[22], Richard Norris and Alan Cooper from the Department of Geology, University of Otago conducted extensive research on the structure and petrology of the Alpine Fault respectively throughout the later 20th and early 21st centuries. How to solve: What type of fault is the Alpine Fault? Holes were drilled for explosives, and when the explosives were set off, a multi-channel seismograph recorded the seismic waves. Harold William Wellman was an English-born New Zealand geologist known for his work on plate tectonics. [1] This, along with isostatic constraints, has kept the Southern Alps less than 4000 m. Uplift on the Alpine Fault has led to the exposure of deep metamorphic rocks near the fault within the Southern Alps. The surface rupture has extended into the north section of the fault as far as the Haupiri River area, which is 25 km northeast of the Alpine Fault junction with the Hope Fault. There have been no major historical earthquakes on the Alpine Fault. Science and technology. The Clarence Fault is an active dextral strike-slip fault in the northeastern part of South Island, New Zealand. The uplift is due to an element of convergence between the plates, meaning that the fault has a significant high-angle reverse oblique component[ clarification needed ] to its displacement. That's before satellite photographs or plate tectonics. See this Interactive map of the Alpine Fault and links to a virtual field trip on the University of Otago Geology website. Beban GNS Science Consultancy Report 2011/217 September 2011 . The Alpine Fault runs for about 600km up the spine of the South Island, and is one of the world’s major geological features. [6] [7] Also near the surface the fault can have multiple rupture zones. She then worked as a research associate professor in geology and associate dean (international) in the Division of Sciences at the University of Otago. Scientists say that a similar earthquake could happen at any time as the interval since 1717 is longer than between the earlier events. faille alpine (Nouvelle-Zélande, île du Sud) : l'activité de cette faille est sujette à de nombreuses études (Deep Fault Project [1]), car elle est très dangereuse. The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. [2], The fault zone is exposed at numerous locations along the West Coast and typically comprises a 10-50 m wide fault gouge zone with pervasive hydrothermal alteration. It was centred at a depth of 7 km (4.3 mi), about 5 km (3 mi) south-east of Christchurch, which had previously been devastated by a magnitude 6.2 MW earthquake in February 2011. How often does the Alpine Fault rupture? The Alpine Fault then runs the length of the South Island just west of the Southern Alps to near Lewis Pass in the central northern section of the island. The Alpine Fault forms a "transform" boundary between the Pacific Plate and Indo-Australian Plate. [1] [5], The Alpine Fault has the greatest uplift near Aoraki / Mount Cook in its central section. Wellman became a Fellow of the Royal Society of New Zealand in 1954, and was awarded the Hector Memorial Medal and Prize in 1957 and the McKay Hammer Award in 1959. What information is revealed? These large earthquakes don’t happen very often – the last one was nearly 300 years ago. of the Alpine Fault R.M. The horizontal movement along the fault is not smooth, as both sides are locked together. Curious Minds is a Government initiative jointly led by the Ministry of Business, Innovation and Employment, the Ministry of Education and the Office of the Prime Minister’s Chief Science Advisor. In the middle the Alpine Fault is a transform boundary and has both dextral (right-lateral) strike-slip movement and uplift on the southeastern side. Researchers are studying the Alpine Fault to investigate past earthquakes, mountain formation and the structure of the Earth’s crust. In New Zealand they are formed along the Alpine fault by earthquakes. It forms part of the North Island Fault System, which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian Plate and Pacific Plate. using ground penetrating radar to observe hidden evidence of uplift and horizontal movement. [10] So while earthquakes are an important part of Māori oral tradition, no stories have been passed down about South Island earthquakes. Famous examples of these include the San Andreas Fault of California, the Alpine Fault of New Zealand's south island, and the Anatolian Fault in Turkey Alpine Fault. Snow on the mountains of the Pacific plate contrasts with the lower land of the Australian plate. This survey will open in a new tab and you can fill it out after your visit to the site. It forms part of the North Island Fault System, which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian Plate and Pacific Plate. Here the relative motion between the two plates averages 37–40 mm a year. 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. Between 25 and 12 million years ago the movement on the proto-Alpine Fault was exclusively strike-slip. Geologically, this is a high probability. Virginia currently works as a Professor at the University of Mainz. [27] The DFDP was the second project to try to drill an active fault zone and return samples after the San Andreas Fault Observatory at Depth. In earthquake terms, the 850 kilometres (530 mi) long fault is remarkably consistent, rupturing on average every 330 years, at intervals ranging from 140 years to 510 years. [1] The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. Alpine Fault quake expected NZASE article 2019 Scientists estimate a 30 percent likelihood in the next 50 years of a magnitude 8 or higher (M8+) earth- quake along 400km of the Alpine Fault, a strength about three times greater than the 7.8 Kaikoura quake in 2016. How will the next Alpine Fault earthquake compare to the M7.1 Darfield earthquake of 4 September 2010? [22] The fault was officially named the Alpine Fault in 1942 as an extension of a previously mapped structure. dating trees buried by landslides using radiocarbon dating and tree growth rings (dendrochronology). Well that moves us on to our 3rd boundary type! Le temps de l'apprécier. The Wairarapa Fault is an active seismic fault in the southern part of the North Island of New Zealand. Alpine climate, climate that is typical to higher altitudes; Alpine tundra, a type of natural region or biome; Alpine orogeny, in geology; Alpine Fault, a geological fault running nearly the entire length of New Zealand's South Island; Biology. 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. She is one of the leaders of the Deep Fault Drilling Project of New Zealand's Alpine Fault, and was a research scientist on the Japan Trench Fast Drilling Project. [24] Originally this regional increase in grade was inferred to be from frictional heating along the fault not uplift of deeper geological sequences. Tours are 2.5 hours, and require walking. The epicentre was approximately 35 kilometres (22 mi) west of Hanmer. Alpine d'occasion - s’il est impossible de dénicher une A 110 pour moins de 50 000 €, on peut s’offrir une A 310 ou une A 610 à partir de 20 000 €. Ultrasonic image logs acquired in the DFDP‐2B borehole yield the first continuous, subsurface description of the transition from schist to mylonite in the hangingwall of the Alpine Fault, New Zealand, to a depth of 818 m below surface. In Wellington, close to the epicenter, shaking lasted for at least 50 seconds. 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 Otago moving South. [ clarification needed ] Most of the movement along the fault occurs in this zone. [11] Over the last thousand years, there have been four major ruptures along the Alpine Fault causing earthquakes of about magnitude 8. Located at 43°53'44.58"S 169°31'28.09"E, it runs the entire length of New Zealand's South Island, thus along the western edge of the Southern Alps. This fault has ruptured four times in the past 900 years, each time producing an earthquake of about magnitude 8. Virginia Toy is a New Zealand geologist who studies fault zones and earthquakes in New Zealand, Japan and Ecuador. Faille nord-anatolienne. [23] Wellman also proposed in 1964 that the Alpine Fault was a Cenozoic structure, which was in conflict with the older Mesozoic age accepted at the time. Interactive map of the Alpine Fault and links to a virtual field trip, digging trenches to find buried evidence, such as landslides. The alpine fault is located in New Zeland. Some trees survive landslides, but the event is marked by unusual growth rings. This earthquake was associated with the largest observed movement on a strike-slip fault, maximum 18 metres (59 ft). [2]. The Marlborough Fault System is a set of four large dextral strike-slip faults and other related structures in the northern part of South Island, New Zealand, which transfer displacement between the mainly transform plate boundary of the Alpine fault and the mainly destructive boundary of the Kermadec Trench, and together form the boundary between the Australian and Pacific Plates. using GPS to study small movements of nearby minor faults, and to measure growth of the Alps, using seismic data to find out how the many minor earthquakes in the area are linked to minor faults and the main Alpine Fault. This is unlike the North Island boundary, where a subduction zone is under water off the east coast. This PDF provides a summary from the West Coast Reginal Council on Alpine Fault research past and present, including details of Mark Yetton’s methods. Type: Full-length Release date: November 11th, 2011 Catalog ID: N/A Label: Independent Format: CD Reviews: None yet Songs; Lineup; Reviews; Additional notes; 1. 25 Reviews 1 Q&A. You can pick out the line of the Alpine Fault on this satellite image of the South Island. It forms part of the Marlborough Fault System, which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian Plate and Pacific Plate, from the transform Alpine Fault to the Hikurangi Trench subduction zone. Hours Today: 9:30 AM - 6:00 PM . [1] [3], The Pacific Plate and Indo-Australian Plate boundary forms the Macquarie Fault Zone in the Puysegur Trench off the southwestern corner of the South Island and comes onshore as the Alpine Fault just north of Milford Sound. The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. Read more. The way the waves are reflected and transmitted tells much about the rocks and structures near the fault. Langridge J.G. It is a dextral strike-slip fault with a component of uplift to the northwest as expressed by the Rimutaka Range. It forms part of the Marlborough Fault System, which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian Plate and Pacific Plate, from the transform Alpine Fault to the Hikurangi Trench subduction zone. The Japan Trench Fast Drilling Project (JFAST) was a rapid-response scientific expedition that drilled oceanfloor boreholes through the fault-zone of the 2011 Tohoku earthquake. The work involves scientists from several disciplines working together, using different methods, such as: Using techniques like these, scientists such as Mark Yetton of the University of Canterbury have found out that major earthquakes happened on the central Alpine Fault in 1100, 1450, 1620 and 1717. The Southern Alps had not yet formed and most of New Zealand was covered in water. It is a dextral (right-lateral) strike-slip fault with variable amounts of vertical movement causing uplift to the northwest, as expressed by a series of ranges. The council's emergency management team has been working with Selwyn communities to get ready. Fault Lines: Facts About Cracks in the Earth. [13] Newer research carried out by the University of Otago and the Australian Nuclear Science and Technology Organisation revised the dates of the pre-1717 earthquakes to between 1535 and 1596 (instead of 1620), 1374 and 1405 (instead of 1430), and 1064 and 1120 (instead of 1100). The Alpine Fault intersects the west coast of the South Island of New Zealand about four miles north of Dale Point at the entrance to Milford Sound; moraine 011 the west of the fault has beeili faulted against Fiordlancl Gneiss' on the east, A well defined fault trace was followed from the air from the south side of [25], The Deep Fault Drilling Project (DFDP) was an attempt in 2014 to retrieve rock and fluid samples and make geophysical measurements inside the Alpine Fault zone at depth. New research from Victoria University of Wellington could prompt a shift in thinking about the South Island’s Alpine Fault. It has been suggested that the surface rupture formed by this event helped influence Charles Lyell to link earthquakes with rapid movement on faults. [27] It was led by New Zealand geologists Rupert Sutherland, John Townsend and Virginia Toy and involves an international team from New Zealand, Canada, France, Germany, Japan, the United Kingdom, and the United States. [1] The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. 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. Above the Storm 08:20 Show lyrics (loading lyrics...) 3. Alpine Fault. Depuis le mois de juin, Alpine a diligenté trois nouvelles campagnes de rappel afin de corriger un potentiel défaut de fabrication sur l'Alpine A110. We've known about the Alpine Fault for around 80 years. This news article from Stuff covers some research on the frequency of past earthquakes along the Alpine fault.
