The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. The seismologist on duty at Geonet said the quake appeared to have occurred on the Alpine Fault. The council's emergency management team has been working with Selwyn communities to get ready. 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. For much of its length, it runs through steep, inaccessible, and bush-clad country. The first four videos are shorter, and the next four are more detailed and longer format. Project AF8, the South Island-wide effort to coordinate planning and preparation for a severe earthquake on the Alpine Fault, has released a series of short videos to mark the end of the first two years of its work. But new evidence of a 19th century earthquake indicates that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events. Numerous experts say it will be the largest natural disaster of … Drive out to Ōkārito to look at how people and the environment will be affected by an Alpine Fault Earthquake. . The Alpine Fault trace is a low scarp cutting across calf paddock , J.Thomson / GNS.Science. 24 May 2018. New evidence of a 19th century earthquake on New Zealand's Alpine fault suggests that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events. Jack was part of a team of experts that went into the field immediately following the Kaikoura earthquake to map the surface ruptures. During the field trip follow the line of the Alpine Fault as it is crossed by roads, bridges, rivers, mountains, power lines, and phone lines from Arthur's Pass to Whataroa on the West Coast. Project AF8 is a collaborative effort to prepare for a magnitude 8 Alpine Fault earthquake. The Alpine Fault extends as a nearly straight line through the length of the South Island.

J ack Williams is a PhD Student at the University of Otago, New Zealand, where he is studying the Alpine Fault. The fault line is where the Eurasian … Each of the marks on the chart represents the date of a past Alpine Fault earthquake. Background Readings for The Alpine Fault. A rupture along the full length of the fast-slipping Alpine Fault on New Zealand’s South Island poses the largest potential seismic threat to the southern and central parts of the country. Alpine Fault Project Releases Video Series. The Alpine Fault is spectacularly marked out on satellite images by the western edge of the Southern Alps snowline. A graphic shows an indicative line of the Alpine Fault in relation to Wanaka and Queenstown. Emergency Management Otago. From the LEARNZ Alpine Fault online field trip at… It runs for 650 kilometres along the spine of … Download. The lengthy Alpine Fault, which runs along the spine of the Southern Alps, has garnered much attention as it has a clear geographic record of rupturing every 300 years or so. Fault ruptures (earthquakes) have displaced river terraces that cross the fault. Cross the Alpine Fault at Inchbonnie and find out how scientists can learn more about a fault and the earthquakes that it generates. Fault line . Links. Preparing for an Alpine Fault earthquake. The borehole that was drilled will be used for further research, including to monitor changes over the years. The South Island Alpine Fault Earthquake Response (SAFER) Framework is the result of two years of effort by AF8, a collaboration between all the South Island’s Civil Defence Emergency Management Groups, scientists and partner agencies. An Alpine Fault earthquake will likely rupture a larger fault length (several hundreds of kilometres rather than several tens of kilometres) over a longer period of time (100s of seconds rather than tens of seconds) and affect a much larger area than the Darfield earthquake. The marks don’t show an exact date because we can’t be that accurate. 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. "This fault system has the potential for larger events," Geonet tweeted. Recent research has found that the average time between large earthquakes on the fault is 330 years. The Alpine Fault runs right through the heart of New Zealand's glacier county on the country's south island. It is the boundary between the Pacific … The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. The Alpine Fault runs for about 600km along the west of the Southern Alps. A study of sediment layers in the Southern Alps has offered new insights into the likelihood of the Alpine Fault generating a large earthquake in our lifetimes, making headlines here and overseas. A wall has been built across the fault scarp to check for movement. Alpine Fault Project Releases Video Series to Mark Major Milestone. Here he explains what they were up to and shares some photos of the damage. The Alpine Fault is sometimes compared with California’s San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. Alpine Fault. The last major earthquake on the Alpine Fault was in 1717, so we're already a little overdue for one of the biggest earthquakes in New Zealand's modern history. The 300-year anniversary of the last time the Alpine Fault ruptured has been marked with a special issue of the New […] Continue reading Why it’s so important to mark the anniversaries of earthquakes – Ursula Cochran LEARN ABOUT IT. . A new model has simulated the disruption a major Alpine Fault earthquake would have on the South Island's transport network - cutting off the West Coast for at least a week. Alpine Fault Project Releases Video Series to Mark Major Milestone. It has been funded by the Ministry of Civil Defence & Emergency Management and Resilience to Nature’s Challenges. Here is the complete series of videos which have been produced by the AF8 Project. It’s the "on-land" boundary of the Pacific and Australian Plates. Image showing the Alpine Fault running up the western side of the South Island. AF8 [Alpine Fault magnitude 8] is again teaming up with leading earthquake scientists and Civil Defence Emergency Management (CDEM) Groups … 'Boost for the West Coast' In this video Dr. Ursula Cochran shows us how the evidence from Hokuri Creek and John O'Groats has increased our knowledge of Alpine Fault earthquakes. The research, published today in the leading journal Science , presents a revised timeline of earthquakes occurring on the alpine faultline dating back 8,000 years. Another Alpine Fault earthquake uplifts the scarp, and a new earthquake debris layer is deposited, adding another record to the fault rupture history. PHOTO: PROJECTAF8.CO.NZ “What we know about the Alpine Fault is that it tends to produce big earthquakes, roughly every 300 years,” Dr Orchiston said. The videos are intended to both warn and educate our community about the overdue Alpine Fault earthquake which is expected to be in the magnitude 8 range.
