It's a puzzle. 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. [2] Ruptures occurred on multiple faults and the earthquake has been described as the "most complex earthquake ever studied". 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. AF8 [Alpine Fault Magnitude 8] is an award-winning programme of scientific modelling, response planning and community engagement designed to build a collective resilience and preparedness to the next Alpine Fault EPL Ltd owner Tom Thomson talks about the challenges he faced after the February 2011 earthquakes in Christchurch. The Alpine Fault, which runs up the spine of the South Island, has ruptured five times in the past 1100 years - producing an earthquake of between magnitude 7 … The Alpine Fault runs northeast from the northern side of the entrance to Milford Sound, along the western side of the Southern Alps for about 800 kilometres before morphing into the Marlborough fault system beyond St Arnaud. In this recording, Alpine fault drilling, part of Te Papa’s Science Express programme, hear about the deepest fault drilling ever done in New Zealand. The massive Alpine Fault is due for another big earthquake and scientists have been drawing up a scenario of what the devastation would look like. Just-released videos have shown what would happen in the event of a major quake along the South Island's big-risk Alpine Fault. “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. It’s the “on-land” boundary of the Pacific and Australian Plates. It would be more of a rolling motion for people in Christchurch, because of their distance away from the fault… (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. 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. The four videos … The 2016 Kaikoura earthquake was a magnitude 7.8 (Mw) earthquake in the South Island of New Zealand that occurred two minutes after midnight on 14 November 2016 NZDT (11:02 on 13 November UTC). Highest point Peak Aoraki / Mount Cook Elevation 3,724 m (12,218 ft) Coordinates Dimensions Length 500 km (310 mi) Geography Location South Island, New Zealand The Southern Alps / Kā Tiritiri o te Moana is a mountain range extending along much of the length of New Zealand's South Island, reaching its greatest elevations near the range's western side. Project AF8 have been preparing for a severe earthquake on the Alpine Fault for two years.

Painstaking work by Victoria University of Wellington palaeoseismologist Dr Jamie Howarth and GNS Science senior earthquake scientist Dr Rob Langridge casts doubt on 1717 as the last time the fault caused a major earthquake. It could be a lower-magnitude local rupture in the [magnitude] 6s, or it could have ruptured a larger part of the North Westland section and be in the low [magnitude] 7s.". "But we don't really know any more than that. [Chapter Break] After their ground breaking paper on the Alpine Fault, Willett 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. [1] The Southern Alps have been uplifted on the fault over … 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. Cows in front of the Alpine Fault scarp at Inchbonnie (file photo). 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. Howarth said each section had its own characteristics. Dr Caroline Orchiston explains the Alpine Fault and the damage the earthquake will have. Explanation of how Civil Defence will respond to a significant emergency and how to stay prepared. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. Studies at Alpine Fault excavation sites showed a large earthquake occurred on the fault every 300 years or so, with the last one occurring in 1717. 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. It runs northeast from the northern side of the entrance to Milford Sound, along the western side of the Southern Alps for about 800 kilometres before morphing into the Marlborough fault system beyond St Arnaud. Scientists have established that the fault … Mapping has shown the Alpine Fault runs directly under some Franz Josef businesses, including the petrol station, the Helicopter Line offices and part of … 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. (File photo). "Bends like that usually stop earthquakes.". "It might be that it acts as a barrier. Despite its obvious tectonic significance, the Alpine fault has not ruptured since European settlement in the 1840s. What to expect when the Alpine Fault ruptures” Stuff. GNS Science earthquake geologists studying layers in the trench across the Alpine Fault at Calf Paddock near Springs Junction. "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 Alpine Fault runs almost the entire length of the South Island, and an earthquake there will be felt by much of the country. The last rupture was believed to have happened in 1717. The central section had evidence of eight events with a return period of 263 years plus or minus 68 years and slip of 28mm a year. "The next step is to plan in more detail for a coordinated response to those impacts and the extensive disruption they will cause. The Alpine Fault. This news article from Stuff covers some research on the frequency of past earthquakes along the Alpine fault. More work was being done to refine the date of that last quake. The Alpine Fault runs hundreds of kilometres up the spine of the South Island, from Fiordland along the western edge of the Southern Alps. The Alpine Fault is the boundary between the Pacific crustal plate and the Australian plate.
