There are 18 glaciers on Mt Ruapehu, but only six sprawl over a hectare or more. After the 1996 eruption it was recognised that a catastrophic lahar could again occur when Crater Lake burst the volcanic ash dam blocking the lake outlet as it did in 1953. [6] Eruptions during this period are believed to have built a steep volcanic cone around a central crater, which would have been located somewhere near the present-day upper Pinnacle Ridge. Ruapehu Summit Plateau from Dome Ridge. The volcano is forested below its line of permanent snow cover. Mt Ruapehu has 9 glaciers, up to 130 m thick, 1.8 km long and covering 4 square kilometres (0.5% of the Park area). The ERLAWS system detected the 2007 lahar, and roads were closed and railway traffic stopped until the lahar had subsided. Mount Ruapehu is situated on the Taupo Plateau, which rises 2,000 to 3,000 feet (about 600 to 900 m) above sea level, Ruapehu erupted in 1945–46 and again in 1995–96.
