allow individual streets to be identified in the map. Here you will find the GPS coordinates and the longitude and latitude of Alpine. The red line on this map shows our plate boundary (see Module 2). 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. 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. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. Figure 4 Map of the Alpine Fault in West Coast region and the data sources used in this mapping study (shown by colour). Read more. Latitude of Alpine: 32.8350521: Longitude of Alpine-116.7664109: Rate our service for the coordinates of Alpine. The Hope Fault is an active dextral (right lateral) strike-slip fault in the northeastern part of South Island, New Zealand.It forms part of the Marlborough Fault System, which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian Plate and Pacific Plate, from the transform Alpine Fault to the Hikurangi Trench subduction zone. Fault ruptures (earthquakes) have displaced river terraces that cross the fault. ©NASA The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. Pākihi Supergoup: 5 million years ago – present. ALPINE FAULT: "An earthquake on the Alpine Fault in the near future would not be a big surprise." The Australian plate is sliding horizontally towards the north-east, at the same time as the Pacific plate is pushing up, forming the … Most of the movement along the fault is horizontal (sideways), but there is also a vertical component. Reverse and … Turning inland, the Alpine Fault runs to a point near the Lewis Pass, travels northwards then frays into four main faults that extend to the east coast. It is worth looking at the wall to see how it has stood the test of time. J.Thomson / GNS.Science, The surface trace of the Alpine Fault and an experimental concrete wall. Elizabeth, our tour guide, was very knowledgeable and enthusiastic showing off this area of NZ and explaining how the tectonic plates work. Several major faults run alongside and within this system, including the Wellington Fault. The length of the rupture will be … The Alpine Fault marks the boundary of the Pacific and Australian Plates. 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. Skip to Main Content. Movement along this fault has uplifted the Southern Alps and helped shape the South Island landscape we know today. KML (Google Earth-type) files and GIS shape files are also available for download from the site. Contour line interval is 0.5 m. This is a classic exposure of the Alpine Fault. The alpine fault earthquake will alter tectonic stress distribution, and other faultlines may rupture in the days or years following it. The Alpine Fault marks the boundary of the Pacific and Australian Plates. Most of the movement along the fault is horizontal (sideways), but there is also a vertical component. The Alpine Fault is a geological fault, known as a right-lateral strike-slip fault, that runs almost the entire length of New Zealand's South Island. © GNS Science 2017, version 3.2.4.197 created 20190802-1555, Alpine Fault at Gaunt Creek, J.Thomson / GNS Science, Deep Fault Drilling Project Observatory container, J.Thomson / GNS Science, Information panel at Gaunt Creek, J.Thomson / GNS Science, The top of the Australian Plate seen from above Gaunt Creek, J.Thomson / GNS Science, Pointing out the Alpine Fault at Gaunt Creek, J.Thomson / GNS Science, Alpine Fault cataclasite at Gaunt Creek, J.Thomson / GNS Science, Pointing at the fault. A reverse fault (if steeply dipping) or thrust fault (if shallowly dipping) is a fault where the fault plane dips toward the upthrown block. Transform faults are also referred to as "conservative" plate boundaries, inasmuch as lithosphere is neither created nor destroyed. The uplift to the southeast of the fault is due to an element of convergence between … Athy 19 contributions 4 helpful votes. The Alpine Fault is responsible for forming the Southern Alps mountain range, which has been pushed up on the Pacific Plate side of the boundary. Access is across private farmland, just south of Whataroa. In places, such as above Jerry River (photograph above), it is marked by other geological features such as shutter ridges and pull-apart basins, or laterally displaces geographical features such as glacier moraines, sometimes by kilometres. QMAP mapping data is predominant at the northeast and southwest ends of the fault, while Otago University mapping is the predominant source from Hokitika to Haast. … Because the Alpine fault begins so cleanly, Furlong believes it can tell us something about strike-slip faults in general. The Alpine Fault. At its northern end it divides into several branches that are known as the Marlborough Fault System. Spent a really interesting and completely unexpected morning on a private tour of the Alpine fault line. High risk faults in New Zealand include the Alpine Fault, Wairararapa Fault, Wellington Fault, and Napier Fault. There are also several important faults offshore to the east of Marlborough. Most of New Zealand's major faults are similar in this respect. In other words, movement will occur suddenly during an earthquake, rather than gradually. The Alpine Fault is the boundary between the Pacific crustal plate and the Australian plate. The Pacific Plate and Indo-Australian Plate boundary forms the Macquarie Fault Zone in the Puysegur Trench off the southwestern corner of the South Island and comes onshore as the Alpine Fault just north of Milford Sound. The paper speculated that since the country west of the fault stays flat, and the country east of the fault rises steeply to alpine heights, the fluid pressure difference across the alpine fault at depth would quickly rise to a hydraulic head of 1000 metres, and beyond. The Alpine Fault is clearly visible from space, running along the western edge of the Southern Alps from the southwestern coast towards the northeastern corner of the South Island. 0/5. The bus trip there and back also good fun. 6. slip vector is oriented approximately 20 to the trace of the fault, resulting in components of 35.5 mm/yr parallel and 10 mm/yr perpendicular to the Alpine Fault. QMAP mapping data is predominant at the northeast and southwest ends of the fault, while Otago University mapping is the predominant source from Hokitika to Haast. How often does the Alpine Fault rupture? There is an interactive map application to view the faults online and a separate database search function. It runs as a single structure for over 500 km. You can pick out the line of the Alpine Fault on this satellite image of the South Island. Share. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. Contact http://alpinefaulttours.co.nz/ (or phone 0800556244) to book a trip that will depart from Whataroa.
