alpine fault earthquake effect on dunedin

Alpine Fault; Climate; Controlled Source Seismology; Earthquake science; Economic geology; Environmental geology; Geochemistry; Geophysics; Gold; Paleomagnetism; ... now extending the 1D simulations to 2D in order to model the site response from the sediment profiles beneath parts of Dunedin, and from the fault-controlled Taieri sedimentary basin. The Alpine fault is the Pacific-Australian plate boundary in the South Island of New Zealand. But if it happened again, given the population and buildings in the area, we wouldn't be so lucky. Your opinions are important to us. 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. The Canterbury Plains could suffer more damage in an Alpine Fault quake than some areas closer to the fault, say researchers - and it is not alone. "One of the real challenges with the Alpine Fault—because it is so bush-covered—is actually finding sites that have been cleared and therefore can be studied," said Langridge. This active transform fault ruptures in a large earthquake every 291 ± 23 years, most recently in 1717. Prof Davies is in the United Kingdom on sabbatical at present so could not be reached for comment on Monday's earthquake and its impact on the Alpine Fault. 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. The Alpine Fault is a big feature of South Island geography and seismic activity. Hear from leading Alpine Fault scientists about the likely impacts of an Alpine Fault earthquake in your area and how we can be better prepared for such an event. This fault has ruptured four times in the past 900 years, each time producing an earthquake of about magnitude 8. Thank you for taking your time to send in your valued opinion to Science X editors. These effects are covered in other papers within this special issue. Therefore, almost all local trips and inter-district trips from these three districts will be cancelled. The Alpine Fault is sometimes compared with California's San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. Professor Waters said the Akatore Fault remained a bigger threat to Dunedin than the Alpine Fault, which runs the length of the South Island. "We do think that it's in a heightened phase of activity, and it's hard to say how long that will last. Just days after South Island residents were shaken awake by a 5.5 magnitude Alpine Fault quake, University of Otago earthquake expert Professor Mark Stirling warns there's a bigger threat to Dunedin. How many aftershocks have there been, and is this normal? Recent research (published in 2012) by GNS Science has extended our knowledge of the Alpine fault earthquake record back through the past 8000 years. or, by Seismological Society of America. Listen: Mike Puru talks with geologist Martha Savage about New Zealand's largest faultline. Langridge said researchers in California and New Zealand have a long history of earthquake science collaboration and are learning from each other about the treatment of active faults and fault segmentation for seismic hazard models. Your feedback will go directly to Science X editors. The fault is not explicitly … "The old Akatore earthquake would have been similar in magnitude to the 2016 Kaikoura quake, with tens of kilometres of rocky coast affected, and the old shore lifted out of the water, well beyond the reach of the waves," says Professor Dave Craw. The 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. The Alpine Fault has a high probability (estimated at 30%) of rupturing in the next 50 years. ... which occurred close to the central part of the Alpine … Do equations for groundwater flow refer to water density? The Akatore Fault is close (20km or less)," he says. This was "clearly devastating" for coastal species like kelp and shellfish, which were left literally high and dry. The Dr Caroline Orchiston from the Centre of Sustainability, University of Otago, outlines a new initiative called Project AF8, a multi-agency approach to response and resilience planning for a magnitude 8 earthquake in the South Island. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. Kirilova, Martina Atanasova. You can unsubscribe at any time and we'll never share your details to third parties. The information you enter will appear in your e-mail message and is not retained by Phys.org in any form. 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. Apart from any fair dealing for the purpose of private study or research, no 5(b)). "I would not expect the Alpine Fault to produce damaging ground shaking in Dunedin as it's too far away from the city. Only earthquakes with a magnitude of 6.0 or greater are listed, except for a few that had a moderate impact. Current work and … An Alpine Fault earthquake will be felt by every South Islander and likely many North Islanders, too. Dunedin’s earthquake hazard was higher than Auckland’s. Due to the Alpine fault earthquake, the two main highways connecting the east of the South Island to the west (SH7 and SH73) and most parts of SH6 will be completely blocked one day post-disaster causing three Districts (Buller, Westland, and Grey) on the west coast to be isolated (Fig. In order to prevent massive damage to Dunedin, Prof Stirling urges authorities to put in place effective hazard and risk communication plans to warn the public, and emergency management plans that deal with an Akatore Fault earthquake scenario. "The ancient Akatore uplift was big enough to eliminate entire populations of intertidal species," the researchers say. 5G and future 6G terahertz absorbed by water vapour = heating? "By comparison, the Kaikōura Earthquake in 2016 ruptured a total fault length of 200km in the space of about two minutes," said Holden. Has this earthquake had any impact on the Alpine Fault? We have currently located 63 aftershocks, with 16 being magnitude 3 and above, this is … Magnitude-8.0 or greater earthquakes were expected on the Alpine Fault approximately every 300 to 500 years. This means, the Alpine Fault is late in its seismic cycle … Radiocarbon dating places this earthquake between 1813 and 1848. This study investigates the potential for seismic seiches in Lake Tekapo, New Zealand, triggered by ground shaking from an Mw8.2 Alpine Fault earthquake.
