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] |
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.

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, 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 reaching ...

Volcanoes Of Waikato
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

New Zealand Lesser Short-tailed Bat
The New Zealand lesser short-tailed bat (''Mystacina tuberculata'') is a small-sized omnivorous mammal endemic to the islands of New Zealand. It is one of two extant and three overall terrestrial mammal species unique to New Zealand. The NZ lesser short-tailed bat's closest relative, ''M. robusta'', was last seen in 1965 and is presumed extinct due to intense predation from ship rats introduced in the last few centuries. These bats are also commonly referred to as pekapeka, their Te Reo Māori name. Lesser short-tailed bats have unique adaptations that differentiate them from bats found in other parts of the world. For example, they are fully capable of moving along the ground to search for food, and the males sing to attract partners, taking turns to do so. Lesser short-tailed bats are a vulnerable species, so extensive conservation work and research are being done to prevent extinction. Taxonomy and evolution Taxonomic classification ''Mystacina tuberculata'' are members of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dactylanthus Taylorii
''Dactylanthus taylorii'', commonly known in English as wood rose and in Māori as te pua o te rēinga, is a fully parasitic flowering plant, the only one endemic to New Zealand. The host tree responds to the presence of ''Dactylanthus'' by forming a burl-like structure that resembles a fluted wooden rose (hence the common name). When the flowers emerge on the forest floor, they are pollinated by a ground-foraging species of native bat. Description ''Dactylanthus taylorii'' is a round, warty, tuber-like stem (up to 50cm wide) or haustorium with no roots, which draws nutrients from the roots of its host. Its leaves do not photosynthesise, and are reduced to floral bracts. Some plants have been aged in excess of 30 years old. ''Dactylanthus'' prefers damp but not waterlogged soil, and is often found at the head of small streams. It parasitises about 30 species of native hardwood trees and shrubs, preferring those growing in secondary forest on the margin of mature podocarp forest ...

Waihi Fault Zone
The Waihi Fault Zone is a seismically active area of the central North Island of New Zealand whose earthquakes have been associated with significant loss of life. Geology The intra-rift Waihi Fault Zone extends at least from Little Waihi at Lake Taupō towards Mount Ruapehu on the west side of the mountain. It has two segments known as the Waihi North fault and the Waihi South fault and 19 fault strands (three of which were previously known as the Taurewa Fault). Together they make up the south western intra-rift faults of the Tongariro Graben in the Taupō Rift. The northern part of the Waihi South fault which is about long is just to the west of the recently active vents of Mount Tongariro Mount Tongariro (; ) is a compound volcano in the Taupō Volcanic Zone of the North Island of New Zealand.

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 h ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

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 ...
