alpine fault type

Le cisaillement sud armoricain [2] dans la partie sud du Massif armoricain. Researchers are studying the Alpine Fault to investigate past earthquakes, mountain formation and the structure of the Earth’s crust. See this Interactive map of the Alpine Fault and links to a virtual field trip on the University of Otago Geology website. We show that stresses transferred to the mid-crust during an Alpine Fault type earthquake may exert a first-order effect on localization in underlying ductile crust. Unless otherwise agreed in writing by GNS Science, GNS Science accepts … Geologically, this is a high probability. [27] [28] One of the goals of the project was to use the deformed rocks from the fault zone to determine its resistance to stress. Whole forests that have grown back after an earthquake can be dated, too. The rock contains bands of melted rock that seeps into fractures. [16] A 2018 study says that a significant rupture in the Alpine Fault could lead to roads (particularly in or to the West Coast) being blocked for months, as with the 2016 Kaikoura earthquake, with problems in supplying towns and evacuating tourists. [32]. Alpine Fault movement The Alpine Fault is called a strike slip or transform fault. [10] So while earthquakes are an important part of Māori oral tradition, no stories have been passed down about South Island earthquakes. [5] The Alpine Fault is not a single structure but often splits into pure strike-slip and dip-slip components. The geology of New Zealand is noted for its volcanic activity, earthquakes and geothermal areas because of its position on the boundary of the Australian Plate and Pacific Plates. The Alpine Fault intersects the west coast of the South Island of New Zealand about four miles north of Dale Point at the entrance to Milford Sound; moraine 011 the west of the fault has beeili faulted against Fiordlancl Gneiss' on the east, A well defined fault trace was followed from the air from the south side of Open Now. A transform fault is a type of strike-slip fault at the boundary of two plates. She is one of the leaders of the Deep Fault Drilling Project of New Zealand's Alpine Fault, and was a research scientist on the Japan Trench Fast Drilling Project. Wellman became a Fellow of the Royal Society of New Zealand in 1954, and was awarded the Hector Memorial Medal and Prize in 1957 and the McKay Hammer Award in 1959. Hours Today: 9:30 AM - 6:00 PM . Scientists say that a similar earthquake could happen at any time as the interval since 1717 is longer than between the earlier events. The maximum perceived intensity was IX (Violent) on the Mercalli intensity scale' possibly reaching X (Extreme). The Alpine Fault runs for about 600km up the spine of the South Island, and is one of the world’s major geological features. Current research includes: Keith Machin, Teaching Fellow at the University of Canterbury, helped visiting Swiss scientists study the Alpine Fault. [25], The Deep Fault Drilling Project (DFDP) was an attempt in 2014 to retrieve rock and fluid samples and make geophysical measurements inside the Alpine Fault zone at depth. That's before satellite photographs or plate tectonics. There have been no major earthquakes on the main portion of it. This gave a mean recurrence rate of 291 years, plus or minus 23 years, down from the previously estimated rate of 329 years, plus or minus 26 years. The 2014 Eketahuna earthquake struck at 3:52 pm on 20 January, centred 15 km east of Eketahuna on the south-east of New Zealand's North Island. Snow on the mountains of the Pacific plate contrasts with the lower land of the Australian plate. 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.
