A smaller number of transform faults cut continental lithosphere. San Andreas Fault in California and Alpine Fault of New Zealand. A smaller number of transform faults cut continental lithosphere. Spot the fault. OTHER SETS BY THIS CREATOR. Transform plate boundary faults accommodate high rates of strain and are capable of producing large (Mw>7.0) to great (Mw>8.0) earthquakes that pose significant seismic hazard. Plates are not being added to a plate or broken from transform plate boundary. Topic 2 Lesson 2 … There is dextral strike-slip motion as well as convergence between the Australian and Pacific plates. en The continent of Zealandia, which separated from Australia 85 million years ago and stretches from New Caledonia in the north to New Zealand’s subantarctic islands in the south, is now being torn apart along the transform boundary marked by the Alpine Fault. Januar 2016 (englisch). When stress releases, earthquakes happen from transform plate boundaries. It runs as a single structure for over 500 km. Because of the thickness of the continental lithosphere and its variety of rocks, transform boundaries on continents are not simple cracks but wide zones of deformation. The western ramparts of New Zealand’s Southern Alps define a remarkable straight line visible from space – the trace of the Alpine Fault. The forces affecting them include a degree of compression or extension across them, creating dynamics known as transpression and transtension. The alpine fault runs along the west side of the South Island of New Zealand and is "one of the longest, straightest, and fastest-moving plate boundary transform faults on Earth."(eg. Although they neither create nor destroy land, transform boundaries and strike-slip faults can create deep, shallow earthquakes. miles. The result is a split in the crust, called a fracture zone, that extends across the seafloor far beyond the small transform that created it. Transforms are strike-slip faults. More exactly, the Alpine Fault. A rupture along the full length of the fast-slipping Alpine Fault on New Zealand’s South Island poses the largest potential seismic threat to the southern and central parts of the country. The Alpine Fault • Running about 600km up the spine of the South Island, the Alpine Fault is the on-land boundary of the Pacific and Australian tectonic plates. The average slip rates in the fault's central region are abo… The western ramparts of New Zealand’s Southern Alps define a remarkable straight line visible from space – the trace of the Alpine Fault. The faults within this system head southwards and converge to form the Alpine Fault, which carries most of the plate boundary strain in the region. I am at the south island of New Zealand! It is the longest active fault in New Zealand. The Alpine Fault is a transform boundary between the Pacific Plate and the Indo-Australian Plate. The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. Two models have been proposed to explain the Alpine Fault-Puysegur subduction transition along the Fiordland Margin. A rupture along the full length of the fast-slipping Alpine Fault on New Zealand’s South Island poses the largest potential seismic threat to the southern and central parts of the country. Faults and Earthquakes. The Alpine Fault in New Zealand is one of the longest, straightest and fastest slipping plate boundary transform faults on Earth and produces earthquakes at quasi-periodic intervals. GirlyStitch GirlyStitch Answer: B. SECTION II: The Plate Boundary (Alpine Fault) & Associated Mountain Building (Southern Alps) The Alpine Fault, New Zealand: Surface Geology and Field Relationships 159 Richard J. Norris and Alan F. Cooper . Map of Tectonic Plates and Their Boundaries, Reverse, Strike-Slip, Oblique, and Normal Faults, Introduction to Convergent Plate Boundaries, Learn About the History and Principles of Plate Tectonics, 5 Different Ways of Classifying Volcanoes. Another example of a transform boundary on land is the Alpine Fault of New Zealand. 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. Transform Boundary – Alpine Fault, South Island, New Zealand. Initially skeptical of plate tectonics, Tuzo Wilson was also the first to propose the theory of hotspot volcanoes. The Alpine Fault is responsible for forming the Southern Alps mountain range, which has been pushed up on the Pacific Plate side of the boundary. However, most of the motion on the fault is strike-slip (side to side), with the Tasman district and West Coast moving North and Canterbury and Otagomoving South. Alpine Fault – Tectonic setting of New Zealand: astride a plate boundary which includes the Alpine Fault. The Livingstone Fault marks the boundary between red and grey rocks in the Olivine Wilderness Area. of the Alpine Fault in South Island, New Zealand, where the transform Alpine Fault connects oblique subduction zones of opposite polarities (Figure 1). New Zealand is situated at the edge of both the Australian and Pacific tectonic plates. Add your answer and earn points. The _____ and the Alpine Fault of New Zealand are examples of transform plate boundaries. transform boundary between the Pacific and Australian plates. Transform boundaries also form on larger scales on land like the San Andreas fault in Western North America and the Alpine fault in New Zealand. OTHER SETS BY THIS CREATOR. What are the Different Kinds? 18 terms. A smaller number connect mid-ocean ridges and subduction zones. Onshore it extends 650 kilometres from Blenheim to Milford Sound. There are three types of plate boundaries or zones, each of which features a different type of plate interaction. https://tectonics-etc.blogspot.com/2011/04/alpine-fault.html Contributor: Hobart KingPublisher, Geology.com. Transform boundaries connect to perpendicular divergent (and sometimes convergent) boundaries on both ends, giving the overall appearance of zig-zags or staircases. Alpine Fault: The Alpine Fault is a transform fault running across New Zealand's South Island. There is no vertical movement—only horizontal. The Alpine Fault that runs for over 500 km along the west coast of the South Island is a transform boundary between the plates, where compressional movement is causing the Southern Alps to be uplifted at a rate of approximately 7 mm/year New Madrid Fault of Arkansas B. Choctaw Fault of Oklahoma C. San Andreas Fault of California D. East African Rift E. Rio Grande Rift. Red Africa Sea and The Red Sea. How they meet each other changes along the boundary. The others are convergent boundaries (where plates collide) and divergent boundaries (where plates split apart). These two subduction areas are joined together by the Alpine Fault. The San Andreas connects a divergent boundary in the Gulf of California with the Cascadia subduction zone. Both the San Andreas Fault and the Alpine Fault are shown on our Interactive Plate Tectonics Map. The Alpine Fault that runs for over 500 km along the west coast of the South Island is a transform boundary between the plates, where compressional movement is causing the Southern Alps to be uplifted at a rate of approximately 7 mm/year OTHER SETS BY THIS CREATOR. University of Otago – Geology Department, abgerufen am 21. As the plates in this space continue to diverge, they do so in opposite directions. The fracture zone that forms a transform plate boundary is known as a transform fault. The fracture zone that forms a transform plate boundary is known as a transform fault. Transform boundaries also form on larger scales on land like the San Andreas fault in Western North America and the Alpine fault in New Zealand.
