Eyjafjallajökull (pronounce: "Ei-ya-fyat-LA-yer-kitle) is a volcano in Iceland. The name means "island-mountains glacier".
The south end of the mountain was once part of the coastline of the Atlantic ocean. The sea gradually moved about 5km south. Now there are beautiful steep cliffs and waterfalls.
The volcano erupted several times in 1821 and 1822. Some cattle and sheep died, presumably because of fluoride poisoning.
