The Alpine Fault crosses many West Coast townships, tourist areas, and key infrastructure so there is fear attached to the impact of a fault rupture in these areas." The Alpine Fault is the boundary between the Pacific crustal plate and the Australian plate. 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. They say it is too early to tell how their discovery may change the probabilities of when the next big, possibly magnitude 8-plus, Alpine Fault quake is due. The fault crosses Lake Rotoiti and the Brunner Peninsula before striking northeast up the Wairau River Valley as the Wairau Fault. 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. 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. GNS details on the Alpine Fault The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. This news article from Stuff covers some research on the frequency of past earthquakes along the Alpine fault.

Stuff.co.nz: Scientists mark 300 years since last great Alpine Fault quake – preparing for the ‘inevitable’ Otago Daily Times: Alpine shake would hit tourism Newshub: Alpine Fault overdue for magnitude 8+ quake – scientists But there was only evidence of two ruptures in the "under-studied" northern section, which meant a robust recurrence internal could not be calculated. Scientists have established that the fault … In Christchurch, the shaking from an Alpine Fault rupture might not feel as sharp as the February 2011 earthquake, Bradley said, but it would last a lot longer – about two or three minutes. It's a puzzle. The average interval between large quakes on the fault was 330 years. A companion set of longer videos provide more in-depth detail of the science underpinning ProjectAF8, which is funded by the Ministry of Civil Defence & Emergency Management and through the Resilience to Nature's Challenges Fund. 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. “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. 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. From the LEARNZ Alpine Fault online field trip at… GNS Science earthquake geologists studying layers in the trench across the Alpine Fault at Calf Paddock near Springs Junction. Shaking near the epicentre, not far from Haast, would be unlike any felt in modern New Zealand history. 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. "We would like to make sure that you are prepared for a large earthquake at all times." October 14 2016 “When, not if: Alpine fault could cause 8 metres of movement” "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. "Bends like that usually stop earthquakes.". The southern part of the fault has been found to rupture on average every 291 years, plus or minus 23 years, and there is a 27 per cent chance of that happening again in the next 50 years. Conference delegates were updated on … 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.

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 … 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. 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. The Alpine Fault from Mount Robert above St Arnaud. In the past 8000 years it had ruptured 24 times and caused magnitude-8 quakes, including four in … 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 Alpine Fault is the boundary between the Pacific crustal plate and the Australian plate. 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. "It might be that it acts as a barrier. 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.". 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). 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. To the West of the fault Paleozoic basement rocks are interluded by plutones and both are unconformably covered in a sedimentary sequence. The last rupture was believed to have happened in 1717. 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. Howarth said each section had its own characteristics.
