Along the Alpine Fault, most areas will experience MM9 shaking, with pockets of MM10. Explore the Alpine Fault, one of Earth's most impressive geological features, where a big earthquake happens about every 300 years and where one is likely in our lifetimes. Recent research (published in 2012) by GNS Science has extended our knowledge of the Alpine fault earthquake record back through the past 8000 years. The shaking in Christchurch, as some below have identified, will be slow and rolly, you will not reach the intensity that the greendale sequence did and definitely not Feb 22 levels. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. 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. Just-released videos have shown what would happen in the event of a major quake along the South Island's big-risk Alpine Fault. by removing some of the really susceptible parts [of the hills]," he said. All these things mean that the Alpine Fault is a globally significant geological structure. In between earthquakes, the Alpine Fault is locked. Scientists digging into new part of South Island's Alpine Fault, Rainwater could be weakening alpine fault, Alpine Fault moves more than any other fault in the world, Alpine Fault spreads across South Island, researchers say, When, not if: Alpine fault could cause 8 metres of movement, Lunchtime sightseeing trip in new helicopter ends with fatal crash, Transport Agency employee breaching learner licence kills motorcyclist, This could be the worst Parliament since MMP unless urgent changes are made, Pilot injured after helicopter crash in Hawke's Bay, Auckland mum appalled after school staff member put tape on her son's mouth, Quiz: Morning trivia challenge: December 16, 2020, Covid-19: Rest home volunteer dressed as Santa infects 75 residents in super-spreader event, Distressed investors handed over more than $13m to missing Australian woman Melissa Caddick, In a first, leading Republicans call Joe Biden US president-elect, Coastal residents’ fight for their homes comes to an end. - Wind and waterproof clothing, sun hats, and strong outdoor shoes. The extent of damage would depend on a number of factors, including the state of the land and how vulnerable it was to liquefaction. and Goff, J. He hoped public pressure on the Government would result in action. Alpine Fault Project Releases Video Series to Mark Major Milestone. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. and Goff, J. In earthquake terms, t Click here for more details of these findings. Earthquakes along the fault, and the associated earth movements, have formed the Southern Alps. The Alpine fault, on New Zealand's South Island, is a large oblique-thrust fault that causes magnitude 7.9 earthquakes every few centuries. But good behaviour, in a scientific sense, may not bring much comfort to South Islanders. Bradley said emergency resources would be stretched if a major earthquake struck, and people could expect to "feel far more alone". There is also another that in its own way is relevant to Christchurch – showing what WILL happen when the Alpine fault goes next time. A big quake on the Alpine Fault could block South Island highways in more than 120 places and leave 10,000 people cut off, new research has estimated. part of Project AF8 (Alpine Fault magnitude 8). The Alpine Fault: when AF8 goes big! He stressed the importance of being prepared, as main roading routes between Canterbury and the West Coast could be cut off. ©NASA. 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. - Food and water for at least three days. on Haast and spreading north to Ahaura. Scientists are trying to understand how the Alpine Fault works and how a really big … 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. The Alpine Fault ruptures—on average—every 330 years with a magnitude 8 earthquake. New research out today reveals that the Alpine Fault - a strike-slip fault running almost the entire length of the South Island - is surprisingly "well-behaved" in its regularity.
