2008 Market Rasen Earthquake
On 27 February 2008 at 00:56:47.8s GMT an earthquake occurred at Market Rasen, Lincolnshire. According to the British Geological Survey the earthquake registered a reading of 5.2 on the Richter scale, with its epicentre 2.5 miles (4 km) north of Market Rasen and 15 miles (24 km) south-west of Grimsby. Duration The duration of the earthquake was confirmed as roughly 10 seconds. Spread of effect The tremors were felt across a wide area of England and Wales, from Hampshire in the south to Newcastle upon Tyne in the north, and as far west as Bangor, Northern Ireland. They were also reported in the Netherlands, Belgium, and the far north of France. Structural damage was recorded in some areas, including one case where a chimney collapsed and injured a person in Wombwell, Barnsley, South Yorkshire. Cause The earthquake was caused by the sudden rupture and motion along a strike-slip fault, beneath Lincolnshire. Earthquake motion occurred over a time span of ...

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismological Society Of America
The Seismological Society of America (SSA) is an international scientific society devoted to the advancement of seismology and the understanding of earthquakes for the benefit of society. Founded in 1906, the society has members throughout the world representing seismologists and other geophysicists, geologists, engineers, insurers, and policy-makers in preparedness and safety. History The society was established by academic, government, and other scientific and engineering professionals in the months following the April 18th San Francisco earthquake, with the first meeting of the Board of Directors taking place on December 1, 1906. Publications The Seismological Society of America publishes the ''Bulletin of the Seismological Society of America'' (''BSSA''), a journal of research in earthquake seismology and related disciplines since 1911, and ''Seismological Research Letters'' (''SRL''), which serves as a forum for informal communication among seismologists, as well as betw ...

Dextral
Sinistral and dextral, in some scientific fields, are the two types of chirality ("handedness") or relative direction. The terms are derived from the Latin words for "left" (''sinister'') and "right" (''dexter''). Other disciplines use different terms (such as dextro- and laevo-rotary in chemistry, or clockwise and anticlockwise in physics) or simply use left and right (as in anatomy). Relative direction and chirality are distinct concepts. Relative direction is from the point of view of the observer; a completely symmetric object has a left side and a right side, from the observer's point of view, if the top and bottom and direction of observation are defined. Chirality, however, is observer-independent: no matter how one looks at a right-hand screw thread, it remains different from a left-hand screw thread. Therefore, a symmetric object has sinistral and dextral directions arbitrarily defined by the position of the observer, while an asymmetric object that shows chirality may ...

Focal Mechanism
The focal mechanism of an earthquake describes the deformation in the source region that generates the seismic waves. In the case of a fault-related event it refers to the orientation of the fault plane that slipped and the slip vector and is also known as a fault-plane solution. Focal mechanisms are derived from a solution of the moment tensor for the earthquake, which itself is estimated by an analysis of observed seismic waveforms. The focal mechanism can be derived from observing the pattern of "first motions", that is, whether the first arriving P waves break up or down. This method was used before waveforms were recorded and analysed digitally and this method is still used for earthquakes too small for easy moment tensor solution. Focal mechanisms are now mainly derived using semi-automatic analysis of the recorded waveforms. Moment tensor solutions The moment tensor solution is typically displayed graphically using a so-called ''beachball'' diagram. The pattern of en ...

Ground Motion
Ground motion is the movement of the earth's surface from earthquakes or explosions. Ground motion is produced by seismic waves that are generated by sudden slip on a fault or sudden pressure at the explosive source and travel through the earth and along its surface. This can be due to natural events, such as earthquakes and volcanic eruptions, or human activities, such as the detonation of nuclear weapons. There are two main types of seismic waves: body waves and surface waves. Body waves travel through the interior of the earth, while surface waves travel along the earth's surface. Ground motion is typically caused by surface waves, which are the most destructive type of seismic waves. Ground motion is measured using a seismometer, a device that detects and records the movement of the earth's surface. Seismometers are used by seismologists to study earthquakes and other types of ground motion. The recordings produced by a seismometer are known as seismograms, and they can be use ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Wombwell
Wombwell () is a town in the Metropolitan Borough of Barnsley in South Yorkshire, England. The town in the 2011 census was split between a ward called Wombwell, as well as small parts that fell under two other wards called Darfield (specifically the area south of Pitt Street, including Broomhill) and Stairfoot (specifically the area south of Aldham Crescent). Added together, these list the town's population as roughly 15,316. Historically within the West Riding of Yorkshire, its name's origin may mean "Womba's Well", or "well in a hollow". Wombwell railway station (formerly Wombwell West) serves the Penistone and Hallam lines. Until 1959 it had another station ( Wombwell Central) on the Barnsley-Doncaster line that was closed when that line lost its passenger service. Wombwell was home to two collieries; Wombwell Main and Mitchells Main. Wombwell is close to the large shopping and leisure facilities of Cortonwood, and also has a number of local business from cafes to travel age ...

Chimney
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the ''flue''. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. In the United States, the term ''smokestack industry'' refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. The term ''smokestack'' (colloquially, ''stack'') is also used when referring to locomotive chimneys or ship chimneys, and the term ''funnel'' can also be used. The height of a chim ...
