The Alpine Fault that corresponds to the line of the Southern Alps has separated the basement rocks ... New Zealand is at risk from tsunamis that are generated from both local and international faults. An iso-seismal map is used to determine the hazard for a particular location in the seismic design standard that engineers use. Stresses in the Earth’s crust along the country’s plate boundary have caused it to break into fragments that move against each other along fault lines. The Taupo Volcanic Zone also has many active faults associated with rifting and extension of the crust in the area. This is a very distinct feature along most of its length because of the Southern Alps that have been uplifted along its eastern side, making it clearly visible from space. Locally the faults along the North Island's east coast provide … Subduction zones are a type of fault and are responsible for the largest and most powerful earthquakes and tsunamis in the world, such as Sumatra 2004, Chile 2010, and Japan 2011. In the South Island, the Marlborough Fault System is another series of major parallel faults.These join together further south to form the Alpine Fault which carries most of the total plate boundary strain. GNS Science is a New Zealand Crown Research Institute. There are aroung 20,000 earthquakes annually, most are small, but the country gets its share of big quakes too. There are major fault lines running the length of New Zealand. Our map of New Zealand’s tectonic plates shows the relative movement between the Pacific and Australian Plates in ... Waikato Regional Council has produced a ‘regional Ground Shaking Risk Zones and Active Fault Lines’ map showing active faults in the region and the extent of the Taupo Volcanic Zone and is used in our Waikato region Lifelines Study. Try our Google Map of New Zealand with Search →. New Zealand an ideal place to study plate boundary kinematics using active fault data. Scientists have revealed new insights into what's piling pressure on New Zealand's big-risk Alpine Fault – and whether the past decade's quakes have added to its squeeze. To simplify the design and construction of light timber-framed and smaller concrete block masonry buildings in these regions, New Zealand’s construction standards divide the country into four earthquake risk zones. Kaikoura, the New Zealand tourist town cut off by 7.5 magnitude earthquake Published: 14 Nov 2016 'Like living on a waking dragon': New Zealanders count cost of earthquake Earthquakes along the fault, and the associated earth movements, have formed the Southern Alps. These detailed maps of New Zealand show some of the major fault lines in the North and South Islands. The range has a sharp edge on its western front, as is clearly seen in satellite images. The massive 7.8 Kaikoura earthquake in 2016 only claimed two lives due to being located mostly in a rural area and striking in the early hours of the morning. From Wikipedia, the free encyclopedia 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. volcanoes are plotted on a world map they reveal that New Zealand is part of a huge ‘ring’ of volcanic and earthquake activity. The North Island Fault System is a major plate boundary feature in the North Island, under constant stress from movement between the Pacific and Australian plates. The Wellington Fault location review identified 665 properties within the new recommended fault rupture hazard zone (some properties straddle both the likely fault rupture zone and the recommended fault rupture hazard zone or buffer zone). NEW Zealand could be in store for a devastating earthquake in the coming years with two fault zones set to collide. When you have eliminated the JavaScript , whatever remains must be an empty page. Earthquakes ranked by magnitude on the Richter scale. Compression is uplifting the mountains at a rate of 2 mm per year, and this has been going on for the past 10 million year. This assessment was based on the known effects of the 1855 Wellington /Wairarapa earthquake, plus the high visibility of major fault lines. Click the map to see a volcanic map of New Zealand.

When I was young, and indeed until recently, the conventional wisdom was that Wellington was the region of New Zealand with the highest earthquake risk. The Hikurangi Trench, also called the Hikurangi Trough, is an oceanic trench in the bed of the Pacific Ocean off the east coast of the North Island of New Zealand, lying between the southern end of the Cook Strait and the Chatham Rise. However, there are still many other relatively minor faults across the South Island, which rupture less frequently, such as those which have caused the Canterbury and Christchurch earthquakes. The new information has been added to Council’s GIS maps as a Fault Hazard Corridor, but the existing Fault Hazard Overlay in the NRMP has not changed yet. Some smaller faultlines can also be seen on the map - … 3. It is owned by the Government and carries out research for the benefit of New Zealand. Earthquake Fault Lines Nz - Fault Line New Zealand Volcanoes Map : Is there any possibility of nz splitting between greymouth & christchurch in the future?. Such a sequence of earthquakes occurring on different faults in such a short time-frame has not been witnessed before in New Zealand. The North Island Fault System runs in a line from the Bay of Plenty to the Wellington coast and is responsible for creating the Kaweka, Ruahine, Tararua and Rimutaka mountain ranges. The deadliest earthquake in New Zealand was the 1931 Hawke's Bay earthquake, (Napier earthquake) which claimed 256 lives followed by the June 2011 Christchurch earthquake which claimed 181 lives.

Enable JavaScript to see Google Maps. What is also highlighted in this picture is that the North Island System actually separates the main Indo-Australian Plate (in this diagram more simply called the Australian Plate) from a ‘rootless fragment’ of this same plate. The devastating Kaikura earthquake in … There are major fault lines running the length of New Zealand. Check that the broad indication of hazard from the maps is correct for a particular site. Watch our video about New Zealand faults and earthquakes here. This section lets visitors see quakes that have occurred anywhere in the world in the last week. Running in a continuous line from the Bay of Plenty southwards to the Wellington coast, this system has pushed up a line of mountain ranges including the Kawekas, Ruahines, Tararuas and Rimutakas. The first map (above) shows the three major fault systems in New Zealand: the North Island System, the Marlborough System and the Alpine Fault. The plate boundaries around the Pacific Ocean are the most active in the world and this area is often referred to as the ‘Ring of Fire’. NEW Zealand could face an apocalyptic earthquake and tsunami after a 2016 earthquake awoke a fault line that was thought to be dormant. Geologists from New Zealand drew up the tectonic and bathymetric maps of the Earth's eighth continent — which spans some 1,930,511 square miles. Of these 665 properties, there were 244 more properties than currently identified on the planning maps. It is the southward continuation of the much deeper Kermadec Trench. It is considered to be at high risk of producing a major earthquake in the next 50 years. 2. New Zealanders have long known that their mountainous country is acutely vulnerable to tectonic movements. 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. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. The USGS has many maps of live earthquake data. New Zealand Earthquake Faults. / Earthquakes The eastern coast of New Zealand is most at risk as the Pacific Ocean is more tectonically active than the Tasman Sea. Author & photographer: David Johnson (Virtual New Zealand). New Zealand sits on the boundary between the Australian and Pacific tectonic plates, and is being pulled apart almost imperceptibly as the plates shift. Is there any possibility of nz splitting between greymouth & christchurch in the future? Many of the larger faults are oblique-slip faults, which can cause a combination of horizontal and vertical movement. / Learning Notes on earthquake hazard mitigation measures 1.
