At this point the surfaces of the two plates making up the South Islands alpine fault meet. Project AF8 Steering Group chair Angus McKay says the next research focus is creating a more in depth plan of how to help those people who will be worse affected. This proposed model already published in Holden and Kaiser (2016) satisfies the conditions required by the source panel. The Alpine Fault runs 400km up the South Island, along the western edge of the Southern Alps. / Natural Hazards and Risks The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. www.resorgs.org.nz. Extreme peak velocities of 3.8m/s are modelled in the Haast region. Vivez l’expérience Alpine. Find a local Authorised Alpine Specialist Dealer in your area. (2002). The synthetic records show that ground motion accelerations in Greymouth and Hokitika are expected to exceed 20%g and 50%g respectively during an Alpine fault earthquake, while ground motions in Christchurch are expected to be moderate, with peak ground accelerations (PGAs) of 8%g expected from an Alpine event and 6%g from a Hope fault event. Earthquakes along the fault, and the associated earth movements, have formed the Southern Alps. 1 / 5. These four short videos explain why we are taking the Alpine Fault so seriously and help you understand how you can be prepared for the disruption to normal life that a severe earthquake will cause. L’Alpine A110S offre une expérience de conduite intensément Alpine. The star represents the earthquake hypocentre. A new model has simulated the disruption a major Alpine Fault earthquake would have on the South Island's transport network - cutting off the West Coast for at least a week. The last time was in 1717. AF8 Alpine Fault modelling. Copyright © 2020 MediaWorks TV - All Rights Reserved, By subscribing you agree to our Terms of Access and Privacy Policy. We have computed broadband synthetic seismograms in Christchurch for a large possible Alpine fault earthquake. Both earthquakes were less than 50 km from the Christchurch central business area and had a magnitude that is much smaller than that expected from the Alpine Fault (Mw=8.2) and that is similar to a potential Hope Fault event (Mw7+). Configurez votre Alpine selon vos préférences en sélectionnant parmi l'ensemble des couleurs, équipements et accessoires proposés. The source model is 500 km long by 12 km wide with a maximum slip of 15 m half-way along the fault. / Our Science Note: far-field results are to be taken with caution due to the regional model and approach employed in this particular calculation of ground motion. It shows a rupture starting at the southern end of the Southern Alps and moving north toward Wellington. the alpine fault along the west coast of new zealand. 2 Frictional properties and characteristic length for earthquake nucleation and hydraulic diffusion. Based on general equilibrium theory adapted for business disruption response and equilibrium-seeking dynamics. / Alpine Fault and Hope Fault modelling. (2000) and Mai et al. Participer à nos événements. Home She says the more people prepare for such an event the easier life will be after it happens. We subsequently superimposed the effects of soft soil condition on the modelled ground motions. Plongez dans l’univers Alpine au sein de nos centres Alpine RRG. The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island and forms the boundary between the Pacific Plate and the Indo-Australian Plate. For each asperity, records from a small or moderate earthquake were used as proxies for the Green’s functions. AF8 [Alpine Fault magnitude 8] is a collaborative effort to save lives by planning and preparing a coordinated response across the South Island after a severe earthquake on the Alpine Fault. A 400 km rupture of the fault is expected to happen within our lifetime, which will have a broad impact on much of the South Island's critical infrastructure, Project AF8 lead scientist Dr Caroline Orchiston says. Lack of large earthquakes in the instrumental record enlarges uncertainty of the recurrence time; the recurrence of large earthquakes is generally determined by extrapolation according to a magnitude-frequency relation. The Alpine Fault is called a strike slip or transform fault. This proposed model already published in Holden and Kaiser (2016) satisfies the conditions required by the source panel. Such simulations can provide very useful alternative estimates of possible ground motions from large faults for major population centres. Consequential severe damage to lifelines, including the main transportation corridors, is also predicted. In this study, instead of using GMPE, we carry out synthetic broadband simulations to derive synthetic strong-motion records. Figure 14 The NS component of the synthetic Alpine fault rock site acceleration time history in (a), and soil surface acceleration time history in (b). Découvrez notre réseau et trouvez le Centre Alpine le plus proche de chez vous Austria - Österreich; Belgium - Belgique. The preliminary estimates for peak horizontal acceleration are less than 4% g. These results are reasonably consistent with recorded values from recent large earthquakes (Mw > 7) and distances of 150 km+. - fault line photos et images de collection. We distributed asperities where large surface fault displacements have been inferred from paleoseismic studies. In this preliminary study, we chose conservative values for all source parameters based on our current understanding of large crustal earthquake source mechanics. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. Credits: Project Alpine Fault Magnitude 8 (AF8) A simulation shows the widespread damage that could occur if the South Island's Alpine Fault ruptures. / Ground motion simulations As suggested by the source panel, it ruptures unilaterally from south to north with a rupture velocity of 2km/s. 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 Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. In general the response spectra from the simulations exceed the spectra derived from GMPE except for spectral periods between 0.5 and 1.2 seconds.

In general the response spectra from the simulations exceed the spectra derived from GMPE except for spectral periods between 0.5 and 1.2 seconds. ALPINE . The Alpine Fault connects two "subduction" margins where the ocean floor descends into the Earth's mantle. Smile Machines. Dealer Locator. The simulation is part of a series of videos created by Project AF8 so people can better understand and be prepared for such a event. The fault line along the South Island ruptures roughly every 300 years. In the simulation, the inset in (C) shows the fault geometry and injection. Approximate rupture dates are 1717AD, 1620 AD, 1450 AD, and 1100 AD. Milford Sound will be ruined by an earthquake on the Alpine Fault. The Alpine Fault. 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. This high PGA is likely due not only to non-linear soil response not accounted for in this study but also to the presence of a modelled asperity nearby and to strong directivity effects, neither of which are accounted for in current GMPE modelling for New Zealand. The duration of shaking is expected to last over 3 minutes for an Alpine fault earthquake and at least 20 seconds for a Hope fault earthquake. “Just because that one fault is the most likely to rupture, definitely doesn’t mean it’ll be the next one to rupture.” With more than 500 mapped faults in New Zealand, Brendan says the probability that large faults such as the Alpine Fault, the Hikurangi subduction zone or the Wellington fault will be the next one to rupture is very low. The New Zealand Journal of Geology and Geophysics has recently dedicated an entire issue to the South Island's Alpine Fault, which is now overdue a massive quake. Flagship 5 – Pathways to Resilience. Software Updates. However, most of the motion on the fault is strike-slip, with the Tasman district and West Coast moving North and … However the modelled PGA from an Alpine Fault event in Hokitika is 59%g, twice the level expected from a GMPE for a PGA of 27%g. Découvrir Rencontrez nos conseillers Alpine RRG Découvrir mon centre Alpine RRG « J’ai choisi le nom Alpine car cet adjectif représente pour moi le plaisir de conduire sur les routes de montagne » Jean Rédélé, fondateur de la marque Alpine. Download high-res image; Open in new tab; Download Powerpoint; Fig. Response spectra are computed from the synthetic ground motions, and are compared to those estimated from the New Zealand GMPE. Large accelerations are generated from localized asperities while the ground motions resulting from the rest of the fault rupture area are negligible. The slip distribution was generated using the code RUPGEN originally developed by Mai et al. Peak horizontal ground velocities (m/s) over the South Island for an Alpine Fault rupture scenario. The synthetic broadband strong-motion records are produced for both a possible large Alpine Fault earthquake (Mw8.2) and a large Hope Fault earthquake (Mw7.1) at sites in a number of selected population centres that may be strongly affected. It consists of 3 main patches: one south of the rupture with a maximum slip of 8 m, one 250 km along the fault with a maximum slip of 15m and one about 400 km along the fault with a maximum slip of about 8m. At present, the response spectra from a great scenario earthquake from the Alpine fault can only be estimated from ground-motion prediction equations (GMPEs) based on local and overseas earthquake records. The Alpine fault, one of the major fault systems in New Zealand, extends all through west coast with a high possibility of a rupture in the next 50 years, meaning that the next large earthquake on the Alpine Fault is likely to occur within our, or our children’s, lifetime. (2000) and Mai et al. Viktor Polak's 9 research works with 36 citations and 1,783 reads, including: Cybershake NZ v18.5: New Zealand simulation-based probabilistic seismic hazard analysis A major problem of all GMPEs, including even the latest GMPEs from the next generation attenuation (NGA), for example, Abrahamson and Silva (2008), is their very large variability in ground motion predictions for large and great earthquakes.
