Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from events too weak to be detectable except by sensitive instrumentation, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history. Below, earthquakes are listed by period, region or country, year, magnitude, cost, fatalities and number of scientific studies.
Sir Roderick Impey Murchison, 1st Baronet, was a Scottish geologist who served as director-general of the British Geological Survey from 1855 until his death in 1871. He is noted for investigating and describing the Silurian, Devonian and Permian systems.
The Geological Survey of Canada is a Canadian federal government agency responsible for performing geological surveys of the country developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations.
Sir Archibald Geikie was a Scottish geologist and writer.
The British Geological Survey (BGS) is a partly publicly funded body which aims to advance geoscientific knowledge of the United Kingdom landmass and its continental shelf by means of systematic surveying, monitoring and research.
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model. Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing methods, such as aerial photography and satellite imagery. Such surveys may be undertaken by state, province, or national geological survey organizations to maintain the geological inventory and advance the knowledge of geosciences for the benefit of the nation. A geological survey map typically superimposes the surveyed extent and boundaries of geological units on a topographic map, together with information at points and lines. The maps and reports created by geological survey organisations generally aim for geographic continuity and completeness in establishing the spatial patterns of near-surface rock units. The map may include cross sections to illustrate the three-dimensional interpretation. Subsurface geological and geophysical maps, providing limited coverage of deeper geology, are maintained internally by major oil companies and regulators. Some geological survey organisations have collaborated with them to include subsurface geology in their systematic surveys, for example, the Geological Atlas of the Western Canada Sedimentary Basin. Subsurface maps typically depict the three-dimensional form of geological surfaces by means of contours and cross sections. Computer-based models are increasingly used to provide more comprehensive information storage and greater flexibility of presentation. In the United States, the 50 state surveys are coordinated by the Association of American State Geologists.
The Dogger Bank earthquake of 1931 is the strongest earthquake ever recorded in the United Kingdom since measurements began. It had a magnitude of 6.1 on the Richter magnitude scale, and it caused a shaking intensity of VI (Strong) to VII on the Mercalli intensity scale. The location of the earthquake in the North Sea meant that damage was significantly less than it would have been had the epicentre been on the British mainland.
Sir Aubrey Strahan KBE FRS was a British geologist. He was elected a Fellow of the Royal Society (FRS) in 1903. He was Director of the Geological Survey of Great Britain from 1914–1920. He won the Wollaston Medal of the Geological Society of London in 1919.
Women in geology concerns the history and contributions of women to the field of geology. There has been a long history of women in the field, but they have tended to be under-represented. In the era before the eighteenth century, science and geological science had not been as formalized as they would become later. Hence early geologists tended to be informal observers and collectors, whether they were male or female. Notable examples of this period include Hildegard of Bingen who wrote works concerning stones and Barbara Uthmann who supervised her husband's mining operations after his death. Mrs. Uthmann was also a relative of Georg Agricola. In addition to these names varied aristocratic women had scientific collections of rocks or minerals.
The geology of Wales is complex and varied; its study has been of considerable historical significance in the development of geology as a science. All geological periods from the Cryogenian to the Jurassic are represented at outcrop, whilst younger sedimentary rocks occur beneath the seas immediately off the Welsh coast. The effects of two mountain-building episodes have left their mark in the faulting and folding of much of the Palaeozoic rock sequence. Superficial deposits and landforms created during the present Quaternary period by water and ice are also plentiful and contribute to a remarkably diverse landscape of mountains, hills and coastal plains.
Garwood Glacier is a glacier occupying the northwest part of Garwood Valley, in Victoria Land, Antarctica. It was first mapped by the British National Antarctic Expedition (1901–04), but was not named until 1911, when Thomas Griffith Taylor of the British Antarctic Expedition, 1910–13, named it for Edmund J. Garwood, professor of geology and mineralogy at the University of London.
The Fernie Formation is a stratigraphic unit of Jurassic age. It is present in the western part of the Western Canada Sedimentary Basin in western Alberta and northeastern British Columbia. It takes its name from the town of Fernie, British Columbia, and was first defined by W.W. Leach in 1914.
In geology, a disturbance is a linear zone of disturbed rock strata stretching for many miles across country which comprises a combination of folding and faulting. The British Geological Survey record a number of such features in South Wales including the Neath Disturbance, Pontyclerc Disturbance, Carreg Cennen Disturbance and the Cribarth Disturbance, the latter sometimes also known as the Tawe Valley or Swansea Valley Disturbance. The southwestward continuation of the Carreg Cennen Disturbance is known as the Llandyfaelog Disturbance.
