Details for: Ruapehu
Massive Ruapehu volcano, seen here from the south, forms an elongated massif composed of at least 4 overlapping volcanic edifices. Ruapehu anchors the southern end of the Taupo volcanic zone, and contains an active summit crater lake that makes Ruapehu one of New Zealand's most active volcanoes. Phreatic explosions have often produced mudflows, which have affected a ski area on the upper flanks and river valleys below the volcano. Photo by Bruce Houghton, 1980 (Wairakei Research Center).
