Many Icelandic volcanoes are ice-covered, a factor that often contributes to explosive, ash-rich eruptions similar to Eyjafjallajökull in April 2010.
Paljud Islandil asuvad vulkaanid on jääga kaetud, mis sageli soodustab plahvatuslikke, tuharohkeid purskeid, nagu Eyjafjallajökulli purse 2010. aasta aprillis.
