Iceland's Volcanic Eruption And Its Aftermath A volcanic eruption in Iceland on April 14 sent a plume of volcanic ash more than 30,000 feet into the air. The ash, which has drifted south and east, has snarled air traffic across Europe, with massive flight delays that have had reverberations around the world.

Iceland's Volcanic Eruption And Its Aftermath

The ash from a volcanic eruption in Iceland April 14 has resulted in massive flight delays.

This infrared image shows ash spewing out of Iceland's Eyjafjallajokull volcano. It was taken April 17 by a NASA spacecraft. Hotter areas, shown in red, can be seen at the ash plume's base. NASA/JPL/EO-1 Mission/GSFC/Ashley Davies hide caption
