Intraplate Earthquakes
The term intraplate earthquake refers to a variety of earthquake that occurs ''within the interior'' of a tectonic plate; this stands in contrast to an interplate earthquake, which occurs ''at the boundary'' of a tectonic plate. Intraplate earthquakes are often called "intraslab earthquakes", especially when occurring in microplates. Intraplate earthquakes are relatively rare compared to the more familiar boundary-located interplate earthquakes. Structures far from plate boundaries tend to lack seismic retrofitting, so large intraplate earthquakes can inflict heavy damage. Examples of damaging intraplate earthquakes are the devastating Gujarat earthquake in 2001, the 2012 Indian Ocean earthquakes, the 2017 Puebla earthquake, the 1811–1812 earthquakes in New Madrid, Missouri, and the 1886 earthquake in Charleston, South Carolina. Fault zones within tectonic plates The surface of the Earth is made up of seven primary and eight secondary tectonic plates, plus dozens of tertiar ...

Convergent Boundary
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more Plate tectonics, lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, Orogeny, orogenesis, destruction of lithosphere, and Deformation (geology), deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types. Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by the radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surfac ...

1755 Cape Ann Earthquake
The 1755 Cape Ann earthquake took place off the coast of the British Province of Massachusetts Bay (present-day Massachusetts) on November 18. At between 6.0 and 6.3 on the Richter scale, it remains the largest earthquake in the history of Massachusetts. No one was killed, but it damaged hundreds of buildings in Boston and was felt as far north as Nova Scotia and as far south as South Carolina. Sailors on a ship more than offshore felt the quake, and mistook it at first for their ship running aground. Many residents of Boston and the surrounding areas attributed the quake to God, and it occasioned a brief increase in religious fervor in the city. Modern studies estimate that if a similar quake shook Boston today, it would result in as much as $5 billion in damage and hundreds of deaths. Some discussion has revolved around the idea that this may have been a remotely triggered event from the 1755 Lisbon earthquake or its aftershocks. Epicenter The earthquake took place on Novembe ...

New Madrid Seismic Zone
The New Madrid Seismic Zone (), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri. The New Madrid fault system was responsible for the 1811–12 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. Since 1812, frequent smaller earthquakes have been recorded in the area. Earthquakes that occur in the New Madrid Seismic Zone potentially threaten parts of seven American states: Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee, and Mississippi. Location The -long seismic zone, which extends into five states, stretches southward from Cairo, Illinois; through Hayti, Caruthersville, and New Madrid in Missouri; through Blytheville into Marked Tree in Arkansas. It also covers a part of West Tennessee, near Reelfoot Lake, extending s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1989 Newcastle Earthquake
The 1989 Newcastle earthquake was an intraplate earthquake that occurred in Newcastle, New South Wales on Thursday 28 December. The shock measured 5.6 on the Richter magnitude scale and was one of Australia's most serious natural disasters, killing 13 people and injuring more than 160. The damage bill has been estimated at A$4 billion (or $ billion in , adjusted for inflation), including an insured loss of about $1 billion (or $ billion in , adjusted for inflation). The effects were felt over an area of around in the state of New South Wales, with isolated reports of movement in areas up to from Newcastle. Damage to buildings and facilities was reported over an area of . Death toll and damage to buildings The highest death toll and damage occurred at the Newcastle Workers Club, where the floor collapsed. Nine people were killed and many more were trapped beneath the rubble. Another three people were crushed to death when masonry from building façades collapsed onto ...

2011 Virginia Earthquake
On August 23, 2011, a magnitude 5.8 earthquake hit the Piedmont region of the U.S. state of Virginia at 1:51:04 p.m. EDT. The epicenter, in Louisa County, was northwest of Richmond and south-southwest of the town of Mineral. It was an intraplate earthquake with a maximum perceived intensity of VIII (''Severe'') on the Mercalli intensity scale. Several aftershocks, ranging up to 4.5 in magnitude, occurred after the main tremor. The quake was felt across more than a dozen U.S. states and in several Canadian provinces, and was felt by more people than any other quake in U.S. history. No deaths and only minor injuries were reported. Minor and moderate damage to buildings was widespread and was estimated by one risk-modeling company at $200 million to $300 million, of which about $100 million was insured. The earthquake prompted research that revealed that the farthest landslide from the epicenter was , by far the greatest landslide distance recorded from an ...

Mineral, Virginia
Mineral is a town in Louisa County, Virginia, United States. The population was 467 at the 2010 census. History Mineral was originally known as Tolersville, but adopted its current name when it incorporated in 1902 due to the mining industry that supported the community. It was the center of gold mining activity in Louisa County; during its heyday, there were fifteen gold mines located within two miles (3 km) of the town. A zinc and lead mine also operated in the area into the 1970s. Cuckoo, Harris-Poindexter House and Store, and the Mineral Historic District are listed on the National Register of Historic Places. At 1:51 p.m. on August 23, 2011, a 5.8 magnitude earthquake was centered 5 miles (8 kilometers) south-southwest of Mineral, at a depth of 3.7 miles (6 kilometers). According to Associated Press, it "forced evacuations of all the monuments on the National Mall in Washington and rattled nerves from Florida to Canada." The roof of Minera ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
