From Science Fair:
The last time Iceland's Eyjafjallajokull volcano blew, the eruption lasted more than a year, from December 1821 until January 1823, reports Sally Sennert, a geologist at the Smithsonian Institution.
"This seems similar to what's happening now," she says.
The volcano is erupting small, jagged pieces of rocks, minerals and volcanic glass the size of sand and silt into the atmosphere, according to the U.S. Geological Survey. This volcanic ash can even be as small as 1/25,000th of an inch across.
Volcanic ash is formed during explosive volcanic eruptions. Once in the air, the wind can blow these tiny ash particles tens to thousands of miles away from the volcano. Life-threatening and costly damages can occur to aircraft that fly through an eruption cloud, reports the geological survey.
