This is the slowly-advancing red-hot lava from Iceland’s Bardarbunga volcano – which erupted last month.
The footage shows scientists from the University of Iceland’s Institute of Earth Sciences using the lava to boil some water.
There are fears ash from the volcano could cause similar problems to that of Eyjafjallajokull in 2010, which resulted in the largest air-traffic shutdown since World War II.
Lava fountains of more than 50m prompted authorities in Iceland to raise its ash warning for aviation to red, the highest level.
It was later downgraded to orange, the second highest level, where it remained on September 24, according to latest updates.
