Pihanga
Pihanga is a andesitic volcanic peak in the North Island Volcanic Plateau, located to the north of Mount Tongariro, between Tongariro and Lake Taupō. The nearest town to Pihanga is Tūrangi. 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. An age of 123 ± 10 ka has been challenged and potentially redating suggests first formation greater than 180,000 years ago. The more recent eruptions are consistent with the north-north-east to south-south-west alignment of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taupō Volcanic Zone
The Taupō Volcanic Zone (TVZ) is a volcano, volcanic area in the North Island of New Zealand. It has been active for at least 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 a larger Central Volcanic Region that extends to the Coromandel Peninsula and has been active for four million years. The zone is contained within the Tectonics, tectonic intra-arc continental Taupō Rift and this rift volcanic zone is widening unevenly east–west, with the greatest rate of widening at the Bay of Plenty coast, the least at Mount Ruapehu and a rate of about per year at Taupō. The zone is named after Lake Taupō, the flooded caldera of the largest volcano in the zone, the Taupō Volcano and contains a large central North Island Volcanic Plateau, volcanic plateau as well as other landforms. Activity There are numerous vol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Rotopounamu
Lake Rotopounamu (also known as Greenstone Lake, from the Māori language, 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 Tūrangi and Tongariro. Walking this track takes about two hours. References Tongariro Volcanic Centre Taupō District Lakes of Waikato, Rotopounamu Tongariro National Park {{Waikato-geo-stub ...

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. The Tongariro Power Scheme utilises Rotoaira as a storage lake for the Tokaanu Power Station. Extensive engineering works were carried out between 1964 and 1971 diverting a number of streams (including Whanganui River) into Rotoaira via Lake Otamangakau and construction of a tunnel through Pihanga to the Tokaanu Power Station. The lake original ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Taranaki
Mount Taranaki (), officially Taranaki Maunga and also known as Mount Egmont, is a dormant stratovolcano in the Taranaki region on the west coast of New Zealand's North Island. At , it is the second highest mountain in the North Island, after Mount Ruapehu. It has a secondary cone, Fanthams Peak (), , on its south side. Name The name ''Taranaki'' is from the Māori language. The mountain was named after Rua Taranaki, the first ancestor of the iwi (tribe) called Taranaki, one of several iwi in the region. The Māori word ''tara'' means mountain peak, and ''naki'' may come from ''ngaki'', meaning "clear of vegetation." It was also named ("ice mountain") and ("hill of Naki") 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 prodig ... [...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.

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 Māori 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 Taupō. 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 commenced at 229,000 ± 1,000 years ago. A more recent dated eruption was from Tihia, at 198,000 ± 23,000 years ago, with even more recent activity possible to Tihia's south-west. The older formations are 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 Tau ...

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. Ngauruhoe, 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. Activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tūrangi
Tūrangi is a small town on the west bank of the Tongariro River, 50 kilometres south-west of Taupō on the North Island Volcanic Plateau of New Zealand. It was built to accommodate the workers associated with the Tongariro Power Scheme, Tongariro hydro-electric power development project and their families. The town was designed to remain as a small servicing centre for the exotic forest plantations south of Lake Taupō and for tourists. It is well known for its trout fishing and calls itself "the trout fishing capital of the world". The major Māori people, Māori ''hapū'' (tribe) of the Tūrangi area is Ngāti Tūrangitukua. Geography The Tūrangi area covers some 2273 km², and is located close to the edge of the Kaimanawa Ranges and ten kilometres north of the stretch of New Zealand State Highway 1, State Highway 1 known as the ''Desert Road''. The streets around Tūrangi in autumn are lined with "brilliant" foliage. Built on the banks of the Tongariro River, Tūran ...

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 Tūrangi 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 highe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
