Watch live as a volcano in southwest Iceland erupts on Tuesday, 19 December, finally erupts after weeks of intense earthquake activity.
“Warning: Eruption has started north of Grindavíkby Hagafell,” the country’s Met Office said on its website.
The eruption began a few kilometres from the fishing town, whose nearly 4,000 inhabitants were evacuated last month.
Authorities also closed the nearby Blue Lagoon geothermal spa.
Reykjavik’s nearby Keflavik International Airport remained open, albeit with numerous delays at both arrivals and departures.

The Icelandic Met Office said the crack in the earth’s surface was around 3.5 km long and had grown rapidly.
“Seismic activity together with measurements from GPS devices indicate that the magma is moving to the southwest and the eruption may continue in the direction of Grindavik,” it added.
