However, a large number of people will suffer disabling injuries. The Structural Geology of the Alpine Fault . A major problem constraining repair and rebuilding will be the shortage of trades people and materials. Presentation given in Christchurch in March 2015. AF8 [Alpine Fault magnitude 8] is a collaborative effort to save lives by planning and preparing a coordinated response across the South Island after a severe earthquake on the Alpine Fault. magnitude that is much smaller than that expected from the Alpine Fault (Mw=8.2) and that is similar to a potential Hope Fault event (Mw7+). A sudden onset national civil defence emergency of long duration will be called. As these two plates move against each other enormous pressure builds up which must eventually be released through earth movement. The earthquake will last for about two minutes. You are represented by 12 councillors, elected to govern the Council for the people of Otago. There is extensive advice on how to be prepared on www.happens.nz and www.otagocdem.govt.nz. In areas where the magnitude is plus or minus 9, many tens of millions of cubic metres of rock and scree may collapse from slopes. The 2020 New Zealand Earthquake (pronounced "TWENTY-TWENTY", also known as the Alpine Fault Quake and the 2020 South Island Quake) is a magnitude 8.7 earthquake that will occur on the Alpine Fault in New Zealand's South Island at 11:31 (local) on Thursday, June 18th, 2020. Numerous experts say it will be the largest natural disaster of … Evidence is growing the South Island's Alpine Fault, capable of devastating earthquakes of magnitude 8 and above, ruptures more frequently than previously believed. This includes having stored water, food, medical supplies, alternative means of cooking and heating for your household and your pets. Read more. Transalpine routes and roads in mountainous areas will be impassable for weeks, therefore, tourists and other travellers are likely to be stranded. The 1929 Arthur’s Pass earthquake on the Poulter Fault. The 1888 North Canterbury earthquake on the Hope Fault west of Hanmer Springs. 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 earthquake event. Snow on the mountains of the Pacific plate contrasts with the lower land of the Australian plate. Many rivers and streams will become impassable. Read more. Numerous experts say it will be the largest natural disaster of … Spot the fault. 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. Roads will suffer serious damage, some areas will be become isolated immediately. An Alpine Fault earthquake will be felt by every South Islander and likely many North Islanders, too. www.youtube.com/channel/UC3nsXLqxO5OGcYCmEcS56sA. As in any disaster some people may suffer terribly, and others will profit. The Wakatipu including Queenstown could become completely isolated if the airport is damaged. The Alpine Fault last got seriously testy in 1717 or thereabouts and before that, in descending order, 1620, 1430 and 1100. Many other roads will be affected. While the direct impact on people, families and businesses will vary, it is certain that normal life will be disrupted for everyone in the South Island for an extended period afterwards. 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. 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 historical patterns of earthquakes and current research on the Alpine Fault indicate that it is likely to rupture very soon in geological terms. Our Knowledge of the Alpine Fault . The Alpine Fault stretches for hundreds of miles (kilometres) like a spine along New Zealand's South Island. Any actions you take now to be better prepared will make life easier for you and those who rely on you in the aftermath. At this point the surfaces of the two plates making up the South Islands alpine fault meet. The 2016 Kaikoura earthquake, which ruptured parts of The Humps, the Hundalee, Hope, Jordan Thurst, Papatea, Kekerengu and Needles faults. The alpine fault earthquake will alter tectonic stress distribution, and other faultlines may rupture in the days or years following it. It will be felt throughout the South Island and the lower North Island and as far away as Sydney. Find out more. The South Island Alpine Fault Earthquake Response (SAFER) Framework provides a concept of coordination of response and priority setting across all six South Island Civil Defence Emergency Management (CDEM) Groups and their partner organisations in the first seven days of response. The next Alpine Fault earthquake would likely also be a long-duration event – unzipping the crust for as much as three minutes - because of the sheer length of the fault. Electricity supply is likely to be unavailable for many weeks or even months in some remote areas. The Alpine Fault is sometimes compared with California’s San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. An earthquake on the Alpine Fault is likely to be one of the most significant disasters that could affect Selwyn district. The Pacific Plate on the easterly area of New Zealand is moving westwards and the Australian Plate, on the western side of New Zealand moves eastwards. Our environment is our most important asset. It will be centred roughly 60km west of Queenstown, in the South Westland area. Our scientific understanding concerning the next large earthquake on the Alpine Fault, New Zealand. Develop a plan about for what you need in order to be prepared. Provision of emergency medical facilities for many major trauma victims and the rescue of trapped people on roads will be severely disrupted for 3-4 weeks. Their location, on either side of the fault, has helped us understand how the Alpine Fault moves in an earthquake. Image / GNS Science People trapped on roads and tracks, or in accommodation will need to be looked after where they are for days due to road blockages, airport damage, and limited means of transportation. It will be centred roughly 60km west of Queenstown, in the South Westland area. View the latest news and events from Otago Regional Council. Encourage others to do likewise. You will find the SAFER Plan for this response on the Project AF8 website www.projectaf8.co.nz. Find out more about what rates are used for and how to pay them. Check on the Emergency Management Otago website to see whether the area you live has a community response plan. Alpine Fault movement. 3. 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. A study by the U.S. Geological Survey indicates that a portion of the San Andreas fault near Tejon Pass could be overdue for a major earthquake. Damage in other parts of Otago will be irregularly distributed depending on the land forms and the built environment. This earthquake is a normal part of New Zealand's evolution. Depending on the time of year, the large number of seasonal visitors in the Queenstown Lakes District and other parts of Otago will be completely reliant on immediate assistance. The last such earthquake took place in … Cessation of most commercial activity may occur in many parts of the South Island, however, many local economies will be maintained solely by recovery activities. The Red Hills, Fiordland This view is looking northward, from Fiordland up along the West Coast of the South Island.
