REYKJAVIK, Iceland (AP) - Iceland authorities say the aviation alert code has been changed to red, the highest level, because of a small fissure eruption near a volcano that lies under a large glacier.
No volcanic ash has been detected by the radar system and any ash produced has so far been minimal. All airports in Iceland are open but Icelandic Air Traffic Control has closed down the airspace from the ground up to 18,000 feet.
In 2010, Iceland's Eyjafjallajokul volcano erupted and sparked a week of international aviation chaos, with thousands of flights canceled. Aviation officials closed Europe's air space for five days, fearing that volcanic ash could harm aircraft engines.
