See all hours. Unless otherwise agreed in writing by GNS Science, GNS Science accepts … The Alpine Fault is called a strike slip or transform fault. The Alpine Fault forms a "transform" boundary between the Pacific Plate and Indo-Australian Plate. Tours are 2.5 hours, and require walking. New Zealand is part of Zealandia, a microcontinent nearly half the size of Australia that broke away from the Gondwanan supercontinent about 83 million years ago. It has been suggested that the surface rupture formed by this event helped influence Charles Lyell to link earthquakes with rapid movement on faults. In Wellington, close to the epicenter, shaking lasted for at least 50 seconds. This is unlike the North Island boundary, where a subduction zone is under water off the east coast. The fault plane is usually vertical and can be horizontal. It forms part of the North Island Fault System, which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian Plate and Pacific Plate. The Marlborough Fault System is a set of four large dextral strike-slip faults and other related structures in the northern part of South Island, New Zealand, which transfer displacement between the mainly transform plate boundary of the Alpine fault and the mainly destructive boundary of the Kermadec Trench, and together form the boundary between the Australian and Pacific Plates. 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. Between 25 and 12 million years ago the movement on the proto-Alpine Fault was exclusively strike-slip. Originally reported as magnitude 6.6 on the Richter Scale, the earthquake was later downgraded to a magnitude of 6.2. It was during this time that the cyclicity of the Alpine Fault earthquakes and meaning of the increase in metamorphic grade towards the fault was discovered and refined. That's before satellite photographs or plate tectonics. Read more. Berryman et al., 2012). Le temps de l'apprécier. Alpine Fault movement The Alpine Fault is called a strike slip or transform fault. [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. Depuis le mois de juin, Alpine a diligenté trois nouvelles campagnes de rappel afin de corriger un potentiel défaut de fabrication sur l'Alpine A110. A transform (oceanic) or strike-slip (continental) fault is one where the relative motion is horizontal. [Chapter Break] After their ground­breaking paper on the Alpine Fault, Willett was posted to Invercargill and Wellman to another war­time project at d’Urville Island. Le cisaillement sud armoricain [2] dans la partie sud du Massif armoricain. [15] In 2017, GNS researchers revised the figures after they combined updated Hokuri site records with a thousand-year record from another site 20 km away at John O'Groats River to produce a record of 27 major earthquake events during the 8000-year period. The Māori arrived in New Zealand c.1300 but never reached a high population density in the colder South Island. The Hope Fault is an active dextral strike-slip fault in the northeastern part of South Island, New Zealand. Preparing for an Alpine Fault earthquake. Lateral displacements of this magnitude could not be explained by pre-plate tectonics geology and his ideas were not initially widely accepted until 1956. [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. The Alpine fault is the Pacific-Australian plate boundary in the South Island of New Zealand. The name "Southern Alps" generally refers to the entire range, although separate names are given to many of the smaller ranges that form part of it. Type: Full-length Release date: November 11th, 2011 Catalog ID: N/A Label: Independent Format: CD Reviews: None yet Songs; Lineup; Reviews; Additional notes; 1. The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. Science and technology. JFAST gathered important data about the rupture mechanism and physical properties of the fault that caused the huge earthquake and tsunami which devastated much of northeast Japan. It forms part of the North Island Fault System, which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian Plate and Pacific Plate. A total of 1112 aftershocks were recorded, ranging between magnitudes 2.0 and 4.9 on the Richter Scale. Into the Night 05:10 Show lyrics (loading lyrics...) 2. 25 Reviews 1 Q&A. In this recording, Alpine fault drilling, part of Te Papa’s Science Express programme, hear about the deepest fault drilling ever done in New Zealand. She then worked as a research associate professor in geology and associate dean (international) in the Division of Sciences at the University of Otago. THE ALPINE FAULT ZONE For certain types of reports and certain structural problems, it is advisable to try to identify the Alpine Fault plane as accurately as possible and to fix its position in the field. This includes mylonites and the Alpine Schist, which increases in metamorphic grade towards the fault. The United States Geological Survey reported a magnitude of 6.0 Mw and a depth of 9 km (5.6 mi). 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.
