what will happen if the alpine fault ruptures

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 for a severe magnitude eight earthquakes. Less people live close to the Alpine Fault but the shaking could cause widespread Two Suns Theory, Kali Yuga Cycle Completes 2025, David Wilcock: Pete Peterson's "Deathbed Confessional" on Secret Space Programs, Lockheed CEO Ben Rich Declared On His Death Bed: Extraterrestrial UFO Are Real, Bombshell Interview Exposes Reptilian Control of Earth - Part 1, Huge Slow Moving, Cylindrical UFO Recorded in El Paso, Texas, Unusual Deep Space Signals in Antarctica May Indicate Existence of Parallel Universe. The fault runs diagonally through Franz Josef Township and geologists have recommended a “fault avoidance zone” 100 meters either side to protect buildings.

Just as the Kaikōura earthquake in 2016 had a significant impact on Wellington, we expect that when the Alpine Fault ruptures in a large magnitude earthquake it will be widely felt across the lower North Island. . The Alpine Fault has a high probability (estimated at 30%) of rupturing in the next 50 years. An Alpine Fault rupture may trigger landslides and flooding especially on the West Coast which could be cut off for a while and hard to it will be hard to support them. Other problems were more likely to be an issue, such as damage to underground pipes, and major landslides along the South Island’s main highways. He hoped public pressure on the Government would result in action. In between earthquakes, the Alpine Fault is locked. "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?". Towns and cities throughout the South Island will feel its tremendous power, with those on the West Coast taking most of its brunt. The geology of New Zealand makes that an incredibly complex question to answer - but a new study evaluating millions of different earthquake scenarios will give us a much better idea. CHECK OUT OUR EDITOR'S LIST OF MUST READ ARTICLES, Editor’s Addition: The Alpine Fault is a geological fault, specifically a right-lateral strike-slip fault, that runs almost the entire length of New Zealand’s South Island. – Food and water for at least three days. 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". NASA Finds Keyhole-shaped Structure on Mars Too Difficult to Explain! The Alpine Fault • Running about 600km up the spine of the South Island, the Alpine Fault is the on-land boundary of the Pacific and Australian tectonic plates. "By comparison, the Kaikōura Earthquake in 2016 ruptured a total fault length of 200km in the space of about two minutes," said Holden. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. "When the Alpine Fault next ruptures, it will produce seismic waves that propagate out in all directions," Townend said. The rupture will produce one of the biggest earthquakes since European settlement of New Zealand, and it will have a major impact on the lives of many people. When an earthquake happens the ground moves on one side of the fault relative to the other. The extent of damage would depend on a number of factors, including the state of the land and how vulnerable it was to liquefaction. "This means that we can investigate a far more comprehensive range of scenarios that take into account the latest information we have about the fault's current state, and obtain realistic probabilistic estimates of the shaking that will occur in inevitable future large Alpine Fault earthquakes.". The fault, which runs about 600km up the western side of the South Island, poses one of the biggest natural threats to New Zealand. The Alpine Fault is a big feature of South Island geography and seismic activity. AND BE SURE TO JOIN OUR FORUM TOO! The Alpine Fault is expected to rupture within 50 years, a one-in-500 year event that will produce a devastating earthquake of a magnitude 8 or more. 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. Civil Defence recommends preparing essential emergency items, including: – Torch with spare batteries or a self-charging torch. At 3 AM on May 29, 2013, the South Island’s technological uncon­scious roars […] But good behaviour, in a scientific sense, may not bring much comfort to South Islanders. The novelty of this approach is that calculating how different patterns of slip on the fault affected ground shaking at locations of interest throughout the South Island and southern North Island could be done without having to simulate the entire wave propagation process. – Toilet paper and large rubbish bags for your emergency toilet. Post was not sent - check your email addresses! The Los Angeles aqueduct could be fortified so that it won’t break when the San Andreas ruptures. "Given what we know from geological studies of the Alpine Fault, we're anticipating a major magnitude 8.0-plus earthquake, rupturing 500km of the crust, so the shaking will be felt throughout the South Island, but the intensity and duration will ultimately depend on what happens on the fault.". WE ENCOURAGE YOU TO REGISTER, LET'S BUILD A GREAT COMMUNITY TOGETHER It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. In earthquake terms, t SIGNING UP IS FAST, EASY AND FREE (TAKES LESS THAN A MINUTE AND IT'S A FREE FORUM), CLICK IMAGE FOR VIDEO, MAP & ARTICLE LINKS, All of the clocks in the movie Pulp Fiction are stuck on 4:20, IF YOU ENJOY THIS SITE PLEASE TELL OTHERS ABOUT US…SHARING IS CARING. The central and southern parts of the Alpine Fault run for about 400 kilometres up the spine of the South Island, and are about 40 times longer than the fault responsible for the fatal February 2011 earthquake in Christchurch. Simulation shows widespread damage if Alpine Fault ruptures. It has ruptured four times in the last 900 years, resulting in earthquakes of around magnitude 8, and is now considered highly probable to go again in the next 50 years. 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. This study builds upon previous investigations in order to develop a better chronology of large earthquakes generated by ruptures on the Alpine Fault. The Alpine Fault, which runs about ... 3D picture of the ground shaking effects we could expect from future large earthquakes on the fault. An Alpine Fault earthquake will: 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. – Wind and waterproof clothing, sun hats, and strong outdoor shoes. Photo / Getty Images. Sorry, your blog cannot share posts by email. The Alpine Fault ruptures—on average—every 330 years with a magnitude 8 earthquake. . 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. "It looks pretty random but embedded in the incoherence are useful signals that tell us how seismic waves propagate between different parts of the Alpine Fault and, say, locations in Christchurch or Nelson or wherever you like.". "But we haven't yet witnessed a rupture of this fault ourselves, so our understanding of what ground motions it will produce is based on hypotheses about how much of the fault ruptures, how fast, and to what depth... and the elastic properties of the Earth," he said. by removing some of the really susceptible parts [of the hills],” he said. The project has now also completed its draft South Island Alpine Fault Earthquake Response (SAFER) framework, which puts into place procedures for when the enormous fault ruptures. The 600-kilometre fault has ruptured five times in the past 1100 years. 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. 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. 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. Scientists say the intensity of the shaking in the most affected areas - particularly West Coast spots - could be unlike anything we've felt before. “Now that we have that understanding, we can prepare for it better, and hopefully we can lessen the impact it has on us as a society.”.

The next major rupture of the South Island's Alpine Fault will prove one of the largest - if not the biggest - that earthquakes Kiwis have ever experienced. 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. Video simulations demonstrate widespread destruction across the South Island if … This happens with incredible regularity around every 300 years, on average. Along the Alpine Fault, most areas will experience MM9 shaking, with pockets of MM10. The new study is being supported with a $960,000 grant from the Marsden Fund. The San Andreas fault is overdue for a major earthquake also known as "The Big One." 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.
