It’s the "on-land" boundary of the Pacific and Australian Plates. The coefficient of variation is estimated at 0.41. A: The South Island of New Zealand showing major active onshore faults (black lines) and the Alpine fault which is the boundary between the Australian and Pacific plates in this location (red). Become a Study.com member to unlock this This pattern of deeper earthquakes towards the northwest of North Island reflects the northwest dip (or slope) of the boundary between the two plates (the Benioff zone). In this area the Pacific Plate and the Australian Plate are sliding past each other and the grinding of the edges is pushing up the Southern Alps. The area of volcanic activity is referred to as the Taupo Volcanic Zone (see map above).

Start studying Types of Faults and Boundaries. The type of plate boundary at the Alpine Fault is a transform boundary. 13. This molten rock rises to the surface through the thinned crust and is either erupted from volcanoes like Ruapehu, Tongariro and Ngaruhoe or sits within the crust and heats it, and the water it contains, up causing geothermal activity around Taupo and Rotorua. Shallow earthquakes tend to occur to the southeast of this seismic zone, while the deeper ones occur towards the northwest. Explore concepts. 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. Alpine Fault Alpine Fault is the on land boundary of the Pacific and Australian Plates, and is one of the world’s major geological features. The bodies of the rock in the Alpine Fault moves horizontally and vertically. 1; Wellman, 1953; De Mets et al., 2010), provide an opportunity to investigate its earthquake history and provide insight into plate boundary behavior. Conversely, in the southwest of South Island where the Australian Plate is being subducted below the Pacific Plate, the deeper earthquakes occur on the southeast edge of the seismic zone where the Benioff zone dips steeply to the southeast. The Southern Alps have been formed over millennia by upthrust from successive earthquakes on the Alpine Fault. Edit. Created by. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. The Alpine Fault is one of the world’s major geological features. At a transform boundary, two tectonic plates slide past each other. Flashcards. The uplift to the southeast of the fault is due to an element of convergence between the plates, meaning that the fault has a significant high-angle reverse oblique component to its displacement.
