The summit plateau of the mountain contains Crater Lake. In 1995, Mount Ruapehu had a series of major eruptions where the magma emptied out the lake. Mount Ruapehu’s hydrothermal vent system was discovered through analyzing the mass and energy budget of Crater Lake and from geochemical analyses. Recent analyses have suggested an open vent system, which allows heat to transfer to Crater Lake through a pipe. The upper region of the vent is said to have a “hydrothermal system with a single-phase liquid and vapor regions separated by a two-phase liquid-vapor region” (Ingham et al. 2008). However, this hypothesis is yet to be verified. Ingham submitted a report of a 3-D inversion of a regional magnetotelluric (MT) survey of Mount Ruapehu.
