after a severe earthquake on the Alpine Fault. The worst-affected areas if the Alpine Fault were to rupture have been revealed. Geologists and authorities are racing to quantify what might happen, and how they might respond in the event of the next one, likely to occur some time in the next 50 years. The Alpine Fault is a transform fault running across New Zealand's South Island. In comparison, the Greendale fault that broke in the first, September earthquake in Christchurch had a probability over a hundred times lower (and produced a much smaller earthquake)” It came from Reuters and even though I cannot tell who the writer was, it is not about the writer. Transform faults are also referred to as "conservative" plate boundaries, inasmuch as … The Alpine Fault is a geological fault that runs entirely through New Zealand's South Island.It forms a boundary between the Pacific Plate and the Indo-Australian Plate. The Alpine Fault runs for over 800km up the spine of the South Island. It's also important to note that the Alpine Fault is not the only fault in the country capable of a 7.6 or larger. The Alpine fault is perhaps only the fifth such long record and it has revealed the most regular rupture behaviour yet reported. The council's emergency management team has been working with Selwyn communities to get ready. The Alpine Fault principal slip zone (PSZ) is frictionally weaker than wall rock at depths shallower than 3 km. The Alpine Fault is a boundary where two of the dozen or so enormous tectonic plates which make up the surface of the globe collide. The Pacific Plate on the easterly area of New Zealand is moving westwards and the Australian Plate, on the western side of New Zealand moves eastwards. About Alpine Fault Tours Guided educational tours to the natural exposure of the Alpine fault, at Gaunt Creek, near Whataroa, South Westland. Tours are 2.5 hours, and require walking. The Alpine Fault • Running about 600km up the spine of the South Island, the Alpine Fault is the boundary of the Pacific and Australian tectonic plates. Preparing for an Alpine Fault earthquake. I stumbled upon news a mere two hours old, now this is nothing special, but the content was. What is the take-home message from this investigation? The Alpine Fault. A reinterpretation of structural and paleomagnetic data suggests that New Zealand's Alpine Fault accommodates a far greater percentage of geologically recent plate motion than previously thought. Continental transform faults are dominantly highly localized strike-slip shear zones hundreds of kilometers long that accumulate tens to hundreds of kilometers of displacement. The Alpine Fault runs almost the entire length of the South Island, and an earthquake there will be felt by much of the country. The fault line is where the Eurasian and … Earthquakes along the fault have formed the Southern Alps So no fault in … The Alpine Fault The Alpine Fault, marked here by the yellow line, stretches nearly the entire length of Te Waipounamu, the South Island of Aotearoa New Zealand. The Alpine Fault is sometimes compared with California’s San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. 18:35 You become what you are. Movement along this fault has uplifted the Southern Alps and helped shape the South Island landscape we know today. The Alpine Fault connects two "subduction" margins where the ocean floor descends into the Earth's mantle. 4. It’s the part of the active boundary between the Pacific and Australian tectonic plates where they intersect on land. Alpine Fault are the geologists who went out there and found out about it. Fault ruptures (earthquakes) have displaced river terraces that cross the fault. The Alpine Fault is a fault located in the South Island of New Zealand running through the middle for about 600 kilometers. The Alpine Fault is a geological fault, more specifically known as 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 PSZ and wall rock exhibit velocity-weakening and unstable behavior at temperatures ≥180 °C. At 3 AM on May 29, 2013, the South Island’s technological uncon­scious roars […] An Alpine Fault earthquake will likely rupture a larger fault length (several hundreds of kilometres rather than several tens of kilometres) over a longer period of time (100s of seconds rather than tens of seconds) and affect a much larger area than the Darfield earthquake. The Alpine Fault is one of the world's major plate boundaries and New Zealand's most hazardous earthquake-generating fault. A fault zone is a cluster of parallel faults. Ten million years ago the two plates did not so much collide as brush past each other. There is also the subduction zone off the North Island's East Coast, the Wellington faults are typically thought to be that strong and more. PHOTO: PROJECTAF8.CO.NZ An historical account about the Alpine Fault is a worthy study in itself as it goes hand in hand with the development of the theory of modern plate tectonics and all the technological leaps and “The Alpine Fault has the highest level of probability for rupture of any fault in New Zealand. The Alpine Fault Trace runs from lower left towards the hill, J.Thomson / GNS.Science The northern section of the Alpine Fault runs through this area. It comes after scientists claimed the Alpine Fault is overdue for an earthquake that could reshape the South Island. 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. An earthquake on the Alpine Fault is likely to be one of the most significant disasters that could affect Selwyn district. Fault line... A graphic shows an indicative line of the Alpine Fault in relation to Wanaka and Queenstown. A wall has been built across the fault scarp to check for movement. The South Island Alpine Fault Earthquake Response (SAFER) Framework provides a concept of coordination of response and priority setting across all six South Island Civil Defence Emergency Management … planning and preparing a coordinated response across the South Island. The Alpine Fault runs right through the heart of New Zealand's glacier county on the country's south island. • Our data suggest that earthquakes are most likely to nucleate at depths between 1.8 and 8.8 km along the Alpine Fault zone. The Alpine fault is a transform fault at the boundary of the Indo-Australian and Pacific Plates. At this point the surfaces of the two plates making up the South Islands alpine fault meet. The horizontal movement of this fault is about 30 meters per 100 years, which by global standards is very fast! Movement along this fault has uplifted the Southern Alps and produced large earthquakes. It is a dominant feature of the South Island. "One of the issues that makes the Alpine fault interesting is that while it is a strike slip fault for most of its length, it begins in a The Alpine Fault is where two great tectonic plates (the Pacific and Australian) plates collide. However, ... or, less common, within continental lithosphere, such as the Dead Sea Transform in the Middle East or the Alpine Fault in New Zealand. The Alpine Fault runs for about 600km along the west of the Southern Alps. AF8 [Alpine Fault magnitude 8] is a collaborative effort to save lives by. The Alpine Fault is the boundary between the Pacific crustal plate and the Australian plate. The Alpine Fault ruptures—on average—every 330 years with a magnitude 8 earthquake. Ents, orcs and hobbits may have trod upon New Zealand soils, but beneath the southern island lies a giant earthquake fault that may help seismologists understand how the Earth moves and bends, according to a Penn State seismologist. From work on the Alpine Fault, we pose the questions: what is the deep structure of a continental transform, and how does the displacement become localized? "By comparison, the Kaikōura Earthquake in 2016 ruptured a total fault length of 200km in … The red line on this map shows our plate boundary (see Module 2). The next Alpine Fault earthquake would likely also be a long-duration event – unzipping the crust for as much as three minutes - because of the sheer length of the fault.
