Intraplate Earthquake
An intraplate earthquake occurs in the ''interior'' of a Plate tectonics, tectonic plate, in contrast to an interplate earthquake on the ''boundary'' of a tectonic plate. They are relatively rare compared to the more familiar interplate earthquakes. Buildings far from plate boundaries are rarely protected with seismic retrofitting, so large intraplate earthquakes can inflict heavy damage. Examples of damaging intraplate earthquakes are the devastating 2001 Gujarat earthquake, the 2011 Christchurch earthquake, the 2012 Indian Ocean earthquakes, the 2017 Puebla earthquake, the 1811–1812 New Madrid earthquakes, and the 1886 Charleston earthquake. An earthquake that occurs within a subducting plate is known as an intraslab earthquake. Description The Earth's Crust (geology), crust is made up of seven primary and eight secondary Plate tectonics, tectonic plates, plus dozens of tertiary microplates. The large plates move very slowly on top of convection currents in the underlying Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megathrust Earthquake
Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (''Mw'') that can exceed 9.0. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes. The thrust faults responsible for megathrust earthquakes often lie at the bottom of oceanic trenches; in such cases, the earthquakes can abruptly displace the sea floor over a large area. As a result, megathrust earthquakes often generate tsunamis that are considerably more destructive than the earthquakes themselves. Teletsunamis can cross ocean basins to devastate areas far from the original earthquake. Terminology and mechanism The term ''megathrust'' refers to an extremely large thrust fault, typically formed at the plate interface along a subduction zo ...

1888 Río De La Plata Earthquake
The 1888 Río de la Plata earthquake occurred on 5 June measuring 5.5 on the Richter scale, and shook the upper Río de la Plata at 3:20 UTC-3. The epicentre was located southwest of Colonia del Sacramento (Uruguay) and east of Buenos Aires (Argentina), with a hypocentre at a depth of . Newspaper articles On 5 June 1888, the Montevideo journal ''La Tribuna Popular'' reported the earthquake and its effects: ''The houses' woodwork creaked loudly, lamps swung, furniture moved and paintings fell off walls. Glassware objects broke and porcelain could be seen jolting out of cupboards. Astonished at the strong earthquake, inhabitants have had a sleepless night...'' Also, a Colonia del Sacramento local journal ''La Lucha'' reported on a particular event: ''The steamer 'Saturno' en route from the neighbouring country's capital (Buenos Aires) was calmly sailing in of water along the centre of the channel when she came to a sudden halt, as though she had run aground.

2017 Botswana Earthquake
The 2017 Botswana earthquake was a magnitude 6.5 earthquake which occurred in the Central District of Botswana. It is the second largest earthquake recorded in Botswana next to the 6.7 magnitude earthquake in Maun which occurred in 1952. Earthquake The earthquake which happened at 19:40, local time according to the US Geological Survey. It was felt for 30 seconds in the country's capital of Gaborone and was reportedly felt in neighboring South Africa, Zimbabwe, and Swaziland. At least 36 students were injured in a stampede sparked by the earthquake. Geology The epicenter area of the earthquake is covered by wind-blown sediments and there is no trace of a fault at the surface prior to the earthquake. The phenomenon was suspected to be an artificial earthquake allegedly caused by hydraulic fracking activity in the Central Kalahari Game Reserve. This speculation has been dismissed by the Botswana Geoscience Institute saying that the earthquake was natural, taking note that the e ...

Epicenter
The epicenter (), epicentre, or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Determination The primary purpose of a seismometer is to locate the initiating points of earthquake epicenters. The secondary purpose, of determining the 'size' or magnitude must be calculated after the precise location is known. The earliest seismographs were designed to give a sense of the direction of the first motions from an earthquake. The Chinese frog seismograph would have dropped its ball in the general compass direction of the earthquake, assuming a strong positive pulse. We now know that first motions can be in almost any direction depending on the type of initiating rupture ( focal mechanism). The first refinement that allowed a more precise determination of the location was the use of a time scale. Instead of merely noting, or recording, the absolute motions of ...

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. Earthquake The earthquake took place on Novemb ...
