Raurimu Fault
The Raurimu Fault is the western 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. Geography It is located near the western side of the Tongariro National Park, mainly in the Erua Forest, where it is along the western Waimarino Stream valley. The northern surface traces of the fault commence near the Raurimu Spiral and the most southern surface is over to the south just to the east of the township of Raetihi. Geology The northern end of the fault is intersected at the township of National Park by the National Park Fault which is the more northern Taupō Rift western wall fault. Lahar deposits of late Pleistocene (20,000 to 60,000 years ago) are offset by up to . At its southern end the fault alignment is crossed by the east west Ohakune Fault which creates just to the east of Ohakune a quite complex normal fault structure. The north sou ...

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 ...

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.

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

National Park Fault
The National Park Fault is the western Taupō rift-bounding NNE-striking normal fault complex of the Tongariro Graben, a seismically active area of the central North Island of New Zealand south of Lake Taupō that contains Mount Tongariro. Geography It is located near the western side of the Tongariro National Park. The northern surface traces of the fault zone are found on the slopes of Kuharua, a high rhyolitic volcano and extend southwards around Lake Otamangakau and Lake Te Whaiau, lakes developed as part of the Tongariro Power Scheme. The western traces here are just to the west of the mutual dams of these lakes on the eastern slopes of the Maungakatote andesitic volcano and then peter out. The definitive fault surface trace commences in the hills near the headwaters of the Okupata stream just to the west of State Highway 47 and extends south close on to National Park township just to the south of the Railway Station.

National Park, New Zealand
National Park (officially Waimarino) is a small town on the North Island Volcanic Plateau, North Island Central Plateau in New Zealand. Formerly known as National Park Village, it is the highest urban township in New Zealand, at 825 metres. The village has great views of Mount Tongariro, Mount Ngauruhoe (Mount Doom in the The Lord of the Rings (film series), ''Lord of the Rings'' film trilogy), and Mount Ruapehu. Toponymy Originally the town was known as Waimarino (calm waters). In 1926, the New Zealand Railways renamed the railway station as National Park. This was to avoid confusion with other Waimarino entities, and also the name had come into common usage from its location close to Tongariro National Park. This change has since been confusing, as there are now many National Parks in New Zealand. After a three month nation-wide consultation culminated in 2,582 submissions including from a number of local iwi, residents, the applicant iwi Te Korowai o Wainuiārua. ...

Raetihi
Raetihi, a small town in the centre of New Zealand's North Island, is located at the junction of New Zealand state highway network, State Highways 4 and 49 in the Manawatū-Whanganui region. It lies in a valley between Tongariro National Park, Tongariro and Whanganui National Park, Whanganui National Parks, 11 kilometres west of Ohakune's ski fields. Early history and economy Evidence of Māori people living here in the fourteenth century has been found. Ngāti Uenuku dwelled at Raetihi and Waimarino (known now as National Park, New Zealand, National Park, located approximately 35 kilometres/22 miles north on Highway 4). There is little evidence of large permanent settlements but hunting parties were common during warmer months. In 1887 the Government purchased the Waimarino block from local Māori, and the first European settlement, at Karioi, involved setting sheep to graze on open Tussock (grass), tussock land. Between 1908 and 1947 the area provided 700 million superficia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raurimu Spiral
The Raurimu Spiral, is a single-track Spiral (railway), railway spiral, starting with a Horseshoe curve (transportation), horseshoe curve, overcoming a height difference, in the central North Island of New Zealand, on the North Island Main Trunk railway (NIMT) between Wellington and Auckland. It is a notable feat of civil engineering, having been called an "engineering masterpiece." The Institute of Professional Engineers of New Zealand has designated the spiral as a significant engineering heritage site. Background During the construction of the central section of the North Island Main Trunk, a major obstacle arose: how to cross the steep slopes between the North Island Volcanic Plateau to the east and the valleys and gorges of the Whanganui River to the west? South of Taumarunui, the terrain is steep, but not unmanageable, with the exception of the stretch between Raurimu and National Park, New Zealand, National Park, where the land rises too steeply for a direct rail ...
