1929 Arthur's Pass Earthquake
The 1929 Arthur's Pass earthquake occurred at on 9 March. The sparsely settled region around Arthur's Pass of the Southern Alps shook for four minutes. Tremors continued almost continuously until midnight and sporadic strong aftershocks were felt for several days. The earthquake was measured at 7.1 on the Richter magnitude scale and the intensity of shaking in the epicentral region has been assessed from historical records as VIII (''Severe'') on the Modified Mercalli Scale. Intensities of VI (''Strong'') were observed in Christchurch and Westport. The earthquake occurred on the Poulter Fault, which was not identified and mapped until 2001. Tectonic setting New Zealand lies along the boundary between the Australian and Pacific plates. In the South Island most of the relative displacement between these plates is taken up along a single dextral (right lateral) strike-slip fault with a major reverse component, the Alpine Fault. In the North Island the displacement is mainly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NZST
Time in New Zealand is divided by law into two standard time zones. The main islands use New Zealand Standard Time (NZST), 12 hours in advance of Coordinated Universal Time (UTC) / military M (Mike), while the outlying Chatham Islands use Chatham Standard Time (CHAST), 12 hours 45 minutes in advance of UTC / military M^ (Mike-Three). During summer months – from the last Sunday in September until the first Sunday in April – daylight saving time is observed and clocks are advanced one hour. New Zealand Daylight Time (NZDT) is 13 hours ahead of UTC, and Chatham Daylight Time (CHADT) 13 hours 45 minutes ahead. New Zealand's associated states – the Cook Islands and Niue – and the dependent territory of Tokelau use several different time zones at their own discretion. History On 2 November 1868, New Zealand officially adopted a standard time to be observed nationally, and was the first country to do so, about fifteen years before any other. Chatham Island was 45 minutes ah ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board offi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquakes In New Zealand
This is a list of large earthquakes that have occurred in New Zealand. Only earthquakes with a magnitude of 6.0 or greater are listed, except for a few that had a moderate impact. Aftershocks are not included, unless they were of great significance or contributed to a death toll, such as the M 6.3 2011 Christchurch earthquake and the M 7.3 aftershock to the 1931 Hawke's Bay earthquake. Earthquakes occur frequently in New Zealand as the country is situated in the collision zone between the Indo-Australian and Pacific tectonic plates, part of the Pacific Basin Ring of Fire, where many earthquakes and volcanoes occur. Most events occur along the main ranges running from Fiordland in the southwest to East Cape in the northeast. This axis follows the boundary between the Indo-Australian and Pacific plates. Large earthquakes are less common along the central Alpine Fault, where the plates are not subducting and the forces are accommodated in different ways. The largest city wit ...

List Of Earthquakes In 1929
This is a list of earthquakes in 1929. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Several large events occurred this year with the main focus of the activity being in Alaska with 4 magnitude 7.0 + events. The deadliest earthquake struck Turkmenistan in May with 3,800 of the years 3,972 deaths in this event. A rare earthquake struck the north Atlantic Ocean in November with the deaths of 28 in Canada being caused by a tsunami. Indonesia was notably quiet this year. Overall By death toll * Note: At least 10 casualties By magnitude * Note: At least 7.0 magnitude Notable events January February March April May June July August September October November De ...

1929 Murchison Earthquake
The 1929 Murchison earthquake occurred at 10:17 am on 17 June. It struck the Murchison region of the South Island, with an estimated magnitude of 7.3, and was felt throughout New Zealand. There were 17 deaths, mostly as a result of landslides triggered by the earthquake. The rumbling sound of the earthquake was loud enough to be heard at New Plymouth, more than 250 km (155 mi) away. Tectonic setting New Zealand sits astride the boundary between the Indo-Australian Plate and the Pacific Plate. In the South Island most of the displacement is taken up on the Alpine Fault passing to the north onto a set of strike-slip faults, the Marlborough Fault System. The sense of displacement across the plate boundary is oblique and most of the faults have a reverse component of slip. Some of the resulting deformation is accommodated within the plates themselves away from the boundary. The 1929 Murchison earthquake occurred on the White Creek Fault, located in the Buller Gorge ...

Midland Line, New Zealand
The Midland line is a 212 km section of railway between Rolleston and Greymouth in the South Island of New Zealand. The line features five major bridges, five viaducts and 17 tunnels, the longest of which is the Otira tunnel. It is the route of the popular TranzAlpine passenger train. History Railway development in the South Island in the 1870s was concentrated on a main line linking the established centres of Christchurch, Timaru, Dunedin and Invercargill and light, easily constructed branch lines serving the arable plains; (see Vogel Era). These later included a branch to Springfield which was reached by January 1880. In 1882 the East and West Coast Railway League was formed and in 1884 a Royal Commission, although fully aware of the construction difficulties of the Waimakariri Valley-Arthurs Pass route, as compared with the somewhat easier but longer Hurunui Valley-Harpers Pass route, chose the more direct route. The construction of the line was rejected in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Island Fault System
The North Island Fault System (also known as North Island Dextral Fault Belt or NIFS) is a set of southwest–northeast trending seismically-active faults in the North Island of New Zealand that carry most of the dextral (right lateral) strike-slip component of the oblique convergence of the Pacific Plate with the Australian Plate. The faults include the Wairarapa Fault and Wellington Fault to the southwest, the Ruahine and Mohaka Faults in the central section and the Waimana, Waiotahi, Whakatane and Waiohau Faults to the northeast. Most of the fault system consists of dextral strike-slip faults, although towards its northeastern end the trend swings to more S-N trend and the faults become mainly oblique normal in sense as the zone intersects with the Taupo rift zone. This fault zone accommodates up to 10 mm/yr of strike-slip displacement. Faults The North Island Fault System consists of eight main fault strands and many smaller related faults.

Kermadec Trench
The Kermadec Trench is a linear ocean trench in the south Pacific Ocean. It stretches about from the Louisville Seamount Chain in the north (26°S) to the Hikurangi Plateau in the south (37°S), north-east of New Zealand's North Island. Together with the Tonga Trench to the north, it forms the -long, near-linear Kermadec-Tonga subduction system, which began to evolve in the Eocene when the Pacific Plate started to subduct beneath the Australian Plate. Convergence rates along this subduction system are among the fastest on Earth, /yr in the north and /yr in the south. Geology The Kermadec Trench is one of Earth's deepest oceanic trenches, reaching a depth of . Formed by the subduction of the Pacific Plate under the Indo-Australian Plate, it runs parallel with and to the east of the Kermadec Ridge and island arc. The Tonga Trench marks the continuation of subduction to the north. The Kermadec Trench has a southern continuation in the turbidite-filled Hikurangi Trough, but ...

Alpine Fault
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. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. However, most of the motion on the fault is strike-slip (side to side), with the Tasman district and West Coast moving North and Canterbury and Otago moving South. The average slip rates in the fault's central region are about 38 mm a year, very fast by global standards. The last major earthquake on the Alpine Fault was in c. 1717 AD, and the probability of another one occurring within the next 50 years is estimated at about 75 percent. Geographic extent and plate motion ThPacific Plate and Indo-Australian Plate boundaryforms the Macquarie Fault Zone in the Puysegur Trench off the southwestern corner of the South Island and comes onshore as the Alpine Fault jus ...

South Island
The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers , making it the world's 12th-largest island. At low altitude, it has an oceanic climate. The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook at . The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and serv ...
