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 ...

Rangipo Desert
Te Onetapu (), commonly known as the Rangipo Desert (), is a barren desert-like environment located in New Zealand, located in the Ruapehu District on the North Island Volcanic Plateau; to the east of the three active peaks of Mount Tongariro, Mount Ngauruhoe, and Mount Ruapehu, and to the west of the Kaimanawa Range. Etymology Two main names have been given to the desert, both of which are derived from te reo Māori and describe the area's history. The first of these, Te Onetapu, is derived from the words - beach or sand, and - sacred. This name refers to the death of Taiteariki, an ancestor of the Ngāti Rangi iwi who was killed at a location in the desert in early Māori history after conflict arose between him and two children of Houmea, Tura and Rotuia. Following Pākehā settlement and expansion into the region, the desert became known as Rangipo, from the Māori words , meaning sky, and , meaning night or darkness. This name references the story of Ngātoro-i-rangi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
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 ...

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 ...

State Highway 1 (New Zealand)
State Highway 1 (SH 1) is the longest and most significant road in the New Zealand road network, running the length of both main islands. It appears on road maps as SH 1 and on road signs as a white number 1 on a red shield, but it has the official designations SH 1N in the North Island, SH 1S in the South Island. SH 1 is long, in the North Island and in the South Island. Since 2010 new roads have reduced the length from . For the majority of its length it is a two-lane single carriageway, with at-grade intersections and property accesses, in both rural and urban areas. These sections have some passing lanes. Around of SH 1 is of motorway or expressway standard : in the North Island and in the South Island. Route North Island (SH 1N) SH 1 starts at Cape Reinga, at the northwestern tip of the Aupōuri Peninsula, and since April 2010 has been sealed (mainly with either chipseal or asphalt) for its entire length. From Waitiki Landing south of Cape Reinga, SH 1 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Ruapehu
Mount Ruapehu (; English ) is an active stratovolcano at the southern end of the Taupō Volcanic Zone and North Island North Island Volcanic Plateau, volcanic plateau in New Zealand. It is northeast of Ohakune and southwest of the southern shore of Lake Taupō, within Tongariro National Park. The North Island's major ski resorts and only glaciers are on its slopes. Ruapehu, the largest active volcano in New Zealand, has the highest point in the North Island and has three major peaks: Tahurangi (2,797 m), Te Heuheu (2,755 m) and Paretetaitonga (2,751 m). The deep, active volcanic crater, crater is between the peaks and fills with water between major eruptions, being known as Crater Lake (). The name ''Ruapehu'' means "pit of noise" or "exploding pit" in Māori language, Māori.

Taupō Rift
The Taupō Rift is the seismically active rift valley containing the Taupō Volcanic Zone, central North Island of New Zealand. Geology The Taupō Rift (Taupo Rift) is a intra-arc continental rift resulting from an oblique convergence in the Hikurangi subduction zone. The present young, modern Taupō Rift is defined by events between 25,000 and 350,000 years and the old Taupō Rift system, which can be defined by a gravity anomaly, is now located more to the north being created between 350,000 and 2 million years and is about wide. Consensus does not yet exist with regard to the cause of the Taupō Rift's extension or the exceptional volcanic productivity of the associated Taupō Volcanic Zone. Its geology and landforms are of worldwide interest, and it contains multiple significant faults and volcanoes, with some of the volcanoes having potential for worldwide impact. Volcanic context The recent volcanism of the Taupō Volcanic Zone has been divided into three segments, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
