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 ...

Tongariro River
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 (such as the Whitikau, Poutu, and Mangamawhitiwhiti streams) 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 (recorded at the upper river's Poutu Intake) to (recorded at the lower river's Major Jones Pool). This volume can substantially increase due to catchment of rainfall by the surrounding mountains and hill ranges. Recreation Fishing The Tongariro River is New Zealand's most fished river, and is a drawcard for anglers the world over, who com ...

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. Geography Ruapehu is located in the centre of the North Island of New Zealand, northeast of Ohakune, New Zealand, and southwest of the southern shore of Lake Taupō, within Tongariro ...

Oruanui Eruption
The Oruanui eruption (also known as the Kawakawa eruption or Kawakawa/Oruanui event) of Taupō Volcano in New Zealand around 25,700 years before present was the world's most recent supereruption, and its largest phreatomagmatic eruption characterised to date. Geography At the time of the eruption, the sea level was much lower than at present, and for over 100,000 years the Taupō Volcano had been mainly under Lake Huka, a larger lake than the present Lake Taupō. Lake Huka was destroyed in the eruption, and other features of the local geography were changed significantly as outlined below. Eruption With a Volcanic Explosivity Index of 8, it is one of the largest eruptions ever to occur in New Zealand and the most recent supereruption. It occurred years BP in the Late Pleistocene. It generated approximately of pyroclastic fall deposits, of pyroclastic density current (PDC) deposits (mostly ignimbrite), and of primary intracaldera material, equivalent to of rhyolitic m ...

Taupō Volcano
Lake Taupō, in the centre of New Zealand's North Island, fills the caldera of the Taupō Volcano, a large rhyolitic supervolcano. This huge volcano has produced two of the world's most powerful eruptions in geologically recent times. The volcano is in the Taupō Volcanic Zone within the Taupō Rift, a region of rift volcanic activity that extends from Mount Ruapehu, Ruapehu in the south, through the Taupō District, Taupō and Rotorua Lakes, Rotorua districts, to Whakaari / White Island, in the Bay of Plenty.

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] |
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 ...

Kaimanawa Mountains
The Kaimanawa Range, officially called the Kaimanawa Mountains since 16 July 2020, is a range of mountains in the central North Island of New Zealand. They extend for 50 kilometres in a northeast–southwest direction through largely uninhabited country to the south of Lake Taupō, east of the "Desert Road". Their slopes form part of the North Island Volcanic Plateau. The New Zealand Ministry for Culture and Heritage gives a translation of "breath for food" for ''Kaimanawa''. The lands around the mountains are scrubby. To the west, where the Rangipo Desert is located, the soils are poor quality. To the east, the soils are more fertile, but the land is very rough. A population of feral horses, the Kaimanawa horses, roam free on the ranges. Unlike the majority of mountain ranges in New Zealand, the Kaimanawa Range is divided into private land. Considerable areas of the Rangipo Desert are used by the New Zealand Army for training. Demographics Kaimanawa covers and had an estimate ...

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] |

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] |
