National Geographic Iceland Volcano Eruption

Iceland's Eyjafjallajokull volcano erupted April 14, 2010, spewing aircraft-harming ash over most of Europe. It could cause Katla, its neighboring, larger volcano to erupt. NGC looks at Eyjafjallajokull before, during and after, explaining the science behind the chaos and the biggest disruption of air traffic since 9/11.
