Abstract: The eruption of Mount Ruapehu was, untilthe largest eruption this century in the central North Island. Previous accounts by Reed (), Oliver (), Cotton. Ruapehu is a very active andesitic composite volcano which has erupted five times in the past 10 years. Historical events have included phreatomagmatic eruptions through a hot crater lake and two dome-building episodes.
Ski-field facilities, road and rail bridges, alpine huts and portions of a major hydroelectrical power scheme have been damaged or destroyed by these eruptions. Destruction of Cited by: Mount Ruapehu (/ ˈ r uː ə ˌ p eɪ h uː /; Māori: [ˈɾʉaˌpɛhʉ]) is an active stratovolcano at the southern end of the Taupo Volcanic Zone in New is 23 kilometres (14 mi) northeast of Ohakune and 23 km (14 mi) southwest of the southern shore of Lake Taupo, within Tongariro National North Island's major ski resorts and only glaciers are on its nates: 39°17′S °34′E /.
Activity then subsided and in early November a new lake began to form in the crater. Ruapehu’s third major ash eruption of this episode began in the early morning of 17 June when a strong southerly wind carried the ash in a narrow plume northwards across Rotorua.

Eruption hazards depend on the volcano and eruption style, and may include explosions, ballistics (flying rocks), pyroclastic density currents (fast moving hot ash clouds), lava flows, lava domes, landslides, ash, volcanic gases, lightning, lahars (mudflows), tsunami, and/or earthquakes.
