Appropriately named Crater Lake, the historically active summit vent of New Zealand's Ruapehu volcano, is one of the world's most frequently active crater lakes. Nearly 50 explosive eruptions originating from a vent beneath the lake have been recorded during the 20th century. This view from the NW shows the 600-m-wide lake with glacier-clad Mitre Peak in the background.
