The eruption of Eyjafjoell-volcano on Iceland started 21st March 2010. The first part took place on a new fissure which opened on a saddle between the glaciers Myrdalsjoekull and Eyjafjallajoekull. The second part began some days after the first eruption ended. This was a powerful sub glacial eruption in the caldera at the summit of Eyjafjallajoekull.
