Iceland has raised its aviation warning level after a fresh eruption from a fissure near the Bardarbunga volcano.
However, Iceland’s Met Office described the eruption as “a very calm lava eruption” which could “hardly be seen on seismometers”.
The warning means planes will be banned from flying within 6,000 feet of the volcano peak.
Iceland’s Eyjafjallajokull volcano erupted in 2010, producing ash that disrupted air travel across Europe.
Sunday’s eruption in the Holuhraun lava field area was “calm but continuous”, authorities said.
It happened in roughly the same place as an earlier eruption on Friday morning, and is the third to happen in the area in the last week.
The latest eruption is more intense than Friday’s with around 10 times more lava said Armann Hoskuldssonk, a geologist from the University of Iceland.
BBC transport correspondent Richard Westcott says that even if a big cloud of volcanic ash were emitted, it would not cause the same level of disruption to flights that brought Europe to a halt in 2010.
He says new equipment that airliners and engine makers have been testing would allow planes to identity and fly around ash clouds.
All airports in Iceland are still functioning normally
