earthquake 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. 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. Civil Defence Emergency Management Groups across the South Island are working together to plan a coordinated response to the next severe Alpine Fault earthquake. Large sections of SH6 (Haast Highway) may be out for up to a year. The Alpine Fault connects two "subduction" margins where the ocean floor descends into the Earth's mantle. This includes having stored water, food, medical supplies, alternative means of cooking and heating for your household and your pets. You can pick out the line of the Alpine Fault on this satellite image of the South Island. Significant building damage can be expected in the Queenstown Lakes District. The Resource Management Act sets out how we should manage our environment and forms the foundation for the majority of our work. https://phys.org/news/2020-12-seismic-zealand-alpine-fault-complex.html A study released by NIWA in 2018 found evidence of tsunami up to 5m high caused by landslides into Lake Tekapo, which scientists believe will be similar to other large Otago Lakes: www.niwa.co.nz/news/lake-tekapo-study-raises-awareness-of-tsunamis-in-nz-lakes.

However, most of the motion on the fault is strike-slip (side to side), with the Tasman district and West Coast moving North and Canterbury and Otagomoving South. Presentation given in Christchurch in March 2015. Future Earthquake Predictions. Numerous experts say it will be the largest natural disaster of … Earthquake hits South Island's Alpine Fault; How large? 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. 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. We provide bus services in Queenstown and Dunedin to help you get to where you need to go. The nature and location of the earthquake relative to major population centres suggest that a relatively small number of people will be killed. Front page photograph: The Alpine Fault at Inchbonnie – Hohonus and Taramakau River looking east [L.Homer, GNS] M Trayes, Natural Hazards Analyst West Coast Regional Council February 20 12 Alpine has had: (M1.5 or greater) 1 earthquake in the past 24 hours 7 earthquakes in the past 7 days; 29 earthquakes in the past 30 days; 767 earthquakes in the past 365 days You can find the application forms here. An Alpine Fault earthquake will be felt by every South Islander and likely many North Islanders, too. The Alpine Fault ruptures—on average—every 330 years with a magnitude 8 earthquake. A sudden onset national civil defence emergency of long duration will be called. The effects will be amplified in South Island mountainous regions and high country where enormous damage can occur to peaks and ridges. Look at your home, property or business and develop scenarios about the risk factors. Carbon dating confirms that the last severe earthquake on the Alpine Fault was in 1717. The Alpine Fault runs for about 600km up the spine of the South Island, and is one of the world’s major geological features. The earthquake will last for about two minutes. The Alpine Fault stretches for hundreds of miles (kilometres) like a spine along New Zealand's South Island. The 1888 North Canterbury earthquake on the Hope Fault west of Hanmer Springs. Electricity supply is likely to be unavailable for many weeks or even months in some remote areas. Agricultural production will be disrupted, and dairy herds may be unable to be milked in some areas due to electricity outage. The length of the rupture will be up to 400 km, eg. The effects will be worst in West Otago, diminishing eastward. The map below indicates the range of the earthquake and its shaking intensity (shown in Roman numerals). 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. We work with the community to ensure the sustainable use of our natural resources. Magnitude 8 or larger, geologists said in a special edition of the New Zealand Journal of Geology and Geophysics last year. GNS scientists have calculated a 30% likelihood of the fault line rupturing in the next 50 years. Our Knowledge of the Alpine Fault . The best paleoseismic evidence to date suggests the southern and central sections of the Alpine Fault, at the boundary separating the Australian and Pacific tectonic plates, typically rupture during very large full-section earthquakes of magnitude 7.7 or larger. on Haast and spreading north to Ahaura. Presentation given in Christchurch in March 2015. Less intense shaking from aftershocks will continue for months. It will be centred roughly 60km west of Queenstown, in the South Westland area. View our live rainfall, river flow and ground water data. The Alpine Fault last got seriously testy in 1717 or thereabouts and before that, in descending order, 1620, 1430 and 1100. In the same way that the 2016 Kaikoura earthquake caused massive landslides to block SH1 for over a year, an Alpine Fault rupture will cut road access through the Kawarau Gorge, Kingston to Frankton, Haast Pass and the Glenorchy Road may be cut in many places, mostly by landslides and dropouts. 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. Plan to be self-reliant for at least three days – a week or more is realistic. Using techniques like these, scientists such as Mark Yetton of the University of Canterbury have found out that major earthquakes happened on the central Alpine Fault in 1100, 1450, 1620 and 1717. www.youtube.com/channel/UC3nsXLqxO5OGcYCmEcS56sA. Get all the information you need to get around Dunedin. An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. Alpine has had: (M1.5 or greater) 1 earthquake in the past 24 hours 7 earthquakes in the past 7 days; 29 earthquakes in the past 30 days; 767 earthquakes in the past 365 days The alpine fault earthquake will alter tectonic stress distribution, and other faultlines may rupture in the days or years following it. 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. 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. Any actions you take now to be better prepared will make life easier for you and those who rely on you in the aftermath. The pressure has been continually building for about 280 years since it was last released by a large earthquake in 1717 AD. 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. This is not a regular pattern, but enough to suggest there is a high probability of a large earthquake … The Alpine Fault is sometimes compared with California’s San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. They move at a relative rate of about 45mm per year. 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. 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. "By comparison, the Kaikōura Earthquake in 2016 ruptured a total fault length of 200km in the space of about two minutes," said Holden. At present, the response spectra from a great scenario earthquake from the Alpine fault can only be estimated from groundmotion - prediction equations (GMPEs) based on local and overseas earthquake records. Our scientific understanding concerning the next large earthquake on the Alpine Fault, New Zealand. With an expected magnitude of 8+ this will be considered a "great earthquake" not simply a strong one. Two very large earthquakes or a series of large earthquakes are also realistic scenarios. We are a young country and learning to adapt to it is a necessity if you and your community are to get through. It will be felt throughout the South Island and the lower North Island and as far away as Sydney. There is extensive advice on how to be prepared on www.happens.nz and www.otagocdem.govt.nz.
