The Bardarbunga volcano could be counting down toward an eruption with possible impacts on millions of people.
The eruption threat level for Bardarbunga was raised to orange on Monday, the second-highest level. This occurred following several earthquakes in the past week, including the strongest quake measured in the region since 1996, according to the Iceland Meteorological Office.
Although no eruption has occurred thus far, the recent earthquakes have raised concern that a major eruption is possible in the near future.
In 2010, the Eyjafjallajokull eruption in Iceland spewed ash into European Airspace leading to thousands of flight cancelations which impacted millions.
Airlines lost almost $2 billion due to the cancelled flights, according to Bloomberg News.
Upper-level winds will generally be north to northwest across the region over the week ahead which would transport any ash toward Ireland and the United Kingdom if an eruption was to occur.
