Pihanga
Pihanga is a andesitic volcanic peak in the North Island Volcanic Plateau, located to the north of Mount Tongariro, between Tongariro and Lake Taupo. Lake Rotoaira lies to the south-west of Pihanga, and the smaller Lake Rotopounamu is situated on the south-western flank of the volcano, near Te Ponanga Saddle. Across the saddle to the west is the volcanic peak of Tihia. Pihanga and Lake Rotopounamu are part of the 5,129ha Pihanga Scenic Reserve, which in 1975 was added to the Tongariro National Park. Pihanga appears to have a large crater, but this is in fact the result of erosion, and the "crater" quickly narrows into a steep gorge. Geology Eruptions from Pihanga last occurred more than 20,000 years ago. The more recent eruptions are consistent with the north-north-east to south-south-west alignment of the present southern Taupo Volcanic Zone rifting. Just to the east is the Poutu Fault Zone.

Lake Rotopounamu
Lake Rotopounamu (also known as Greenstone Lake, from the Māori (lake) and (greenstone)) is a secluded lake in the Pihanga Scenic Reserve, in the Tongariro National Park in New Zealand's Central North Island. It lies at the northwest foot of Mt Pihanga, and was formed by a landslide around 10,000 years ago. The lake is fed by seven streams, but has no visible surface outflow. It is believed to drain underground. Recreation Around the lake is a scenic loop track, which can be accessed from the Pihanga Saddle road (State Highway 47) between Turangi and Tongariro Mount Tongariro (; ) is a compound volcano in the Taupō Volcanic Zone of the North Island of New Zealand.

Taupō Volcanic Zone
The Taupō Volcanic Zone (TVZ) is a volcanic area in the North Island of New Zealand that has been active for the past two million years and is still highly active. Mount Ruapehu marks its south-western end and the zone runs north-eastward through the Taupō and Rotorua areas and offshore into the Bay of Plenty. It is part of the larger Central Volcanic Region that extends further westward through the western Bay of Plenty to the eastern side of the Coromandel Peninsula and has been active for four million years. At Taupō the rift volcanic zone is widening east–west at the rate of about 8 mm per year while at Mount Ruapehu it is only 2–4 mm per year but this increases at the north eastern end at the Bay of Plenty coast to 10–15 mm per year. It is named after Lake Taupō, the flooded caldera of the largest volcano in the zone, the Taupō Volcano and contains a large central volcanic plateau as well as other landforms associated with its containing tectonic i ...

North Island Volcanic Plateau
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, Okataina caldera complex and Tongariro Volcanic Centre 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 Ngāuruhoe, and Mount Ruapehu in the south, and extends beyond Rotorua in the north reach ...

Lake Rotoaira
Lake Rotoaira (sometimes written ''Lake Roto-aira'') is a small lake to the south of Lake Taupō on the North Island Volcanic Plateau in New Zealand. It covers an area of 13 km². Lake Rotoaira is one of the few privately owned lakes in New Zealand being administered by the Lake Rotoaira Trust on behalf of its owners. An access permit must be held by those using the lake for fishing and similar activities. The lake is located in a graben between the broad volcanic dome of Mount Tongariro to the south and the smaller volcanic peak of Pihanga to the northwest. It is naturally drained by the Poutu Stream into the Tongariro River. However the Tongariro Power Scheme utilised Rotoaira as a storage lake for the Tokaanu Hydropower Station. Extensive engineering works were carried out including the diversion of a number of other streams (including Whanganui River) into Rotoaira via the Otamangakau Hydro Lake and construction of a tunnel through Pihanga to the Tokaanu Power Station ...

Poutu Fault Zone
The Poutu Fault Zone is a seismically active area of the central North Island of New Zealand. Geology The intra-rift Poutu Fault Zone extends from inland of Turangi on the shores of Lake Taupō towards Mount Ruapehu on the east side of the mountain. It has two segments known as the Poutu North fault at long and the Poutu South fault at long and 23 strands have been characterised which probably merge into a single fault plane at depth. The southern end of the Poutu North fault is in close proximity to a number of recently active vents of Mount Tongariro. The northern end of the Poutu North fault essentially passes under the volcanic peak of Pihanga. Accordingly there is the potential for both active faulting and magmatic processes to trigger earthquakes. The relative proportions contributed is important for determining earthquake associated risk and previous assumptions about magmatic processes being dominant are not the case. However magmatic activity is associated with high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Tongariro
Mount Tongariro (; ) is a compound volcano in the Taupō Volcanic Zone of the North Island of New Zealand. It is located to the southwest of Lake Taupō, and is the northernmost of the three active volcanoes that dominate the landscape of the central North Island. Geology Mount Tongariro is part of the Tongariro volcanic centre, which consists of four massifs made of andesite: Tongariro, Kakaramea-Tihia Massif, Pihanga, and Ruapehu at the southern end of the North Island Volcanic Plateau. The andesitic eruptions formed Tongariro, a steep stratovolcano, reaching a height of . Tongariro is composed of layers of both lava and tephra and the eruptions that built the current stratovolcano commenced about 275,000 years ago. Tongariro consists of at least 12 cones. Ngāuruhoe, while often regarded as a separate mountain, is geologically a cone of Tongariro. It is also the most active vent, having erupted more than 70 times since 1839, the last episode in 1973 to 1975. Activity ...

Kakaramea-Tihia Massif
The Kakaramea-Tihia Massif is an andesitic volcano in the central North Island of New Zealand. It extends from the peak of Kakaramea at in the west to the peak of Tinui at . The term Kakaramea means many colours in Maori and relates to rock/soil colour on parts of the massif so is a common place name in New Zealand. The massif is located in the North Island Volcanic Plateau, to the south of Lake Taupo. Lake Rotoaira lies to the south-east as does further away Mount Tongariro and to the east is Pihanga on the other side of the Te Ponanga Saddle from Tihia. Geology Eruptions from the Kakaramea-Tihia Massif last occurred more than 20,000 years ago and the most recent appears to be from a vent west-south-west of Tihia. The older formations were from vents aligned north-west to south-east but the more recent eruptions are consistent with the north-north-east to south-south-west alignment of the present southern Taupo Volcanic Zone rifting. It is adjacent to the Waihi Fault Zone which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Taranaki
Mount Taranaki (), also known as Mount Egmont, is a dormant stratovolcano in the Taranaki region on the west coast of New Zealand's North Island. It is the second highest point in the North Island, after Mount Ruapehu. The mountain has a secondary cone, Fanthams Peak ( mi, Panitahi), , on its south side. Name The name ''Taranaki'' comes from the Māori language. The Māori word means mountain peak, and is thought to come from , meaning "shining", a reference to the snow-clad winter nature of the upper slopes. It was also named and by iwi who lived in the region in "ancient times". Captain Cook named it Mount Egmont on 11 January 1770 after John Perceval, 2nd Earl of Egmont, a former First Lord of the Admiralty who had supported the concept of an oceanic search for '' Terra Australis Incognita''. Cook described it as "of a prodigious height and its top cover'd with everlasting snow," surrounded by a "flat country ... which afforded a very good aspect, being clothed with ...

Ngaere
Ngaere is a village situated on State Highway 3, south of Stratford, New Zealand. The name "Ngaere" literally means "swamp" in English, and before settlement, the area was covered by a vast and ancient wetland. For a time, the name was spelt "Ngaire", but it was changed to its Maori spelling in 1909. Attractions "Ngaere Gardens", which once hosted a menagerie of exotic animals, was a popular picnic spot for early 20th century families. Several attempts at resurrecting the gardens have been to no avail. The gardens have now been cleared, and all that remains now is the large lake, and a number of mature exotic trees. Another well-known landmark is the Ngaere dairy factory, founded in 1914. It produced its own brand of cheese called "Triumph". The Ngaere factory closed in 1973, after the Ngaere dairy cooperative merged into the Taranaki dairy cooperative. Since its closure, the factory has been put to many uses - as a clothing factory, an indoor cricket arena, a rave dan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
