Between 25 and 12 million years ago the movement on the proto-Alpine Fault was exclusively strike-slip. The Southern Alps had not yet formed and most of New Zealand was covered in water. [10] Then uplift slowly began as the plate motion became slightly oblique to the strike of the Alpine Fault.
The geology of New Zealand is noted for its volcanic activity, earthquakes and geothermal areas because of its position on the boundary of the Australian Plate and Pacific Plates. New Zealand is part of Zealandia, a microcontinent nearly half the size of Australia that broke away from the Gondwanan supercontinent about 83 million years ago. [1]
The Pacific plate (carrying the city of Los Angeles) is moving northwards with respect to the North American plate. The Queen Charlotte Fault on the Pacific Northwest coast of North America The Motagua Fault , which crosses through Guatemala , is a transform boundary between the southern edge of the North American plate and the northern edge of ...
The Hikurangi Subduction Zone is an active subduction zone extending off the east coast of New Zealand's North Island, where the Pacific and Australian plates collide. [2] [3] The subduction zone where the Pacific Plate goes under the Kermadec Plate offshore of Gisborne accommodates approximately 6 cm/year (2.4 in/year) of plate movement while off the Wairarapa shore this decreases to perhaps ...
Major active fault zones of New Zealand showing variation in displacement vector of Pacific plate relative to Australian plate along the boundary. The Marlborough fault system (also known as Marlborough tectonic domain [2]) is a set of four large dextral strike-slip faults and other related structures in the northern part of the South Island, New Zealand, which transfer displacement between ...
The East Pacific Rise near Easter Island is the fastest spreading mid-ocean ridge, with a spreading rate of over 15 cm/yr. [2] The Pacific plate moves generally towards the northwest at between 7 and 11 cm/yr while the Juan De Fuca plate has an east-northeasterly movement of some 4 cm/yr. [3]
A significant amount of the movement between the two plates is accommodated by lateral sliding of the Indo-Australian plate north relative to the Pacific plate. The plate boundary forms the nearly 800 kilometres (500 mi) long Alpine Fault .
