Crater Lake, at the summit of Ruapehu volcano, has produced frequent phreatic explosions during historical time. The depth of the 600-m-wide crater has varied dramatically in recent years, with the maximum depth ranging from 0 to 300 m. Occasionally the lake has been completely drained by explosive eruptions, as occurred most recently in 1996. The 2797-m summit of Ruapehu, Tahurangi Peak, is at the center behind the lake in this view from the north.
