stuff alpine fault

(File photo), Investigations of the Alpine Fault at Inchbonnie near the Taramakau River have been carried out by studying trenches dug across the fault and by using ground-penetrating radar. The geology of the West Coast of New Zealand's South Island is divided in two by the Alpine Fault, which runs through the Region in a North-East direction. The Marlborough Fault System is a set of four large dextral strike-slip faults and other related structures in the northern part of South Island, New Zealand, which transfer displacement between the mainly transform plate boundary of the Alpine fault and the mainly destructive boundary of the Kermadec Trench, and together form the boundary between the Australian and Pacific Plates. The Alpine Fault runs almost the entire length of the South Island, and an earthquake there will be felt by much of the country. 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 Just-released videos have shown what would happen in the event of a major quake along the South Island's big-risk Alpine Fault. The 2016 Kaikoura earthquake was a magnitude 7.8 (Mw) earthquake in the South Island of New Zealand that occurred two minutes after midnight on 14 November 2016 NZDT (11:02 on 13 November UTC). From the LEARNZ Alpine Fault online field trip at… "We have used that scenario to work with our partners to identify the foreseeable impacts on communities and critical infrastructure across the South Island," he said. "Bends like that usually stop earthquakes.". Despite its obvious tectonic significance, the Alpine fault has not ruptured since European settlement in the 1840s. It released the four two-minute videos to mark two years of work. They say it is too early to tell how their discovery may change the probabilities of when the next big, possibly magnitude 8-plus, Alpine Fault quake is due. The Alpine Fault runs hundreds of kilometres along the western Alps from Marlborough to Milford Sound, where it heads offshore, and marks the Pacific and … The southern part of the fault has been found to rupture on average every 291 years, plus or minus 23 years, and there is a 27 per cent chance of that happening again in the next 50 years. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. Scientists question whether a 5.5 quake did indeed strike on the big-risk Alpine Fault.

Ms Cooper lives near the Alpine Fault, which is likely to rupture within the lifetime of many New Zealanders. 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. Project AF8 have been preparing for a severe earthquake on the Alpine Fault for two years. It runs northeast from the northern side of the entrance to Milford Sound, along the western side of the Southern Alps for about 800 kilometres before morphing into the Marlborough fault system beyond St Arnaud. Take a look at the site where scientists have drilled into the Alpine Fault and find out what they hope to discover. Instead, they have evidence from the back country behind Hokitika that the northern part of the fault ruptured more recently, sometime between 1740 and 1840, possibly generating a quake with a magnitude of 7.0 to 7.5. In the past 8000 years it had ruptured 24 times and caused magnitude-8 quakes, including four in … [2] Ruptures occurred on multiple faults and the earthquake has been described as the "most complex earthquake ever studied".

The Alpine Fault from Mount Robert above St Arnaud. The central section had evidence of eight events with a return period of 263 years plus or minus 68 years and slip of 28mm a year. EPL Ltd owner Tom Thomson talks about the challenges he faced after the February 2011 earthquakes in Christchurch. ProjectAF8 is a South Island-wide effort to co-ordinate planning and preparation for a severe earthquake on the fault. The Alpine Fault ruptures—on average—every 330 years with a magnitude 8 earthquake. The two quakes they had found evidence for were the big quake in 1717 and the more recent quake, sometime between 1740 and 1840, he said. Painstaking work by Victoria University of Wellington palaeoseismologist Dr Jamie Howarth and GNS Science senior earthquake scientist Dr Rob Langridge casts doubt on 1717 as the last time the fault caused a major earthquake. Project Alpine Fault Magnitude 8 (AF8) released a series of videos on Wednesday, warning there's compelling geological evidence to show it produces a significant earthquake of magnitude eight or greater every 300 years on average. Studies at Alpine Fault excavation sites showed a large earthquake occurred on the fault every 300 years or so, with the last one occurring in 1717. But there was only evidence of two ruptures in the "under-studied" northern section, which meant a robust recurrence internal could not be calculated. More work was being done to refine the date of that last quake. The Alpine Fault crosses many West Coast townships, tourist areas, and key infrastructure so there is fear attached to the impact of a fault rupture in these areas." Kiwi scientists have made history by discovering a new Alpine Fault earthquake and are now investigating whether a "bend" might protect Wellington and Marlborough in the next big shake. The fault crosses Lake Rotoiti and the Brunner Peninsula before striking northeast up the Wairau River Valley as the Wairau Fault. Video simulations demonstrate widespread destruction across the South Island if New Zealand's most dangerous fault line ruptures, and there's evidence the country is due for another big one. "We would like to make sure that you are prepared for a large earthquake at all times." The slip rate here was much lower, only about 14mm a year, probably because movement was transferred in the northern section on to the Hope, Awatere and Wairau faults. 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.

It's about whether that provides some protection for those population centres in Marlborough and Wellington further down the fault. The Alpine Fault runs northeast from the northern side of the entrance to Milford Sound, along the western side of the Southern Alps for about 800 kilometres before morphing into the Marlborough fault system beyond St Arnaud.
