Iceland lowers volcano alert, says small eruption no threat to aviation

REYKJAVIK/STOCKHOLM (Reuters) - Iceland reduced its aviation warning level to orange on Friday after concluding that a small eruption in the Bardarbunga volcano system that triggered a hours-long red alert actually posed no threat to aircraft.

No sign of ash like that from the Eyjafjallajokull eruption that shut much of Europe's air space in 2010 has been detected this time. But the Icelandic Metrological Office said a no-fly zone in a radius of 3 nautical miles just above the Bardarbunga volcano in central Iceland would remain in effect.
