Movement along this fault has uplifted the Southern Alps and caused large earthquakes. Work during the 1990s has established that the Alpine Fault is a major source of potential seismic hazard and incorporation of data from the fault into seismic hazard maps has greatly changed the perception of earthquake hazard in the South Island. Things to do near Alpine Fault Tours. Awesome experience. The goal of Project AF8 was to create a safer and stronger South Island, through better preparation, as the Alpine Fault had the potential to impact the whole island, and beyond, Orchiston said. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. The rapid uplift also means that faulted rock from deep down has been brought to the surface, and can be studied by scientists. The scenarios were designed and developed as part of Project AF8, or Alpine Fault Magnitude 8, a partnership of all the Emergency Management Groups in the South Island. "The intensity of course depends on the type of ground you're standing on and how far away you are from the Alpine Fault. Brilliant tour, unique occurance, highly informative, very friendly guides.

The Alpine Fault was inferred to continue south-west from Lake McKerrow along the northern Fiord-land Coast (see also Grindley, 1958). The Alpine Fault marks the boundary of the Pacific and Australian Plates. The last Alpine Fault quake, which occurred in 1717, measured an approximate magnitude 8.1 - making it about three times stronger than the Kaikoura quake of 2016. "For those of you who felt the earthquake in Kaikōura, those many minutes of shaking, this [the Alpine Fault earthquake] will feel similar for you in Marlborough.".

Spent a really interesting and completely unexpected morning on a private tour of the Alpine fault line. As with many natural systems, there was a spread of intervals with the longest being about 510 years and the shortest about 140 years. 8.2b). Since September, an international team of scientists has b een based on the West Coast drilling into the Alpine Fault - the on-land boundary between the Pacific and Australian tectonic plates. 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. Most New Zealanders alive today will still be alive when the Alpine Fault rips in a magnitude-8 earthquake, leading scientists say. 20 years earlier, they had been in tourism in Fiordland NZ, taking international visitors on overnight cruises to see the fiords - and this will become relevant in a moment. There is no way of predicting exactly when an earthquake will occur. How often does the Alpine Fault rupture?

From there, the Alpine Fault runs along the western edge of the Southern Alps, before splitting into a set of smaller dextral strike-slip faults north of Arthur's Pass , known as the Marlborough Fault System . 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. Seismologists regarded the past 30 to 40 years as a period of quiescence in New Zealand as there had been no big on-land earthquakes. Recent research by GNS Science has extended our knowledge of the Alpine fault earthquake record back through the past 8,000 years. The study aims to inform locals and tourists of the significant risk to the area should the Alpine faultline go off. The investigation found the mean interval between large earthquakes on the fault is 330 years and two thirds of the intervals were between 260 and 400 years. "I don't think the Alpine Fault will cause uplift in Marlborough; the land going up like it did in the Kaikōura earthquake," van Dissen said. 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.

We've known about the Alpine Fault for around 80 years. The Alpine Fault is a geological fault that runs entirely through New Zealand's South Island. Affect a much larger area than earthquakes such as the Darfield earthquake. Because of the way earthquake magnitude is measured this means that a magnitude 8 earthquake releases about 30 times more energy than a magnitude 7. Co-ordinated Planning and Partnerships Pay Off.

Alpine orogeny, mountain-building event that affected a broad segment of southern Europe and the Mediterranean region during the Paleogene and Neogene periods (65.5 million to 2.6 million years ago).The Alpine orogeny produced intense metamorphism of preexisting rocks, crumpling of rock strata, and uplift accompanied by both normal and thrust faulting. Even the trees that have survived an earthquake will bear the scars of the shaking, in the form of periods of poor growth recorded in their rings. Elisabeth, your guide, has a good knowledge of the Alpine Fault, and to be able to straddle 2 tectonic plates was a real moment to remember.

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. Most New Zealanders alive today will still be alive when the Alpine Fault rips in … "What it [the figures] also tells us is that these events have been popping off through time and there's really no reason for them to stop happening.". The development of the basins of southwest New Zealand is related to the behaviour of the Fiordland microplate, a rigid block of continental crust located between the Moonlight and Alpine fault systems. 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. Milford Sound is the most likely epicentre for a magnitude-8 earthquake on the Alpine Fault. Earthquake epicentres indicate that the arc defines the position of the fault just off Fiordland's outer coast and then to near the north end of Puysegur Trench at 46.9° S, 165.25° E. Along the fault vertically to a depth of 10 km the Fiordland rocks are 0.6 Mg/m 3 denser than those to the northwest. Image: NASA.

New Zealand, Kā Roimata o Hine Hukatere - Franz Josef Glacier, Likely rupture along a larger area of the fault (several hundreds of kilometres), It will last longer (hundreds of seconds rather than tens of seconds). The 7.8-magnitude Kaikōura earthquake ripped road and rail apart. The trenches, each of about 20m-long will allow the geologists to take photos and make detailed drawings of the recently deposited strata to a depth of 2m. "The Alpine Fault is a spectacular fault, it's more than 800 kilometres long at its full extent," Orchiston said.
