“I still think the major worry in Otago and Southland is the Alpine Fault itself, and also from the sorts of smaller faults through the South Island.” – Stuff Six quakes rattle NZ: A flurry of six earthquakes have struck the country overnight, with the strongest, a magnitude 4.9 , hitting off Seddon. Project AF8 Steering Group chairman Angus McKay, from Emergency Management Southland, said some of New Zealand's best scientific minds had worked together to produce a credible scenario for what would happen with the next major earthquake on fault line. For their date discovery, Howarth and Langridge used new techniques of radiocarbon-dating to reanalyse organic material found in trenches on the section of the fault between the Toaroha River, about 20km southeast of Hokitika, and Springs Junction. Project Alpine Fault Magnitude 8 (AF8) released a series of videos on Wednesday, warning there's compelling geological evidence to show it produces a significant earthquake of magnitude eight or greater every 300 years on average. This news article from Stuff covers some research on the frequency of past earthquakes along the Alpine fault. The Alpine Fault ruptures—on average—every 330 years with a magnitude 8 earthquake. Ms Cooper lives near the Alpine Fault, which is likely to rupture within the lifetime of many New Zealanders. GNS Science earthquake geologist Robert Langridge has been studying why the Alpine Fault is so susceptible to earthquakes - it's since been discovered that it may be the world's fastest-moving known fault line. The bend – where the fault turns from its northeast-southwest orientation to run in a more north-south direction – was a "big unknown" in terms of how it interfered with ruptures. GNS senior earthquake scientist Dr Rob Langridge inspects the fault zone in the Inchbonnie trench across the Alpine Fault. "The next step is to plan in more detail for a coordinated response to those impacts and the extensive disruption they will cause. From the LEARNZ Alpine Fault online field trip at… "We have used that scenario to work with our partners to identify the foreseeable impacts on communities and critical infrastructure across the South Island," he said. The four videos … MICHAEL MANGA Neat stuff in the Field Alpine Fault, New Zealand, 2009 The Alpine Fault is a strike-slip fault that runs nearly the entire length of New Zealand's south island. (File photo). The "big bend" in the Alpine Fault between about Springs Junction and Lake Rotoroa, near St Arnaud. The Alpine Fault is the boundary between the Pacific crustal plate and the Australian plate. ProjectAF8 is a South Island-wide effort to co-ordinate planning and preparation for a severe earthquake on the fault. Project Alpine Fault Magnitude 8 (AF8) released a series of videos on Wednesday, warning there's compelling geological evidence to show it produces a significant earthquake of … Just-released videos have shown what would happen in the event of a major quake along the South Island's big-risk Alpine Fault. Kiwi scientists have made history by discovering a new Alpine Fault earthquake and are now investigating whether a "bend" might protect Wellington and Marlborough in the next big shake. [Chapter Break] After their ground breaking paper on the Alpine Fault, Willett EPL Ltd owner Tom Thomson talks about the challenges he faced after the February 2011 earthquakes in Christchurch. The last rupture was believed to have happened in 1717. "Bends like that usually stop earthquakes.". GNS Science earthquake geologists studying layers in the trench across the Alpine Fault at Calf Paddock near Springs Junction. 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. From the LEARNZ Alpine Fault online field trip… "It might be that it acts as a barrier. The average interval between large quakes on the fault was 330 years. The Alpine Fault runs hundreds of kilometres up the spine of the South Island, from Fiordland along the western edge of the Southern Alps. Howarth said each section had its own characteristics. The Alpine Fault runs almost the entire length of the South Island, and an earthquake there will be felt by much of the country. Researchers have divided the fault into three segments – the South Westland section, from Milford Sound to Jackson Bay; the central section, from there to near Hokitika; and the North Westland section, from Hokitika to Tophouse Flats just past Lake Rotoiti. 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 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. It’s the “on-land” boundary of the Pacific and Australian Plates. The slip rate here was much lower, only about 14mm a year, probably because movement was transferred in the northern section on to the Hope, Awatere and Wairau faults. May 21 2016 “Queenstown conference told of potential impact of alpine fault rupture” Stuff. Take a look at the site where scientists have drilled into the Alpine Fault and find out what they hope to discover. We don't have enough data to say. There was evidence of 27 ruptures in the southern section, with a 291-year recurrence interval and an average slip of about 29mm a year. Mapping has shown the Alpine Fault runs directly under some Franz Josef businesses, including the petrol station, the Helicopter Line offices and part of … Video simulations demonstrate widespread destruction across the South Island if New Zealand's most dangerous fault line ruptures, and there's evidence the country is due for another big one. (File photo), Alpine Fault is better understood – but that won't stop the Big One, Big Bay quake on Sunday largest along Alpine Fault since 2001, New study says Alpine Fault quake interval shorter than thought: GNS Science, Big Alpine Fault quake may be 'in near future', Lunchtime sightseeing trip in new helicopter ends with fatal crash, Transport Agency employee breaching learner licence kills motorcyclist, This could be the worst Parliament since MMP unless urgent changes are made, Pilot injured after helicopter crash in Hawke's Bay, Auckland mum appalled after school staff member put tape on her son's mouth, Quiz: Morning trivia challenge: December 16, 2020, Coastal residents’ fight for their homes comes to an end, Covid-19: Rest home volunteer dressed as Santa infects 75 residents in super-spreader event, In a first, leading Republicans call Joe Biden US president-elect, Distressed investors handed over more than $13m to missing Australian woman Melissa Caddick. Despite its obvious tectonic significance, the Alpine fault has not ruptured since European settlement in the 1840s. Howarth said 1740 was the earliest likely year for the recently discovered quake and it was unlikely to be much later than 1840, otherwise it would have been felt by South Islanders and talked about. Cows in front of the Alpine Fault scarp at Inchbonnie (file photo). The Alpine Fault is the boundary between the Pacific crustal plate and the Australian plate. Scientists have established that the fault … Howarth said they were intrigued about the "big bend" in the Alpine Fault between about Springs Junction and Lake Rotoroa, near St Arnaud, which might help stop a rupture and protect people in Wellington and parts of Marlborough from severe shaking.

[2] Ruptures occurred on multiple faults and the earthquake has been described as the "most complex earthquake ever studied". Stuff has the latest information on this: Videos show devastating impact across South Island if Alpine Fault ruptures Video simulations demonstrate widespread destruction across the South Island if New Zealand’s most dangerous fault line ruptures, and there’s evidence the country is due for another big one. `` Bends like that usually stop earthquakes. `` scarp at Inchbonnie ( file photo ) Wairau River Valley the!
