Taupō Rift Termination Faults
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 (Desert Road 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 magnitude. The faults can be classified as belonging to three normal fault sets: # Ruapehu Graben NNE‐trending faults #* Raurimu Fault - see separate article #* Rangipo Fault (Desert Road Fault) - see separate article #* Mostly uncharacterised faults under Mount Ruapehu # Ohakune‐Raetihi fault set that is wide of E‐W to ESE‐WNW‐trending faults #* Ohakune Fault #* Raetihi North and South faults #* Waipuna Fault #* Oruakukuru Fault #* Rangiahu Fault #* Maketu Stream Fault (Maketu Trace) # Karioi fault set that is wide of NE‐trending faults #* Karioi Fault #* Wahianoa Fault #* Snowg ...

Ohakune
Ohakune is a small town at the southern end of Tongariro National Park, close to the southwestern slopes of the active volcano Mount Ruapehu, in the North Island of New Zealand. A rural service town known as New Zealand's Carrot Capital, Ohakune is a popular base in winter for skiers using the ski resorts, ski fields (particularly Turoa) of Mount Ruapehu and in summer for Tramping in New Zealand, trampers hiking the Tongariro Alpine Crossing. Toponymy The Ngāti Rangi iwi say the Māori language name ''Ohakune'' comes from the phrase "''he Ohakune ki te ao''", which broadly means "an opening to a new world" and refers to the descent from Mount Ruapehu into the valley and swamps of the area. In 2019 the New Zealand Geographic Board changed the official name to ''Ōhakune'', indicating that the first letter was a long vowel, but swiftly reverted to ''Ohakune'' without a macron when Ngāti Rangi objected.

Rangipo Fault
The Rangipo Fault (also known in the past as Desert Road Fault, Whangaehu River Fault, 'Whangaehu 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 potential rupture. Geography It is located near the eastern side of the Tongariro National Park, mainly in the Rangipo Desert, and traces have been now characterised on both sides of State Highway 1 where it is known as "''the Desert Road''" extending for at least . The northern surface traces of the fault commences just south of the Waipakihi Road to the east of the Desert Road and it extends south of the Waiouru Military Camp to almost the south west corner of the army training area. Geology The Upper Waikato Stream Fault is the eastern wall fault to its immediate north and it has been postulated that whole fault rupture of that fault, the Rangip ...

Tongariro Volcanic Centre
The North Island Volcanic Plateau (often called the Central Plateau and occasionally the Waimarino 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. Location and description The plateau is approximately east–west and the north–south distance is about . Extensive ignimbrite sheets spread east and west from the Central Taupō Volcanic Zone, centred on the huge active supervolcanic caldera of Lake Taupō, now the largest lake in New Zealand. This last erupted less than 2000 years ago. The volcanic area includes the three active peaks of Mount Tongariro, Mount Ngauruhoe, and Mount Ruapehu in the south, and extends beyond Rotorua in the n ...

Seismic Faults Of New Zealand
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies. It also includes studies of the environmental effects of earthquakes such as tsunamis; other seismic sources such as volcanoes, plate tectonics, glaciers, rivers, oceanic microseisms, and the atmosphere; and artificial processes such as explosions. Paleoseismology is a related field that uses geology to infer information regarding past earthquakes. A recording of Earth's motion as a function of time, created by a seismograph is called a seismogram. A seismologist is a scientist who works in basic or applied seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (), Anax ...

Before Present
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year". The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must account for when using radiocarbon dating for dates of origin that may fall after this year. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation "RCYBP" stands for the explicit "radio carbon years before present". Usage The BP scale is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Waikato Stream Fault
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 , such a rupture could be part of a multi-fault rupture. Geography It is located near the eastern side of the Tongariro National Park, and its surface traces commence to the east of State Highway 1 where it is known as "''the Desert Road''" and extend to the north east for crossing the top of the Tongariro River and for a short distance into the foothills of the Kaimanawa Mountains. Geology The Upper Waikato Stream Fault is one of the eastern wall faults of the Ruapehu Graben and it is immediately to the north of the longer Rangipo Fault. Its alignment has it as a potential continuation from the west of the Wahianoa Fault. This intersection of the three faults could result in a 7.1 MW event if all three ...

Waiouru Military Camp
Waiouru Military Camp is a camp of the New Zealand Army in the central North Island of New Zealand near Waiouru. All New Zealand Army soldiers complete their initial basic training, the All Arms Recruit Course (AARC), at Waiouru Military Camp. The camp is also the site of the army marae. The marae is the home of ''Ngāti Tūmatauenga'', literally 'the tribe of the God of War', the Māori name for the New Zealand Army. History The New Zealand government chose the sheep station at Waiouru as the location of a North Island training area for its Territorial Forces in the 1930s. The sheep station had large areas of inexpensive open land, and existing road and rail access to the North Island coastline. The artillery was the first branch of the New Zealand Army to use Waiouru. In 1937, Waiouru farmhand Cedric Arthur wrote: :''The Military (artillery) Camp is here again for its annual big shoot, so Waiouru is exceedingly busy with huge lorries, tractors, guns and horses, not to mentio ...

Mangawhero River
The Mangawhero River is in the North Island of New Zealand. It drains the south-western slopes of Mount Ruapehu, passes through Ohakune before discharging into the Whangaehu River to the south-west of Mangamahu. History The name Mangawhero means comes from the Māori word ''manga'' meaning "stream" and ''whero'' meaning "red". The river has been used for fishing, agricultural irrigation and domestic water supply. On 8 September 1979 up to of heating oil were split into the river from the Turoa ski field. Course The source of the Mangawhero River is located on the slopes of Mt Ruapehu at elevation of approximately . The river begins within the area of the Tūroa skifield and flows down the slopes of the mountain in a south west direction. The Ohakune Mountain Road, built during the 1950s and 60s, follows the river valley up to the skifield. The high Mangawhero Falls is located in this top section of the river and is accessible via a short walk from Ohakune Mountain Roa ...

State Highway 4 (New Zealand)
State Highway 4 is the shortest of New Zealand's eight national highways. It runs north-south across rugged hill country, forming a short cut between two points on State Highway 3 thereby avoiding Taranaki and the coasts of the North and South Taranaki Bights. Distances are measured from north to south. For most of its length SH4 is a two-lane single carriageway, with at-grade intersections and property accesses, both in rural and urban areas. The NZ Transport Agency (NZTA) classifies SH 4 as a primary collector road, except between National Park (SH 47) and Tohunga Junction (SH 49) where it is classified an arterial road. Route The highway commences from a junction on SH 3 11 km south of Te Kūiti. It heads south-southeast, climbing initially, then descending along the winding valleys of the Ōhura and Ongarue Rivers, two tributaries of the Whanganui. The Ongarue joins the Whanganui close to Taumarunui, and here the highway turns east briefly, ascending ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohakune Volcanic Complex
The Ohakune volcanic complex (Ohakune craters, Rochfort Crater) is a small extinct monogenetic volcano south-west of Mount Ruapehu and just north of the town of Ohakune in Manawatū-Whanganui, New Zealand. It is in the area of the southernmost volcanic activity in the Taupō Rift and located adjacent to the potentially active Ohakune Fault. Geography The complex is located at the north-western corner of the town of Ohakune at the Tongariro National Park boundary and bisected by the main trunk railway line as it leaves the town to the north-west. Although the Ohakune volcanic complex is also known as the Rochfort Crater, this is the geographical name for the largest of several craters associated with the complex. South of the main trunk railway line is the main scoria cone that reaches a height of and has been quarried on its south-eastern flank. There are a couple of depressions south of the railway line adjacent to the town. North of the line the volcano is mainly fores ...
