Lava poured down a volcano near Iceland's capital, Reykjavik, on Friday 4 June after thousands of small earthquakes in recent weeks.
The eruption occurred near Fagradalsfjall, a mountain on the Reykjanes Peninsula, around 30km southwest of the capital.
Some four hours after the initial eruption on Friday night - the first on the peninsula since the 12th century - lava covered about one square kilometre.
Eyewitness footage from YouTuber John Bear captured huge volumes of lava cascading down the mountain.
He said Friday was the last day the eruption site could be accessed for filming and the area is now blocked off by streams of cooled, black lava.
