Edgecumbe Quake007
Edgecumbe is a town in the Bay of Plenty of the North Island of New Zealand, 15 kilometres to the west of Whakatāne and eight kilometres south of the Bay's coast. It is the main service town for the agricultural region surrounding the plains of the Rangitaiki River, which flows through the town. State Highway 2 and the Tāneatua Branch railway line (disused) pass through the town. The Edgecumbe Dairy Factory, established in 1915, employs 358 people, roughly a fifth of Edgecumbe's total population.

Urban Areas Of New Zealand
Statistics New Zealand defines urban areas of New Zealand for statistical purposes (they have no administrative or legal basis). The urban areas comprise List of cities in New Zealand, cities, List of towns in New Zealand, towns and other conurbations (an aggregation of urban settlements) of a thousand people or more. In combination, the urban areas of the country constitute New Zealand's urban population. As of , the urban population made up % of New Zealand's total population. The current standard for urban areas is the Statistical Standard for Geographic Areas 2018 (SSGA18), which replaced the New Zealand Standard Areas Classification 1992 (NZSAC92) in 2018. There are four classes of urban area under SSGA18: *Major urban areas, with a population of 100,000 or more. There are seven major urban areas which combined have a population of (% of the total population). *Large urban areas, with a population of 30,000 to 99,999. There are 13 large urban areas which combined have a pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aftershock
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes, and in general can be distinguished from aftershocks in having similar magnitudes and nearly identical seismic waveforms. Distribution of aftershocks Most aftershocks are located over the full area of fault rupture and either occur along the fault plane itself or along other faults within the volume affected by the strain associated with the main shock. Typically, aftershocks are found up to a distance equal to the rupture length away from the fault plane. The pattern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foreshock
A foreshock is an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space. The designation of an earthquake as ''foreshock'', ''mainshock'' or aftershock is only possible after the full sequence of events has happened. Occurrence Foreshock activity has been detected for about 40% of all moderate to large earthquakes, and about 70% for events of M>7.0. They occur from a matter of minutes to days or even longer before the main shock; for example, the 2002 Sumatra earthquake is regarded as a foreshock of the 2004 Indian Ocean earthquake with a delay of more than two years between the two events. Some great earthquakes (M>8.0) show no foreshock activity at all, such as the M8.6 1950 India–China earthquake. The increase in foreshock activity is difficult to quantify for individual earthquakes but becomes apparent when combining the results of many different events. From such combined observations, the increase before the mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myocardial Infarction
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often it occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat or feeling tired. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, ... [...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 DC Class Locomotive
The New Zealand DC class locomotive is a type of diesel-electric mainline locomotive on the New Zealand rail network, operated by KiwiRail on freight trains, and formerly on long-distance passenger trains. The class was rebuilt from the DA class in the late 1970s and early 1980s, mainly in Australia. After the DA class, they were the most numerous class of diesel locomotive on New Zealand's railway network and remained numerically dominant until the mid-2010s when withdrawals began. History The locomotives started life as DA class, built by General Motors Canada between 1955 and 1967. Between 1978 and 1983, 85 of the later-build DAs were rebuilt. Because of a backlog of locomotives requiring heavy maintenance, Clyde Engineering were awarded a contract to rebuild 35 DA class as EMD model G22ARs, with upgraded engines, new cabs and low short hoods of a style similar to the DX class introduced earlier in the 1970s and the DF class being introduced at the time.

Tranz Rail
Tranz Rail, formally Tranz Rail Holdings Limited (New Zealand Rail Limited until 1995), was the main Rail transport in New Zealand, rail operator in New Zealand from 1991 until it was purchased by Toll Holdings in 2003. History The New Zealand railway network was initially built by Provinces of New Zealand, provincial governments, starting with the Ferrymead Railway in 1863. From 1880, a central Government department, the New Zealand Railways Department, was responsible for operating most of the growing railway network. A few private lines were built, but only one, the Wellington and Manawatu Railway Company (W&MR) achieved any measure of success. The W&MR was nationalised in 1908. In 1931, due to increasing competition from road carriers, the Transport Licensing Act 1931 was passed, restricting road cartage and giving the railways department a monopoly on long-distance freight. In 1982, the same year the land transport sector was deregulated, the Railways Department was reconst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawerau
Kawerau is a town in the Bay of Plenty region of the North Island of New Zealand. It is situated 100 km south-east of Tauranga and 58 km east of Rotorua. It is the seat of the Kawerau District Council, and the only town in Kawerau District. Kawerau is a small community, with an economy that is largely driven by the nearby pulp and paper mill that is run by Norske Skog and OJI Fibre Solutions. It is located along State Highway 34, southwest of Onepu, and is the terminus of the East Coast Main Trunk Railway, and the commencing point of the Murupara Branch railway. Kawerau was one of the worst-affected towns in the 1987 Edgecumbe earthquake. History and culture European settlement Kawerau, one of the youngest towns in New Zealand, was founded in 1953 as a mill town for the new Tasman pulp and paper mill. The site for the mill was chosen because of the ready availability of geothermal energy, water from the Tarawera River and the large supply of pine timber from the ...

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 ...
