Iceland has been experiencing increased earthquake activity this week, which has led officials to worry that a volcano named Bárðarbunga might erupt and disrupt travel to Europe.
On Monday, the Icelandic Met Office changed the aviation color code for the region to orange, which means the volcano "shows heightened or escalating unrest with increased potential of eruption." In 2010, after the Eyjafjallajökull volcano erupted, more than 100,000 flights to and from Europe were canceled due to the ash.
