alpine fault what plate boundary

[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. 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. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. It runs as a single structure for over 500 km. At a transform boundary, two tectonic plates slide past each other. [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. Dive to the bottom of the Pacific Ocean to learn about the features of the Hikurangi Trench in 3D. The oldest part disappearing by way of the plate tectonics cycle is early-Cretaceous (145 to 137 million years ago). It forms the sharp line separating the snow-covered Southern Alps in the east from the low coastal plain bordering the Tasman Sea in the west. 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. With the development of plate tectonics in the 1970s, the Alpine Fault was recognised as part of the boundary between Pacific and Australian plates. Find out how it was discovered and learn what science can tell us about Alpine Fault earthquakes. Module 3: Unlocking the Hikurangi subduction zone. Find out how it was discovered and learn what science can tell us about Alpine Fault earthquakes. 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. 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 Pacific Plate is almost entirely oceanic crust, but it contains some continental crust in New Zealand, Baja California, and coastal California. 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 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 Alpine fault is the Pacific-Australian plate boundary in the South Island of New Zealand. It runs as a single structure for over 500 km. What’s On Our Plates? The next level of complexity in explanation addresses the transpressive nature of the Alpine Fault, and the consequent development and continued growth of the Southern Alps. [2], The Pacific Plate contains an interior hot spot forming the Hawaiian Islands. 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. Langridge said researchers in California and New Zealand have a long history of earthquake science collaboration and are learning from each other about the treatment of active faults and fault segmentation for seismic hazard models. Spot the fault. Nabelek, John L. Abstract. The Alpine Fault is one of the world's major plate boundaries and New Zealand's most hazardous earthquake-generating fault. The fracture zone that forms a transform plate boundary is known as a transform 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. Generally the fault has a simple straight trace, striking ca. 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. , each time producing an earthquake of about magnitude 8 Australian Plates the Antarctic plate the.
