Active Fault
An active fault is a fault that is likely to become the source of another earthquake sometime in the future. Geologists commonly consider faults to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. * Active faulting is considered to be a geologic hazard - one related to earthquakes as a cause. Effects of movement on an active fault include strong ground motion, surface faulting, tectonic deformation, landslides and rockfalls, liquefaction, tsunamis, and seiches. Quaternary faults are those active faults that have been recognized at the surface and which have evidence of movement during the Quaternary Period. Related geological disciplines for ''active-fault'' studies include geomorphology, seismology, reflection seismology, plate tectonics, geodetics and remote sensing, risk analysis, and others. Location Active faults tend to occur in the vicinity of tectonic plate boundaries, and active fault research has foc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Hills
The Port Hills are a range of hills in Canterbury Region, so named because they lie between the city of Christchurch and its port at Lyttelton. They are an eroded remnant of the Lyttelton volcano, which erupted millions of years ago. The hills start at Godley Head, run approximately east–west along the northern side of Lyttelton Harbour, and continue running to the south, dividing the city from the harbour. The range terminates near Gebbies Pass above the head of the harbour. The range includes a number of summits between 300 and 500 metres above sea level. The range is of significant geological, environmental and scenic importance. History The volcano is one of two from which Banks Peninsula was originally formed 12 million years ago. The area was first populated by Māori during the 14th century. During early European settlement some 500 years later the Port Hills presented a challenging barrier between the harbour and the planned settlement of Christchurch, their st ...

Christchurch
Christchurch ( ; mi, Ōtautahi) is the largest city in the South Island of New Zealand and the seat of the Canterbury Region. Christchurch lies on the South Island's east coast, just north of Banks Peninsula on Pegasus Bay. The Avon River / Ōtākaro flows through the centre of the city, with an urban park along its banks. The city's territorial authority population is people, and includes a number of smaller urban areas as well as rural areas. The population of the urban area is people. Christchurch is the second-largest city by urban area population in New Zealand, after Auckland. It is the major urban area of an emerging sub-region known informally as Greater Christchurch. Notable smaller urban areas within this sub-region include Rangiora and Kaiapoi in Waimakariri District, north of the Waimakariri River, and Rolleston and Lincoln in Selwyn District to the south. The first inhabitants migrated to the area sometime between 1000 and 1250 AD. They hunted moa, which led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 services. ...

Richter Magnitude Scale
The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or . Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

GeoNet
GeoNet was an early international on-line services network built using microcomputers. Based on software developed in Germany by GeoNet Systems GmbH in the early 1980s, and completed in the early 1990s, it was one of the first networks to offer a comprehensive on-line services platform, and was early to market with a number of innovations. Unlike other "mailbox" systems at the time, GeoNet had a user-friendly command interface and made extensive use of distributed processing technology. History GeoNet became an important force in the European market within 15 months of introducing its first system in the early 1980s, and by 1986 had an installed base of some 25 systems in 8 countries. By the early 1990s GeoNet systems had been established in Austria, France, Germany, Guatemala, Ireland, Italy, Luxembourg, Netherlands, Poland, Portugal, Switzerland, UK, USA and USSR. Apart from the Austrian PTT and An Post in Ireland, most of the operators were independent private companies. Syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthquake Commission
The Earthquake Commission, ( mi, Kōmihana Rūwhenua), is a New Zealand Crown entity that invests in natural disaster research and education as well as providing natural disaster insurance to residential property owners. In March 2022, a bill was introduced to, among other changes, update the name of the Earthquake Commission to Toka Tū Ake – Natural Hazards Commission. It was established in its current form by the Earthquake Commission Act 1993, which was a continuation of the Earthquake and War Damage Commission, set up in 1945. It operates under the provisions of that EQC Act and of other relevant law, such as the Crown Entities Act 2004. Function of the Earthquake Commission The function of the EQC is defined in s5 of the EQC Act 1993. In short, this is to provide natural disaster insurance for residential property (contents, dwellings and land); to administer the Natural Disaster Fund; and to fund research and education on natural disasters and ways of reducing their ...

New Zealand Daylight Time
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] |
Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyttelton, New Zealand
Lyttelton (Māori: ''Ōhinehou'') is a port town on the north shore of Lyttelton Harbour / Whakaraupō, at the northwestern end of Banks Peninsula and close to Christchurch, on the eastern coast of the South Island of New Zealand. As a landing point for Christchurch-bound seafarers, Lyttelton has historically been regarded as the "Gateway to Canterbury" for colonial settlers. Until the 2020 coronavirus pandemic, the port has been a regular destination for cruise ships. It is the South Island's principal goods-transport terminal, handling 34% of exports and 61% of imports by value. In 2009 Lyttelton was awarded Category I Historic Area status by the Historic Places Trust (NZHPT) defined as "an area of special or outstanding historical or cultural heritage significance or value", not long before much of the historic fabric was destroyed in the 2011 Christchurch earthquake. Location Lyttelton is the largest settlement on Lyttelton Harbour / Whakaraupō, an inlet on the northwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
