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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tolhuin
Tolhuin is a town in the province of Tierra del Fuego, Argentina. It has 2,949 inhabitants as per the . It is located on the eastern shore of Lake Fagnano, in the southern part of the Isla Grande de Tierra del Fuego. It is the third largest settlement on the Argentine side of Tierra del Fuego after Ushuaia and Río Grande. Tolhuin was founded on October 9, 1972. The word means "''like a heart''" in Selk'nam language. It lies on National Route 3, and is the only town between the cities of Ushuaia (about 103 kilometres to the south) and Río Grande (about 133 kilometres to the north) on this motorway. Attractions There is a bakery called Panadería La Unión located near the town that has become famous on the region. Most buses going to Ushuaia stop here so their passengers can have a coffee, and eat baked goods. The walls are lined with autographed photographs of Argentine celebrities who have visited the town over the decades. ''Top Gear'' incident In 2014, Tolhuin was the site ...

Channel (geography)
In physical geography, a channel is a type of landform consisting of the outline of a path of relatively shallow and narrow body of water or of other fluids (e.g., lava), most commonly the confine of a river, river delta or strait. The word is cognate to canal, and sometimes takes this form, e.g. the Hood Canal. Formation Channel initiation refers to the site on a mountain slope where water begins to flow between identifiable banks.Bierman, R. B, David R. Montgomery (2014). Key Concepts in Geomorphology. W. H. Freeman and Company Publishers. United States. This site is referred to as the channel head and it marks an important boundary between hillslope processes and fluvial processes. The channel head is the most upslope part of a channel network and is defined by flowing water between defined identifiable banks. A channel head forms as overland flow and/or subsurface flow accumulate to a point where shear stress can overcome erosion resistance of the ground surface. Channel h ...

Fjord
In physical geography, a fjord or fiord () is a long, narrow inlet with steep sides or cliffs, created by a glacier. Fjords exist on the coasts of Alaska, Antarctica, British Columbia, Chile, Denmark, Förden and East Jutland Fjorde, Germany, Greenland, the Faroe Islands, Iceland, Ireland, Kamchatka, the Kerguelen Islands, Labrador, Newfoundland (island), Newfoundland, New Zealand, Norway, Novaya Zemlya, Nunavut, Quebec, the Patagonia region of Argentina and Chile, Russia, South Georgia Island, Tasmania, United Kingdom, and Washington (state), Washington state. Norwegian coastline, Norway's coastline is estimated to be long with its nearly 1,200 fjords, but only long coastline paradox, excluding the fjords. Formation A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and Abrasion (geology), abrasion of the surrounding bedrock. According to the standard model, glaciers formed in pre-glacial valleys with a gently sloping valley floor. The work o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magellan Straits
The Strait of Magellan (), also called the Straits of Magellan, is a navigable sea route in southern Chile separating mainland South America to the north and Tierra del Fuego to the south. The strait is considered the most important natural passage between the Atlantic and Pacific oceans. It was discovered and first traversed by the Spanish expedition of Ferdinand Magellan in 1520, after whom it is named. Prior to this, the strait had been navigated by canoe-faring indigenous peoples including the Kawésqar. Magellan's original name for the strait was ''Estrecho de Todos los Santos'' ("Strait of All Saints"). The King of Spain, Emperor Charles V, who sponsored the Magellan-Elcano expedition, changed the name to the Strait of Magellan in honor of Magellan. The route is difficult to navigate due to frequent narrows and unpredictable winds and currents. Maritime piloting is now compulsory. The strait is shorter and more sheltered than the Drake Passage, the often stormy open sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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/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 SurveyThe "USGS Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1949 Tierra Del Fuego Earthquakes
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.

Alpine Journal
The ''Alpine Journal'' (''AJ'') is an annual publication by the Alpine Club of London. It is the oldest mountaineering journal in the world. History The magazine was first published on 2 March 1863 by the publishing house of Longman in London, with Hereford Brooke George as its first editor. It was a replacement for ''Peaks, Passes, and Glaciers'', which had been issued in two series: in 1858 (with John Ball as editor), and 1862 (in two volumes, with Edward Shirley Kennedy as editor). The magazine covers all aspects of mountains and mountaineering, including expeditions, adventure, art, literature, geography, history, geology, medicine, ethics and the mountain environment, and the history of mountain exploration, from early ascents in the Alps, exploration of the Himalaya and the succession of attempts on Mount Everest, to present-day exploits. Online access Journal volumes since 1926 (bar the current issue) are freely available online. Digital scans of earlier volumes of ...

Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable ter ...

Mount Darwin (Andes)
Mount Darwin () is a peak in Isla Grande de Tierra del Fuego forming part of the Cordillera Darwin, the southernmost range of the Andes, just to the north of the Beagle Channel. Monte Darwin was for a long time considered as the highest peak in Tierra del Fuego, but that distinction corresponds to a nearby mountain unofficially named Monte Shipton (also somewhat confusingly referred to as ''Darwin'' or ''Agostini-Darwin''), which is about high and is located at . Both peaks are best climbed in late December, January, February and March. Monte Shipton was first climbed in 1962 by Eric Shipton, E. Garcia, F. Vivanco and C. Marangunic. Mount Darwin was given its name during the voyage of the ''Beagle'' by HMS ''Beagle'''s captain Robert FitzRoy to celebrate Charles Darwin's 25th birthday on 12 February 1834. A year earlier FitzRoy had named an expanse of water to the southwest of the mountain the Darwin Sound to commemorate Darwin's quick wit and courage in saving them from bei ...
