The Alpine Fault quickly became accepted as a notable feature of the geology of New Zealand, and by 1948 was included on standard geological maps. Base is a screenshot from NASAWorldWind, from the free Blue Marble image courtesy of NASA Earth Observatory. The rock contains bands of melted rock that seeps into fractures. == Philippine Mobile Belt == The Philippine Mobile Belt is composed of a large number of accretionary blocks and terranes. Earth & Space Science What tectonic setting is most likely associated with the Alpine fault? Here he explains what they were up to and shares some photos of the damage. The Marlborough cluster of fault lines are connected to the South Island's main fault, the Alpine Fault. Elisabeth, your guide, has a good knowledge of the Alpine Fault, and to be able to straddle 2 tectonic plates was a real moment to remember. It is located at the Tibetan Plateau. Each type is the outcome of different forces pushing or pulling on the crust, causing rocks to slide up, down or past each other. The Altyn Tagh fault is at least 1200 km long and is an active fault line that has been estimated to have been moving since the age of dinosaurs. That gave an average time between earthquakes of 300 years. Inset: Plate tectonic setting of New Zealand, including the locations of subduction margins 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. The lack of a historical record for the Alpine Fault means that we must instead examine the geological record left by past ruptures. A fault with 300 meters of both, on the other hand, would. The rock contains bands of melted rock that seeps into fractures. Faults are elongated, complex zones of deformation, ranging from decimetres to kilometres in magnitude. Fault names and detailed mapping localities are shown in the legend. 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. https://www.sciencephoto.com/media/112125/view/alpine-fault-line What type of fault is this? 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. 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. 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. It fills a knowledge gap for the international science community trying to understand earthquake processes. Cochran said data from the two sites gave evidence for 26 Alpine Fault earthquakes in the past 8000 years. Alpine Fault Tours: The earth moves - See 26 traveler reviews, 47 candid photos, and great deals for Whataroa, New Zealand, at Tripadvisor. Alpine Fault By Yanice Melendez D.L. [1] The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. The uncertainty is an estimate of how well-mapped or located the fault is at any given point, based on the type of data that J ack Williams is a PhD Student at the University of Otago, New Zealand, where he is studying the Alpine Fault. What type of stress are the rocks at the fault under? Jack was part of a team of experts that went into the field immediately following the Kaikoura earthquake to map the surface ruptures. Seismicity decreases north of Bruce Bay at the Alpine fault and within a triangular region along the Alpine fault located between the Hope and Porters Pass fault zones. Geologists working on Project AF8 believe that the next severe earthquake on the Alpine Fault is most likely to be a rupture that begins in South Westland and “unzips” northwards and will … Faults taken from New Zealand Active Faults Database Berryman et al., 2012). One indication that things have not always been quite so calm on the Alpine fault is the presence of a rock type called psuedotachylite, which is thought to form either during an earthquake or with a meteor impact. The Alpine Fault is sometimes compared with California's San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. This type of fault zone is generated in the upper 5 to 10 kilometres of the … Several major faults run alongside and within this system, including the Wellington Fault. Piqiang Fault O Reverse Left lateral O Normal O Right lateral Their fault, not mine An anticline is best described as: An arching fold of rock caused by tension (pulling) O A U-shaped fold of rock caused by tension (pulling) An arching fold of rock caused by compression (pushing) O A U-shaped fold of rock caused by compression (pushing) The sister of Patsy's mom. For engineering projects the so-called brittle fault deserves our particular attention. Figure 1 Active fault map (black & grey lines) of South Island highlighting the Alpine Fault (bold within West Coast region). In New Zealand they are formed along the Alpine fault by earthquakes. There is dextral strike-slip motion as well as convergence between the Australian and Pacific plates. About Alpine Fault Tours Guided educational tours to the natural exposure of the Alpine fault, at Gaunt Creek, near Whataroa, South Westland. It has ruptured four times in the last 900 years, resulting in earthquakes of around magnitude 8, and is now considered highly probable to go again in the next 50 years. The Alpine fault is defined as the 650 km long feature that extends the length of the South Island. [Chapter Break] After their ground­breaking paper on the Alpine Fault, Willett was posted to Invercargill and Wellman to another war­time project at d’Urville Island. Stress levels on the Alpine fault. Because many faults show a combination of dip-slip and strike-slip motion, geologists use more sophisticated measurements to analyze their specifics. The Alpine Fault runs 400km up the South Island, along the western edge of the Southern Alps. New Zealand’s Alpine Fault is a seismically active, “crust-busting” plate boundary fault. New research has revealed that some of the West Coast is sandwiched between enormous offshore fault lines and the Alpine Fault. If you want to do something different and have a passing interest in geology, then this is a ‘must do’ tour. The Alpine Fault is one of the world’s major geological features. The seismicity rate of the Alpine fault is low but comparable to locked sections of the San Andreas fault, with large earthquakes expected. It's important to know a fault's type -- it reflects the kind of tectonic forces that are acting on a specific area. The Deep Fault Drilling Project (DFDP) is an international science project studying the Alpine Fault in western South Island. Tours are 2.5 hours, and require walking. In the plot above the area of the circles correlates with the area percentage of … In New Zealand they are formed along the Alpine fault by earthquakes. Where will the next earthquake centred on the Alpine Fault begin? Major populated areas near your fault One indication that things have not always been quite so calm on the Alpine fault is the presence of a rock type called psuedotachylite, which is thought to form either during an earthquake or with a meteor impact. The type of plate boundary at the Alpine Fault is a transform boundary. The Alpine Fault is a mature, dextral strike-slip fault that marks the western boundary of the Southern Alps. Figure 10 Fault Location in terms of uncertainty for the Alpine Fault. I’ve analyzed quartz grain size data from ~250 rocks spanning 170 km of the fault. The Alpine fault is a transform fault at the boundary of the Indo-Australian and Pacific Plates. St. Andreas Transform Fault Alpine Fault New Zealand The types of transform fault that are always the longest Oceanic Transform Fault Continental Transform Fault EXPLORING THE PLANETS 3 The crust type and general of thickness of the crust. Alpine Fault. At a transform boundary, two tectonic plates slide past each other. English: Map of the Marlborough Fault System, the set of dextral strike-slip faults that accommodates the switch from the Alpine Fault to the Kermadec Trench along the plate boundary through New Zealand. The Philippine Fault System is a major inter-related system of faults throughout the whole of the Philippine Archipelago, primarily caused by tectonic forces compressing the Philippines into what geophysicists call the Philippine Mobile Belt.
