The Wellington Fault is an active seismic fault in the southern part of the North Island of New Zealand. It is a dextral (right-lateral) strike-slip fault with variable amounts of vertical movement causing uplift to the northwest, as expressed by a series of ranges.
The Geological Survey of New Zealand now known as GNS Science has done extensive mapping through New Zealand at 1:250,000 and 1:50:000 scales. The most modern map series are the "QMAPs" at 1:250,000. [47] New Zealand's geological research is published by GNS Science, in the New Zealand Journal of Geology and Geophysics, and internationally.
The North Island Fault System (NIFS) (also known as North Island Dextral Fault Belt or North Island Shear Belt [1]) is a set of southwest–northeast trending seismically-active faults in the North Island of New Zealand that carry much of the dextral (right lateral) strike-slip component of the oblique convergence of the Pacific Plate with the Australian Plate.
The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island, being about 600 km (370 mi). [a] long, and forms the boundary between the Pacific plate and the Australian plate. [4] The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes.
The Otago fault system (also known as Otago reverse fault province) contains multiple faults with the potential to have rupture events greater than M w 7 in magnitude. [2] [3] These are parallel to, and to the east of the Alpine Fault in the south eastern part of the South Island of New Zealand. It accommodates about 2 mm (0.079 in)/year of ...
The Auckland regional geologic faults have low seismic activity, [6] [1] compared to much of New Zealand, but do result in an earthquake risk to the Auckland metropolitan area, New Zealand's largest city.
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 ...
