An erupting volcano grounded air traffic in Iceland this week. Southern Iceland’s Eyjafjallajokull volcano began erupting Sunday, sending ash and thirty-store-tall lava fountains into the air. The lava is flowing out of a half-mile-long rupture in an ice cap.
Iceland sits just south of the Arctic Circle in an area where two tectonic plates are constantly pulling apart. Volcanic eruptions occur there once about every five years.
