Based on general equilibrium theory adapted for business disruption response and equilibrium-seeking dynamics. Just-released videos have shown what would happen in the event of a major quake along the South Island's big-risk Alpine Fault. It’s the "on-land" boundary of the Pacific and Australian Plates. The source model is 500 km long by 12 km wide with a maximum slip of 15 m half-way along the fault. (2000) and Mai et al. 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. The star represents the earthquake hypocentre. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. 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). The last time was in 1717. Calculations for synthetic seismograms are based on a validated algorithm for large crustal earthquakes.

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. This fault has ruptured four times in the past 900 years, each time producing an earthquake of about magnitude 8. The fault line along the South Island ruptures roughly every 300 years. Earthquakes along the fault, and the associated earth movements, have formed the Southern Alps. Extreme peak velocities of 3.8m/s are modelled in the Haast region. Everything not tied to the ground will move. Video simulation shows 12m-high tsunami battering New Zealand coast 5 Mar, 2018 10:31 PM 3 minutes to read Animation showing the tsunami threat posed by … She says the more people prepare for such an event the easier life will be after it happens. 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+. Participer à nos événements. / Our Science / Alpine Fault and Hope Fault modelling. Synthetic ground motions from the broadband simulations are generally consistent with PGAs estimated from GMPEs. 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. 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. Large accelerations are generated from localized asperities while the ground motions resulting from the rest of the fault rupture area are negligible. 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. 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. 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. Search. However, most of the motion on the fault is strike-slip, with the Tasman district and West Coast moving North and … 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. Austria - Österreich; Belgium - Belgique. the alpine fault along the west coast of new zealand. 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. 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. We have computed broadband synthetic seismograms in Christchurch for a large possible Alpine 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. Recent advances in earthquake mechanics allow us to compute seismograms for realistic earthquake scenarios, at specific locations, and with specific site conditions. Response spectra are computed from the synthetic ground motions, and are compared to those estimated from the New Zealand GMPE. (2000) and Mai et al. Bienvenue sur le site officiel Alpine Cars. Alpine Fault heterogeneous slip model scenario employing RUPGEN toolkit developed by Mai et al. 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 runs 400km up the South Island, along the western edge of the Southern Alps. As suggested by the source panel, it ruptures unilaterally from south to north with a rupture velocity of 2km/s. Ensure your Alpine product is covered by our limited warranty* Register. Flagship 5 – Pathways to Resilience. 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 simulation shows the widespread damage that could occur if the South Island's Alpine Fault ruptures. Register Warranty. Plongez dans l’univers Alpine au sein de nos centres Alpine RRG. The model is 500 by 12 km long, striking 52 degrees, dipping 45 degrees and with a rake angle of 173 degrees. 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. 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+). 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.

Milford Sound will be ruined by an earthquake on the Alpine Fault. Cross-Flagship Project: Alpine Fault. Future Alpine A110 Cabriolet (2019) – Pour espérer concurrencer Porsche, Alpine se doit de développer sa gamme.Ce devrait être chose faite avec l’arrivée prochaine d’un modèle découvrable. 2 Frictional properties and characteristic length for earthquake nucleation and hydraulic diffusion. By using conservative parameters, we are attempting to model maximum possible ground shaking intensity. As such, they account for path effects incurred during propagation of the waves from the earthquake to the receiver site. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. Such a duration is comparable to the duration observed in Christchurch from the 2010 Mw 7.1 Darfield earthquake. Download high-res image; Open in new tab; Download Powerpoint; Fig. The massive Alpine Fault is due for another big earthquake and scientists have been drawing up a scenario of what the devastation would look like. This proposed model already published in Holden and Kaiser (2016) satisfies the conditions required by the source panel. Read more. We distributed asperities where large surface fault displacements have been inferred from paleoseismic studies. What is MERIT? 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. Important information about buying Alpine products online. // The Alpine configurator can display the local prices for all the countries where the A110 are sold. In this study, instead of using GMPE, we carry out synthetic broadband simulations to derive synthetic strong-motion records. Peak horizontal ground velocities (m/s) over the South Island for an Alpine Fault rupture scenario. 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. 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 earthquake. It shows a rupture starting at the southern end of the Southern Alps and moving north toward Wellington. Famous Awatere active fault line on north west side of Awatere Valley, Branch of great alpine fault, Aerial, New Zealand. Pure. Réservez votre essai de l’A110. 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. (2002). Computer simulation model for assessing the economic impacts of disruption events. The model is 500 by 12 km long, striking 52 degrees, dipping 45 degrees and with a rake angle of 173 degrees. 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. Smile Machines. The Alpine Fault ruptures roughly every 300 years. Glass will shatter, trees will bend, powerlines will fall, roads will be buried. 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. In this preliminary study, we chose conservative values for all source parameters based on our current understanding of large crustal earthquake source mechanics. 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. This proposed model already published in Holden and Kaiser (2016) satisfies the conditions required by the source panel. Site effects for soft ground conditions were also added to account for possible amplification of ground shaking by soil layers in Christchurch. Such simulations can provide very useful alternative estimates of possible ground motions from large faults for major population centres. Large earthquakes (magnitude ≥ 7.0) are rare, especially along slow-slipping plate boundaries.

We subsequently superimposed the effects of soft soil condition on the modelled ground motions. 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. www.resorgs.org.nz. We computed the ground motion for generic rock sites in Christchurch. Synthetic ground motions are used as a forcing boundary to drive lake water motions by further developing a tsunami simulation model—COMCOT—and coupling it with earthquake simulation model outputs. Recent research (published … simulations can provide very useful alternative estimates of possible ground motions from large faults for major population centres. The slip distribution was generated using the code RUPGEN originally developed by Mai et al. At this point the surfaces of the two plates making up the South Islands alpine fault meet.

Consequential severe damage to lifelines, including the main transportation corridors, is also predicted. ALPINE . Approximate rupture dates are 1717AD, 1620 AD, 1450 AD, and 1100 AD. In the simulation, the inset in (C) shows the fault geometry and injection. For each asperity, records from a small or moderate earthquake were used as proxies for the Green’s functions. The Alpine Fault connects two "subduction" margins where the ocean floor descends into the Earth's mantle. The Australian plate is sliding horizontally towards the north-east, at the same time as the Pacific plate is pushing up, forming the Southern Alps. 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. Find a local Authorised Alpine Specialist Dealer in your area. The source is also characterized by tapered slip down to zero meter up to the surface and down to the depth of 12km. / Earthquakes 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.
