You can pick out the line of the Alpine Fault on this satellite image of the South Island. [6], The Pacific Plate originated at the triple junction of the three main oceanic plates of Panthalassa, the Farallon, Phoenix, and Izanagi Plates, around 190 million years ago.The plate formed because the triple junction had converted to an unstable form surrounded on all sides by transform faults, due to the development of a kink in one of the plate boundaries. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. The Alpine Fault. [3], The Pacific Plate has the distinction of showing one of the largest areal sections of the oldest members of seabed geology being entrenched into eastern Asian oceanic trenches. Answer to: Is the Alpine Fault convergent, divergent, or transform? There are currently three What’s On Our Plates? Please note: The What’s On Our Plates? In the simple, introductory textbook explanation, the Alpine Fault plate boundary system through South Island, New Zealand is simply a "San Andreas-like continental transform that links two subduction zones. The Alpine fault is the Pacific-Australian plate boundary in the South Island of New Zealand. A smaller number connect mid-ocean ridges and subduction zones. The San Andreas fault of California is a prime example of a continental transform boundary; others are the North Anatolian fault of northern Turkey, the Alpine fault crossing New Zealand, the Dead Sea rift in the Middle East, the Queen Charlotte Islands fault off western Canada, and the Magellanes-Fagnano fault system of South America. Visible from space, it marks the boundary between the Pacific and Australian crustal plates … At 103 million km2 (40 million sq mi), it is the largest tectonic plate. The Alpine Fault forms part of the on-land Pacific-Australian plate boundary. A: The Hikurangi Trench and Alpine Fault form part of the Australian-Pacific plate boundary that transects New Zealand. A geologic map of the Pacific Ocean seabed shows not only the geologic sequences, and associated Ring of Fire zones on the ocean's perimeters, but the various ages of the seafloor in a stairstep fashion, youngest to oldest, the oldest being consumed into the Asian oceanic trenches. The "Pacific Triangle", the oldest part of the Pacific Plate, created during the initial stages of plate formation, is located just east of the Mariana Trench. the plate boundary deformation from the Alpine fault to the Hikurangi suhduction zone and the Wairau section is a relic feature carrying only about 10% of the inter-plate The Alpine Fault runs right through the heart of New Zealand's glacier county on the country's south island. Transform Plate Boundaries are locations where two plates slide past one another. The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. The northern side is a convergent boundary subducting under the North American Plate forming the Aleutian Trench and the corresponding Aleutian Islands. The Alpine Fault is one of the world's major plate boundaries and New Zealand's most hazardous earthquake-generating fault. Alpine Fault movement. LEITNER ETAL. The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand.

Although predominantly associated with subduction zones, tremor also occurs along the deep extension of the strike-slip San Andreas Fault. The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian Plate subducts under the Pacific Plate forming the Puysegur Trench. [citation needed], The western side, the plate is bounded by the Okhotsk Plate at the Kuril-Kamchatka Trench and the Japan Trench, forms a convergent boundary by subducting under the Philippine Sea Plate creating the Mariana Trench, has a transform boundary with the Caroline Plate, and has a collision boundary with the North Bismarck Plate. [4] Bird considers them to be unconnected. The Alpine Fault is a geological fault, specifically a right-lateral strike-slip fault, that runs almost the entire length of New Zealand’s South Island. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island (c. 480 km) and forms the boundary between the Pacific Plate and the Indo-Australian Plate. It includes an oceanic transform (the Macquarie Ridge), two oppositely verging subduction zones (Puysegur and Hikurangi), and a transpressive continental transform, the Alpine Fault through South Island, New Zealand.
