Iceland has raised the aviation code for the Bardarbunga volcano to red, indicating some eruption.
It was reported Tueday Aug. 19, 2014 that thousands of small intense earthquakes are rocking Iceland amid concerns that one of the country’s volcanoes may be close to erupting.
Iceland has raised its aviation alert level for the risk of a possible volcanic eruption to orange, the second-most severe level.
The alert is worrisome because of the chaos that followed the April 2010 eruption of Eyjafjallajokul, when more than 100,000 flights were cancelled because of volcanic ash floating in the atmosphere. The ash is an aviation safety hazard.
