Mount Ruapehu is an active stratovolcano at the southern end of the Taupō Volcanic Zone and North Island volcanic plateau in New Zealand. It is 23 km (14 mi) northeast of Ohakune and 23 km (14 mi) southwest of the southern shore of Lake Taupō, within the Tongariro National Park. The North Island's major ski resorts and only glaciers are on its slopes.
The Taupō Volcanic Zone (TVZ) is a volcanic area in the North Island of New Zealand. It has been active for at least the past two million years and is still highly active.
Manawatū-Whanganui is a region in the lower half of the North Island of New Zealand, whose main population centres are the cities of Palmerston North and Whanganui. It is administered by the Manawatū-Whanganui Regional Council, which operates under the name Horizons Regional Council.
Waiouru is a small town in the Ruapehu District, in New Zealand's Manawatū-Whanganui region. It is located on the south-eastern North Island Volcanic Plateau, 130 km (81 mi) north of Palmerston North and 25 kilometres south-east of Mount Ruapehu. The town had a population of 765 in the 2018 census.
Mount Ngauruhoe is a volcanic cone in New Zealand. It is the youngest vent in the Tongariro stratovolcano complex on the Central Plateau of the North Island and first erupted about 2,500 years ago. Although often regarded as a separate mountain, geologically, it is a secondary cone of Mount Tongariro.
Tongariro National Park is the oldest national park in New Zealand, located in the central North Island. It has been acknowledged by UNESCO as a World Heritage Site of mixed cultural and natural values.
The North Island Volcanic Plateau is a volcanic plateau covering much of central North Island of New Zealand with volcanoes, lava plateaus, and crater lakes. It contains the Taupō caldera complex, Ōkataina caldera complex and Tongariro Volcanic Centre resulting in it being currently the most frequently active and productive area of silicic volcanism on Earth. New Zealand is part of the Pacific Ring of Fire.
The Whangaehu River is a large river in central North Island of New Zealand. Its headwaters are the crater lake of Mount Ruapehu on the central plateau, and it flows into the Tasman Sea eight kilometres southeast of Whanganui. Due to the high acidity of the water coming from the crater lake, water is not diverted from the headwaters for the Tongariro Power Scheme. Instead, it bypasses the Waihianoa Aqueduct via a ford.
Ruapehu District is a territorial authority in the centre of New Zealand's North Island.
The Whakapapa River in New Zealand forms from streams which trickle off the Whakapapa skifield of Mount Ruapehu and down the western slopes of the mountain. The river passes near Ōwhango, before finally merging with the Whanganui River just east of Kakahi, about 40 km (25 mi) from where it starts, which is in a 100 m (330 ft) deep gorge, at the confluence of the Whakapapaiti and Whakapapanui Streams.
The Tongariro River is a river in the North Island of New Zealand. The part of the Waikato River from the Waihohonu Stream, down to Lake Taupō, was formally named the Tongariro River in 1945. The river originates in the Central Plateau of the North Island where it is fed by numerous tributaries that flow off the surrounding hill ranges and mountains such as Mount Ruapehu. It then winds its way north, through the township of Tūrangi before entering Lake Taupō via a number of river mouths. The minimum volume of water flowing down the lower Tongariro River ranges from approximately 16 cubic metres per second (570 cu ft/s) to 21 cubic metres per second (740 cu ft/s). This volume can substantially increase due to catchment of rainfall by the surrounding mountains and hill ranges.
State Highway 49 (SH 49) is a New Zealand state highway, linking SH 4 and SH 1, via the tourist town of Ohakune. It forms the southern part of the ring road surrounding Tongariro National Park and provides access to the southern side of Mount Ruapehu and the Turoa skifield. It roughly follows the North Island Main Trunk railway.
Ngāti Rangi or Ngāti Rangituhia is a Māori iwi (tribe) of New Zealand. Contemporary settlement is mainly around Waiouru, Ohakune, and the Upper Whanganui River in the central North Island. The iwi's area of interest extends north from the Paretetaitonga peak of Mount Ruapehu, west to the Pukupuku Stream, east to the meeting of the Moawhango and Aorangi waterways, and south to the Haumakariri Stream. Ngāti Rangi trace their ancestry to Paerangi. They believe they were in New Zealand before the first migrations from Hawaiki.
The Tongariro Power Scheme is a 360 MW hydroelectricity scheme in the central North Island of New Zealand. The scheme diverts water from tributaries of the Rangitikei, Whangaehu, Whanganui, and Tongariro rivers. These rivers drain a 2,600-square-kilometre (1,000 sq mi) area including Ruapehu, Ngauruhoe, Tongariro and the western Kaimanawa Ranges. The water diverted from these rivers is sent through canals and tunnels to generate electricity at three hydro power stations, Rangipo (120 MW), Tokaanu (240 MW) and Mangaio (2 MW). The water is then discharged into Lake Taupō where it adds to the water storage in the lake and enables additional electricity generation in the succession of power stations down the Waikato River.
The Moawhango River is a tributary of the Rangitīkei River and is located the central North Island of New Zealand.
State Highway 47 (SH 47) is a New Zealand state highway in the central North Island. It provides a link from SH 4 at National Park to SH 41 at Tokaanu just west of Tūrangi.
Whangaehu is a settlement in the Rangitikei District and Manawatū-Whanganui region of New Zealand's North Island.
The seismically active southern end of the Taupō Rift beyond Mount Ruapehu has a number of mainly east to west orientated termination faults where the western wall Raurimu Fault and eastern wall Rangipo Fault terminate in the Ruapehu Graben, of the central North Island of New Zealand. In a multi-fault rupture event there is the potential for the earthquake being of 7.1 magnitude.
The Rangipo Fault is the eastern Taupō rift-bounding north–south striking normal fault complex of the Ruapehu Graben, a seismically active area of the central North Island of New Zealand to the west of Mount Ruapehu. It could be part of a 7.1 potential rupture.
The Upper Waikato Stream Fault is an eastern Taupō rift-bounding north–south striking normal fault in the Ruapehu Graben, a seismically active area of the central North Island of New Zealand to the west of Mount Ruapehu. While its own whole fault rupture potential is 6.5, such a rupture could be part of a Mw 7.1 multi-fault rupture.
