alpine fault what plate boundary
Find out how it was discovered and learn what science can tell us about Alpine Fault earthquakes. You can actually stand with each foot on a separate tectonic plate! [5], The north-eastern side is a divergent boundary with the Explorer Plate, the Juan de Fuca Plate and the Gorda Plate forming respectively the Explorer Ridge, the Juan de Fuca Ridge and the Gorda Ridge. We recommend using Google Chrome, the maps will not work in Internet Explorer. [citation needed], The southern side is a divergent boundary with the Antarctic Plate forming the Pacific-Antarctic Ridge. The Alpine Fault is one of the world's most intensively studied faultlines. The northern side is a convergent boundary subducting under the North American Plate forming the Aleutian Trench and the corresponding Aleutian Islands. 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. AF8 aims to increase awareness, enable conversation and build societal preparedness to natural hazard events in the South Island. 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. The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. Visible from space, it marks the boundary between the Pacific and Australian crustal plates … is a set of multimedia learning modules designed to enable anyone to explore Aotearoa New Zealand’s active plate boundary online, including the Alpine Fault and Hikurangi subduction zone. 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. In the south of the Island, it joins the east-directed Fiordland subduction zone while in the north, it splits into several strands that link with the west-directed North Island subduction zone. The type of plate boundary at the Alpine Fault is a transform boundary. At a transform boundary, two tectonic plates slide past each other. Nabelek, John L. Abstract. learning modules, with more coming soon. 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. Due to its relative geometric simplicity, high slip rate, and quasi-regular earthquake recurrence, the AF is a paradigm for characterizing “ideal” plate boundary behavior. A smaller number connect mid-ocean ridges and subduction zones. There are currently three What’s On Our Plates? In the region of New Zealand, the 3000 km long Australia-Pacific plate boundary extends from south of Macquarie Island to the southern Kermadec Island chain. In between the Hikurangi Subduction Zone and the Alpine Fault is a broad area of complex active faults, called the Marlborough Fault System. Geologists drilling deep into the Alpine Fault are hoping to understand what goes on before a major plate boundary fault ruptures in an earthquake. Take a tour along the Alpine Fault, Aotearoa New Zealand’s on-land plate boundary and one of the longest natural straight lines in the world! The Discovery Tour begins at the Alpine Fault Tours shop in Whataroa. The Alpine Fault of New Zealand is an example of _____ plate boundary A) A continental transform The gently sloping and fast-spreading parts of the mid-ocean ridge are called _____ The south-eastern side is a divergent boundary with the Nazca Plate forming the East Pacific Rise. The type of plate boundary at the Alpine Fault is a transform boundary. ... prepare to drill a deep borehole into the fault early next year to study processes taking place at depth inside a major plate boundary fault. The Alpine Fault is one of the world's most intensively studied faultlines. [citation needed], In the south-west, the Pacific Plate has a complex but generally convergent boundary with the Indo-Australian Plate, subducting under it north of New Zealand forming the Tonga Trench and the Kermadec Trench. The Pacific Plate is almost entirely oceanic crust, but it contains some continental crust in New Zealand, Baja California, and coastal California. The first three modules have been aligned to Level 4-6 Achievement Objectives from the Science Learning Area of the New Zealand Curriculum and are accompanied by a Teacher Guide to support their use in the classroom. The What’s On Our Plates? AF8 [Alpine Fault Magnitude 8] is an award-winning programme of scientific modelling, response planning and community engagement designed to build a collective resilience and preparedness to the next Alpine Fault earthquake event. [citation needed]. is a set of multimedia learning modules designed to enable anyone to explore Aotearoa New Zealand’s active plate boundary online, including the Alpine Fault and Hikurangi subduction zone. Answer to: Is the Alpine Fault convergent, divergent, or transform? EARLIER CONCERN OVER IMPACT ON ALPINE FAULT. Dive to the bottom of the Pacific Ocean to learn about the features of the Hikurangi Trench in 3D. [4] Bird considers them to be unconnected. [1] The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. The Alpine Fault runs right through the heart of New Zealand's glacier county on the country's south island. 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. You can pick out the line of the Alpine Fault on this satellite image of the South Island. Generally the fault has a simple straight trace, striking ca. The Alpine Fault, a transpressional plate boundary between the Australia-Pacific plates, is known to rupture periodically (200-400yr) with large magnitude earthquakes (Mw~8) and is currently nearing the end of its latest interseismic period. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges. The oldest part disappearing by way of the plate tectonics cycle is early-Cretaceous (145 to 137 million years ago). The Alpine Fault is sometimes compared with California's San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. The Alpine Fault is called a strike slip or transform fault. It is widely recognised that the pioneering work of Harold Wellman, a surveyor, geologist, gold miner and intrepid explorer, revealed the large plate boundary fault in the South Island of New Zealand – the Alpine Fault.
