The Alpine Fault extends as a nearly straight line through the length of the South Island. Background Readings for The Alpine Fault. 24 May 2018. Because of this, there are a limited number of places where scientists can have easy access to study it in detail. Listen duration 4 ′ : 05 ″ Add to playlist Playlist. The research, published today in the leading journal Science , presents a revised timeline of earthquakes occurring on the alpine faultline dating back 8,000 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. The Alpine Fault is known to rupture in magnitude 8 earthquakes approximately every 300 years. Videos. PHOTO: PROJECTAF8.CO.NZ “What we know about the Alpine Fault is that it tends to produce big earthquakes, roughly every 300 years,” Dr Orchiston said. LEARN ABOUT IT. From the LEARNZ Alpine Fault online field trip at… But new evidence of a 19th century earthquake indicates that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events. The Alpine Fault trace is a low scarp cutting across calf paddock , J.Thomson / GNS.Science. AF8 [Alpine Fault magnitude 8] is again teaming up with leading earthquake scientists and Civil Defence Emergency Management (CDEM) Groups … Alpine Fault. The South Island Alpine Fault Earthquake Response (SAFER) Framework is the result of two years of effort by AF8, a collaboration between all the South Island’s Civil Defence Emergency Management Groups, scientists and partner agencies. Another Alpine Fault earthquake uplifts the scarp, and a new earthquake debris layer is deposited, adding another record to the fault rupture history. The Alpine Fault runs for about 600km along the west of the Southern Alps. 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. It runs for 650 kilometres along the spine of … The borehole that was drilled will be used for further research, including to monitor changes over the years. For much of its length, it runs through steep, inaccessible, and bush-clad country. The Alpine Fault is sometimes compared with California’s San Andreas Fault, being another fast-moving strike slip fault near a plate boundary. Fault line . . Download. A wall has been built across the fault scarp to check for movement. Numerous experts say it will be the largest natural disaster of … WELLINGTON (DPA) - A 5.5-magnitude quake rocked New Zealand's Alpine Fault early Sunday (June 9), triggering a warning by the country's earthquake monitoring service..
