Prior to an eruption in 1971, the summit crater of Soufrière volcano was filled with a crater lake with a maximum depth of 180 m.  Its floor was 560 m below the north crater rim.  In 1971 a lava dome slowly and almost aseismically began growing on the crater floor.  It first breached the surface on November 3 and eventually formed a large island that left only a narrow moat of lake water. Photo by Jack Frost.
