20252 Eyjafjallajökull           Discovered 1998 Mar. 1 by E. W. Elst at the European Southern Observatory.
The Eyjafjallajökull volcano in southern Iceland erupted in Mar. 2010 after an extended period of seismic restlessness. This eruption caused much inconvenience to aviation with its large amount of ash that extended all over Europe.
