Iceland has lowered its warning code for possible volcanic disruption to the aviation industry at Bardarbunga volcano from red to orange – the second highest level.
The country’s Met Office has said there is now “no sign of an imminent eruption”.
However, the area was hit last night by an earthquake measuring 5.7, the biggest since tremors began 10 days ago.
There was one event during the night…it was a magnitude 5.7, the largest in this series," Palni Erlendsson, a geologist at the country's Met Office said.
"Activity is still deep and we see no signs of anything close to the surface."
Last week the country issued a red alert, which meant “eruption is imminent" with "significant emission of volcanic ash likely".
The UK Civil Aviation Authority (CAA) said there would be no impact on flights unless there was an actual eruption.
In 2010 much of Europe’s airspace was shut for six days, affecting more than 10 million people, after Iceland’s Eyjafjallajokull volcano erupted.
