1949 Tierra Del Fuego Earthquake
The 1949 Tierra del Fuego earthquakes occurred slightly more than eight hours apart on 17 December. Their epicenters were located in the east of the Chilean Tierra del Fuego Province, close to the Argentine border on the island of Tierra del Fuego. The two shocks measured 7.7 and 7.6 on the moment magnitude scale and were the most powerful ever recorded in the south of Argentina and one of the most powerful in austral Chile. They were felt with intensities as high as VIII (''Severe'') on the Mercalli intensity scale, and affected the settlements of Punta Arenas and Río Gallegos.

Doublet Earthquake
__NOTOC__ In seismology, doublet earthquakes – and more generally, multiplet earthquakes – were originally identified as multiple earthquakes with nearly identical waveforms originating from the same location. They are now characterized as single earthquakes having two (or more) main shocks of similar magnitude, sometimes occurring within tens of seconds, but sometimes separated by years. The similarity of magnitude – often within 0.4 magnitude – distinguishes multiplet events from aftershocks, which start at about 1.2 magnitude less than the parent shock ( Båth's law) and decrease in magnitude and frequency according to known laws. Doublet/multiplet events also have nearly identical seismic waveforms, as they come from the same rupture zone and stress field, whereas aftershocks, being peripheral to the main rupture, typically reflect more diverse circumstances of origin. Multiplet events overlap in their focal fields (rupture zones), which can be up 100 kilometers acros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Earthquakes In Chile
__NOTOC__ Chile lay in a region which is adjacent to the fast-moving Nazca Plate, and has high tectonic activity. The records for earlier centuries are apparently incomplete. Of the world's 46 known earthquakes with M ≥ 8.5 since the year 1500, one-third occurred in Chile and are shown in the map to the side. Some virtually have the same epicenters like the 1604 and 1868 (in Arica), the 1730 and 1822 (in Valparaíso), the 1751 and 1835 (in Concepción), and the 1575 and 1837 (in Valdivia). The strongest known recorded in modern times was also in Chile, the 1960 Valdivia earthquake.

Presidential Republic (1925–1973)
The Presidential Republic ( es, República Presidencial) is the period in the history of Chile spanning from the approval of the 1925 Constitution on 18 September 1925, under the government of Arturo Alessandri Palma, to the fall of the Popular Unity government headed by the President Salvador Allende on 11 September 1973. The period spans the same time as the "Development inwards" (''Desarrollo hacia adentro'') period in Chilean economic history. Carlos Ibáñez and Arturo Alessandri Palma Headed by Colonel Marmaduque Grove, left-wing troops deposed the September Junta in the 1925 coup, and handed power to General Pedro Dartnell as interim president, with the hope of recalling Arturo Alessandri Palma from exile. Dartnell, however, decided to form another junta, the January Junta, which ended with Alessandri's return on March 20, 1925. Alessandri had a new Constitution drafted, and approved in a referendum by 134,421 voters on August 30. The Constitution, which was promulga ...

History Of Magallanes Region
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

History Of Tierra Del Fuego
Tierra del Fuego (, ; Spanish for "Land of the Fire", rarely also Fireland in English) is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of , and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel and the southernmost islands. The southernmost extent of the archipelago is just north of latitude 56°S. The earliest known human settlement in Tierra del Fuego dates to approximately 8,000 BC. Europeans first explored the islands during Ferdinand Magellan's expedition of 1520. ''Tierra del Fuego'' and similar namings stem from sightings of the many bonfires that the natives built. Settlement by those of European descent and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquakes In Argentina
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes ca ...

List Of Earthquakes In 1949
This is a list of earthquakes in 1949. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Three events took up the vast majority of the deaths for 1949. The events happened during a volatile mid year period seismically speaking. Firstly in Tajikistan in July 12,000 were killed. A few weeks later in early August a quake struck Ecuador leaving 6,000 dead. In mid August Turkey suffered from an earthquake leaving another 320 dead. Also in this part of the year was the largest quake, a magnitude 8.2 in Canada Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's ...

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. Surface damage Before the instrumental period of earthquake observation, the epicenter was thought to be the location where the greatest damage occurred, but the subsurface fault rupture may be long and spread surface damage across the entire rupture zone. As an example, in the magnitude 7.9 Denali earthquake of 2002 in Alaska, the epicenter was at the western end of the rupture, but the greatest damage was about away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from . Continental earthquakes below are rare whereas in subduction zone earthquakes can originate at depths deeper than . Epicentral distance During an earthquake, seismic waves propagate in all directions from the hypocenter. Seismic shadowing occurs on the opposite s ...
