign minister, Bjarni Benediktsson said on X, formerly Twitter, that “there are no disruptions to flights to and from Iceland, and international flight corridors remain open”.
“The jets [of lava] are quite high, so it appears to be a powerful eruption at the beginning,” he said.
Hallgrimur Indrioason, a reporter for the state-owned Icelandic National Broadcasting Service (RUV), said the eruption could be seen dozens of kilometres away in Reykjavik, and described the view as “quite spectacular”.

Images and videos posted on social media showed lava bursting from the volcano just an hour after an earthquake swarm – a series of seismic events – was detected.
