what will happen if the alpine fault ruptures

SUPPORT BENDEDREALITY- MAKE A DONATION TODAY, WE ENCOURAGE YOU TO REGISTER, LET'S BUILD A GREAT COMMUNITY TOGETHER. The Alpine Fault is a big feature of South Island geography and seismic activity. The Alpine Fault runs 400km up the South Island, along the western edge of the Southern Alps. Towns and cities throughout the South Island will feel its tremendous power, with those on the West Coast taking most of its brunt. The new study is being supported with a $960,000 grant from the Marsden Fund. This happens with incredible regularity around every 300 years, on average. Sorry, your blog cannot share posts by email. It last ruptured in 1717 and there is a big earthquake, on average, about every 300 years, but the times vary so there is thought to be about a 30% risk of the next ‘Big One’ in the next fifty years. AND BE SURE TO JOIN OUR FORUM TOO! It would also be no particular surprise if it didn’t happen for another 50 years; unlike we impatient humans, a fault would hardly know the difference. It has a clear geologic record of rupturing around every three centuries - and 2017 marked the 300th anniversary of what is thought to have been a magnitude 8 quake that moved one side of the fault by about 8m in a matter of seconds. a smaller group of scientists drilled two boreholes to about 150m into the fault, also near Whataroa, in early 2011. Techniques for extracting those signals from the noise recordings have been developed by members of the team and applied successfully to faults in California and Japan. In between earthquakes, the Alpine Fault is locked. While we can’t predict when earthquakes will occur, scientific research has shown that the Alpine Fault has an remarkably regular history of producing large earthquakes. 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. Scientists, working as part of Project Alpine Fault Magnitude 8 (AF8), have marked the end of their first two years of work planning and preparing … #newzealand FOLLOW US ON FACEBOOK, TWITTER , OR SUBSCRIBE TO OUR BLOG SO YOU NEVER MISS NEWLY POSTED ARTICLES OR IMPORTANT ALERTS! GNS science said there was a 30 per cent chance of a large earthquake on the Alpine Fault in the next 50 years. by removing some of the really susceptible parts [of the hills],” he said. Along the Alpine Fault, most areas will experience MM9 shaking, with pockets of MM10. "Much of what we record with seismometers is noise generated by ocean waves," he said. WE ENCOURAGE YOU TO REGISTER, LET'S BUILD A GREAT COMMUNITY TOGETHER Simulation shows widespread damage if Alpine Fault ruptures. UC PhD graduate Tom Robinson investigated what would happen in a magnitude 8.0 event on the Alpine Fault, which has about a one-in-three to one-in-four chance of occurring in the next 50 years. The alpine fault earthquake will alter tectonic stress distribution, and other faultlines may rupture in the days or years following it. "This enables us to compute realistic ground-shaking in population centres and at other vulnerable locations in response to many more earthquake rupture scenarios than can be practicably studied using conventional approaches," Townend said. By analysing sediment deposited at two sites in Fiordland – John O’Groats and Hokuri Creek – during previous earthquakes, scientists have established that the Alpine Fault has ruptured 27 times over the last 8000 years. . Devastated friends try to piece together chopper tragedy that killed couple, Desert Rd murder case: 'Naive' only child helped dispose of man's body, Multiple people trapped after car and truck crash, Seven fire trucks battled house fire in Pakipaki, near Hastings, Watchdog warns Noel Leeming over fast delivery promises. He hoped public pressure on the Government would result in action. "By analysing these rupture scenarios mathematically, you can calculate the ground shaking in different places – but you can realistically only do that for a limited range of scenarios because simulating the propagation of seismic waves through complex geological structures is a very large computational task.". Dr Caroline Orchiston explains the Alpine Fault and the damage the earthquake will have. As part of a lead-up to this year’s project. "What we're interested in is, how do variations in the likely characteristics of the earthquake affect ground shaking at different locations in the country?". The Alpine Fault, which runs about 600km up the western side of the South Island between Milford Sound and Marlborough, poses one of the biggest natural threats to New Zealand - especially the West Coast, Canterbury and Otago. Less people live close to the Alpine Fault but the shaking could cause widespread That said, from what we do know, there will be a large earthquake on the Alpine fault in the not-too-distant geological future, and it would be no surprise if it happened tomorrow. The key to evaluating a broader range of earthquake rupture scenarios could lie in newly-developed methods of extracting information from background seismic noise - or what Townend called the Earth's "hum". "When the Alpine Fault next ruptures, ... but the intensity and duration will ultimately depend on what happens on the fault." From there, the Alpine Fault runs along the western edge of the Southern Alps, before splitting into a set of smaller dextral strike-slip faults north of Arthur’s Pass, known as the Marlborough Fault System.
