A subglacial volcano is a volcanic form produced by eruptions beneath a glacier or beneath the surface of a lake within a glacier. Today they are most common in Iceland and Antarctica; older formations of this type are found also in parts of Canada. Their shape tends to be characteristic and unusual, with flat top and steep sides. If the heat produced by the volcano is high enough to melt through the ice layer, however, the volcano assumes a more conventional shape. ...more on Wikipedia about "Subglacial volcano"
