North Island Fault System
The North Island Fault System (also known as North Island Dextral Fault Belt or NIFS) is a set of southwest–northeast trending seismically-active faults in the North Island of New Zealand that carry most of the dextral (right lateral) strike-slip component of the oblique convergence of the Pacific Plate with the Australian Plate. The faults include the Wairarapa Fault and Wellington Fault to the southwest, the Ruahine and Mohaka Faults in the central section and the Waimana, Waiotahi, Whakatane and Waiohau Faults to the northeast. Most of the fault system consists of dextral strike-slip faults, although towards its northeastern end the trend swings to more S-N trend and the faults become mainly oblique normal in sense as the zone intersects with the Taupo rift zone. This fault zone accommodates up to 10 mm/yr of strike-slip displacement. Faults The North Island Fault System consists of eight main fault strands and many smaller related faults.

North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in 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 (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zhan ...

Woodville, New Zealand
Woodville, previously known as The Junction is a small town in the southern North Island of New Zealand, 75 km north of Masterton and 25 km east of Palmerston North. The 2013 census showed that 1401 people reside in Woodville. The town is in the Tararua District and the Manawatū-Whanganui region, although it has strong ties with the Hawke's Bay region, of which it was once a part, but is often considered to be the northern boundary of Wairarapa. It is within the catchment area of the Manawatu River. Geography Woodville covers a land area of 4.04 km². Only a few kilometres west of Woodville, the Manawatu River runs from east to west and cuts a deep gorge through the mountains, effectively slicing a mountain range in two. It is unusual geology as the river flows east towards the Pacific coast of the lower North Island, then cuts back west through the gorge and flows out into the Tasman Sea near Foxton. Known by Māori as Te Apiti, the gorge itself features in M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cook Strait
Cook Strait ( mi, Te Moana-o-Raukawa) separates the North and South Islands of New Zealand. The strait connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast. It is wide at its narrowest point,McLintock, A H, Ed. (1966''Cook Strait''from An Encyclopaedia of New Zealand, updated 18-Sep-2007. Note: This is the distance between the North Island and Arapaoa Island; some sources give a slightly larger reading of around , that between the North Island and the South Island. and is considered one of the most dangerous and unpredictable waters in the world. Regular ferry services run across the strait between Picton in the Marlborough Sounds and Wellington. The strait is named after James Cook, the first European commander to sail through it, in 1770. In Māori it is named ''Te Moana-o-Raukawa'', which means ''The Sea of Raukawa''. Raukawa is a type of woody shrub native to New Zealand. History Approximately 18,000 years ago during the Last Gla ...

1855 Wairarapa Earthquake
The 1855 Wairarapa earthquake occurred on 23 January at about 9.17 p.m., affecting much of the Cook Strait area of New Zealand, including Marlborough in the South Island and Wellington and the Wairarapa in the North Island. In Wellington, close to the epicentre, shaking lasted for at least 50 seconds. The moment magnitude of the earthquake has been estimated as 8.2, the most powerful recorded in New Zealand since systematic European colonisation began in 1840. This earthquake was associated with the largest observed movement on a strike-slip fault, maximum . It has been suggested that the surface rupture formed by this event helped influence Charles Lyell to link earthquakes with rapid movement on faults. Tectonic setting New Zealand lies along the boundary between the Australian and Pacific Plates. In the South Island most of the relative displacement between these plates is taken up along a single dextral (right lateral) strike-slip fault with a major reverse component, t ...

Rangitaiki River
The Rangitaiki River is the longest river in the Bay of Plenty region in New Zealand's North Island. It is long, and rises inland from northern Hawkes Bay to the east of the Kaingaroa Forest. The Rangitaiki catchment covers an area of 3005 km. It flows in a generally northeastward direction, passing through the town of Murupara and skirting close to the western edge of Te Urewera National Park before turning northwards, flowing past Edgecumbe and into the Bay of Plenty close to Thornton. There are two man-made lakes on the Rangitaiki formed by hydro-electric dams, Lake Āniwaniwa (formerly Lake Aniwhenua). and Lake Matahina. History In April 2017, remnants of Cyclone Debbie caused heavy rainfall in the region. At 8:30 am on April 6, water from the Rangitaiki River breached the College Road floodwall at Edgecumbe, causing widespread flooding across the township. A state of emergency was declared for the Whakatane District, and around 2,000 people were evacuated to Ka ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dip-slip
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...
