The Alpine Fault is a geological fault, known as a right-lateral strike-slip fault, that runs almost the entire length of New Zealand's South Island. In this press release from New Zealand’s Science Media Centre, Professor Euan Smith of Victoria University in Wellington has done a great job of describing the quake (he thinks that we’re looking at sequential ruptures of the same fault) and the seismic hazard going forward. Lesson 3 Gas Behavior. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.. A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal. The rupture will produce one of the biggest earthquakes since European settlement of New Zealand, and it will have a major impact on the lives of many people. The fault mover 30mm a year! These are common at mid-ocean ridges, but they do not normally produce deadly tsunamis because there is no vertical displacement of seafloor. Transform boundaries connect to perpendicular divergent (and sometimes convergent) boundaries on both ends, giving the overall appearance of zig-zags or staircases. 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. New Zealand is situated at the edge of both the Australian and Pacific tectonic plates. miles. It begins in Christchurch at 9 am with a sit­uation report on the hours since 3 am: Power outage across the entire South Island was almost instant. 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 most famous example of this is the San Andreas Fault Zone of western North America. divergent examples. Contributor: Hobart KingPublisher, Geology.com. Like all plate boundaries, the movement of crust along transform and strike-slip faults creates earthquakes. The _____ and the Alpine Fault of New Zealand are examples of transform plate boundaries. Field area accessed by boat 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. A. As our only present-day indicator of active deforma-tion on the Alpine Fault, tremor provides a unique means of documenting and elucidating ambient coupling and stress conditions along this portion the plate boundary… 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. Examples of features at transform boundary. An example of another transform boundary is the Alpine fault of New Zealand that is on land. Some even connect mid-ocean ridges and subduction zones. 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. B. San Andreas Fault C. Mid-Atlantic Ridge D. Himalayas 1 See answer tambiaoangelo21 is waiting for your help. The Livingstone Fault marks the boundary between red and grey rocks in the Olivine Wilderness Area. Alpine Fault Tours began in 2012 when Gray and Vickie Eatwell bought a farm next to the natural exposure of the Alpine Fault, at Gaunt Creek, near Whataroa in South Westland, New Zealand. 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. 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. Some even connect mid-ocean ridges and subduction zones. 25 terms. of the Alpine Fault in South Island, New Zealand, where the transform Alpine Fault connects oblique subduction zones of opposite polarities (Figure 1). The fracture zone that forms a transform plate boundary is known as a transform fault. This lateral movement forms active transform boundaries. o Thermal Structure and the “Cold Wall.” o Ridge Offset and Spreading Rate Continental transform faults o Examples of Continental Transform Faults San Andreas–Gulf of California Transform System Dead Sea Transform System. Continental transforms are more complex than their short oceanic counterparts. Transform boundaries are one example. There are three types of plate boundaries or zones, each of which features a different type of plate interaction. New Madrid Fault of Arkansas B. Choctaw Fault of Oklahoma C. San Andreas Fault of California D. East African Rift E. Rio Grande Rift. Berryman et al., 2012). It is the longest active fault in New Zealand. Alpine Fault: The Alpine Fault is a transform fault running across New Zealand's South Island. OTHER SETS BY THIS CREATOR. A smaller number connect mid-ocean ridges and subduction zones. These extra forces are why coastal California, basically a transform tectonic regime, also has many mountainous welts and down-dropped valleys. Plates are not being added to a plate or broken from transform plate boundary. 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 Flickr Creative Commons Images. Topic 2 Lesson 2 … 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. divergent examples. No. Faults and Earthquakes. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. San Andreas Fault in California and Alpine Fault of New Zealand. 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. The western ramparts of New Zealand’s Southern Alps define a remarkable straight line visible from space – the trace of the Alpine Fault. The Alpine Fault is a geological fault, known as a right-lateral strike-slip fault, that runs almost the entire length of New Zealand's South Island. 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. Alpine Fault Tours began in 2012 when Gray and Vickie Eatwell bought a farm next to the natural exposure of the Alpine Fault, at Gaunt Creek, near Whataroa in South Westland, New Zealand. 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. Alpine Fault – Tectonic setting of New Zealand: astride a plate boundary which includes the Alpine Fault. New Zealand is situated at the edge of both the Australian and Pacific tectonic plates. This configuration offsets energy from the whole process. Add your answer and earn points. Fleurdelys_Strongoli. Flickr Creative Commons Images. There is dextral strike-slip motion as well as convergence between the Australian and Pacific plates. Transform def. Their relative movement can be described as either dextral (to the right) or sinistral (to the left). 18 terms. What are the Different Kinds? Transform examples. The Alpine Fault is called a strike slip or transform fault. In between earthquakes, the Alpine Fault is locked. Geologic Faults What Is It? Initially skeptical of plate tectonics, Tuzo Wilson was also the first to propose the theory of hotspot volcanoes. The geology of New Zealand makes that an incredibly complex question to answer - but a new study evaluating millions of different earthquake scenarios will give us a much better idea. Does subduction happen along the whole plate boundary in New Zealand? Although they neither create nor destroy land, transform boundaries and strike-slip faults can create deep, shallow earthquakes. When these earthquakes occur on land, on the other hand, they can cause large amounts of damage. Another example of a transform boundary on land is the Alpine Fault of New Zealand. New Zealand geologists have been doing a sterling job of getting good information out to the public. 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. The average slip rates in the fault's central region are abo… 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. Transform Plate Boundary features. One major geographic feature of the South Island of New Zealand is the Southern Alps, a mountain range caused by tectonic uplift along the Alpine Fault. Two models have been proposed to explain the Alpine Fault-Puysegur subduction transition along the Fiordland Margin. Fleurdelys_Strongoli. 20 years earlier, they had been in tourism in Fiordland NZ, taking international visitors on overnight cruises to see the fiords - and this will become relevant in a moment. The alpine fault is located in New Zeland. miles space. 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 Home » Teaching Plate Tectonics » Transform Boundaries. Transform Plate Boundaries are locations where two plates slide past one another. An example of another transform boundary is the Alpine fault of New Zealand that is on land. Some … Each of these three types of plate boundary has its own particular type of fault (or crack) along which motion occurs. There have been no major earthquakes on the main portion of it. 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. When you look at the transform fault diagram, imagine the double line as a divergent plate boundary and visualize which way the diverging plates would be moving. New evidence of a 19th century earthquake on New Zealand's Alpine fault suggests that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events. Red Africa Sea and The Red Sea. OTHER SETS BY THIS CREATOR. the Alpine Fault-Hikurangi Trough, northeast New Zealand, shows a progressive transform-subduction transition that is accommodated by motion partitioning between the subduction • Now at Universit6 des Antilles et de la Guyane, Dpt de G6ologie, Pointe h Pitre, Guadeloupe 2 Now at National Institute of Water and Atmospheric Research, It runs as a single structure for over 500 km. Explanation: The San Andreas connects a divergent boundary in the Gulf of California with the Cascadia subduction zone. Spot the fault. The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges. Convergent boundaries are thrust or reverse faults, and divergent boundaries are normal faults. The Alpine Fault is sometimes compared with California’s San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. 1 Introduction. The most famous example of this is the San Andreas Fault Zone of western North America. The others are convergent boundaries (where plates collide) and divergent boundaries (where plates split apart). Answer: B. The Alpine Fault. 22 terms. The San Andreas fault itself is just one thread in a 100-kilometer skein of faults making up the San Andreas fault zone.
