Three days of earthquake activity at Iceland's Bardarbunga volcano prompted the country's meteorological office to issue an orange alert Monday for a heightened risk of eruption.
The volcano sits underneath Europe's largest glacier, raising concerns that an eruption would loft large amounts of steam and ash into the air as magma meets meltwater, disrupting air travel.
Recent eruptions in Iceland have had a long reach.
In May 2011, the most active volcano on the island, Grimsvötn, erupted, forcing airlines to cancel some 900 flights to and from Iceland, Britain, Greenland, Germany, Ireland, and Norway over a three-day period. The volcano sent plumes of ash up to seven miles high, overspreading air routes. Bardarbunga shares the same glacial skull cap sitting atop Grimsvötn.
