Figure 1 Active fault map (black & grey lines) of South Island highlighting the Alpine Fault (bold within West Coast region). 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 uncertainty is an estimate of how well-mapped or located the fault is at any given point, based on the type of data that Here he explains what they were up to and shares some photos of the damage. About Alpine Fault Tours Guided educational tours to the natural exposure of the Alpine fault, at Gaunt Creek, near Whataroa, South Westland. The Alpine Fault is sometimes compared with California's San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. New Zealand’s Alpine Fault is a seismically active, “crust-busting” plate boundary fault. A fault with 300 meters of both, on the other hand, would. 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. 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. [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. The Deep Fault Drilling Project (DFDP) is an international science project studying the Alpine Fault in western South Island. Faults taken from New Zealand Active Faults Database Earth & Space Science What tectonic setting is most likely associated with the Alpine fault? This type of fault zone is generated in the upper 5 to 10 kilometres of the … Berryman et al., 2012). Alpine Fault. Cochran said data from the two sites gave evidence for 26 Alpine Fault earthquakes in the past 8000 years. The type of plate boundary at the Alpine Fault is a transform boundary. There is dextral strike-slip motion as well as convergence between the Australian and Pacific plates. What type of stress are the rocks at the fault under? Base is a screenshot from NASAWorldWind, from the free Blue Marble image courtesy of NASA Earth Observatory. 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. 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. New research has revealed that some of the West Coast is sandwiched between enormous offshore fault lines and the Alpine Fault. Describe how rock bodies are moving at the fault plane. 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 … Figure 10 Fault Location in terms of uncertainty for the Alpine Fault. The rock contains bands of melted rock that seeps into fractures. Fault names and detailed mapping localities are shown in the legend. It is located at the Tibetan Plateau. Jack was part of a team of experts that went into the field immediately following the Kaikoura earthquake to map the surface ruptures. 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. In New Zealand they are formed along the Alpine fault by earthquakes. https://www.sciencephoto.com/media/112125/view/alpine-fault-line 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. At a transform boundary, two tectonic plates slide past each other. The Marlborough cluster of fault lines are connected to the South Island's main fault, the Alpine Fault. The seismicity rate of the Alpine fault is low but comparable to locked sections of the San Andreas fault, with large earthquakes expected. J ack Williams is a PhD Student at the University of Otago, New Zealand, where he is studying the Alpine Fault. 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 a transform fault at the boundary of the Indo-Australian and Pacific Plates. Alpine Fault By Yanice Melendez D.L. Each type is the outcome of different forces pushing or pulling on the crust, causing rocks to slide up, down or past each other. Faults are elongated, complex zones of deformation, ranging from decimetres to kilometres in magnitude. Tours are 2.5 hours, and require walking. 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 is a mature, dextral strike-slip fault that marks the western boundary of the Southern Alps. It is the on-land boundary of the Pacific and Australian plates.But where exactly is it? 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. In New Zealand they are formed along the Alpine fault by earthquakes. 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. Inset: Plate tectonic setting of New Zealand, including the locations of subduction margins It's important to know a fault's type -- it reflects the kind of tectonic forces that are acting on a specific area. Stress levels on the Alpine fault. The Alpine Fault runs 400km up the South Island, along the western edge of the Southern Alps. Alpine Fault Tours: The earth moves - See 26 traveler reviews, 47 candid photos, and great deals for Whataroa, New Zealand, at Tripadvisor. The lack of a historical record for the Alpine Fault means that we must instead examine the geological record left by past ruptures. == Philippine Mobile Belt == The Philippine Mobile Belt is composed of a large number of accretionary blocks and terranes. That gave an average time between earthquakes of 300 years. Because many faults show a combination of dip-slip and strike-slip motion, geologists use more sophisticated measurements to analyze their specifics. 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. The Marlborough Fault System is a major sequence of faults in the upper South Island. 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. If you want to do something different and have a passing interest in geology, then this is a ‘must do’ tour. 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. It fills a knowledge gap for the international science community trying to understand earthquake processes. In the plot above the area of the circles correlates with the area percentage of … The Alpine Fault is one of the world’s major geological features. The rock contains bands of melted rock that seeps into fractures. I’ve analyzed quartz grain size data from ~250 rocks spanning 170 km of the fault. 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. Several major faults run alongside and within this system, including the Wellington Fault. Where will the next earthquake centred on the Alpine Fault begin? 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. What type of fault is this? [1] The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. Major populated areas near your fault The Alpine fault is defined as the 650 km long feature that extends the length of the South Island.
