Fueguino
Fueguino is a volcanic field in Chile. The southernmost volcano in the Andes, it lies on Tierra del Fuego's Cook Island and also extends over nearby Londonderry Island. The field is formed by lava domes, pyroclastic cones, and a crater lake. Volcanic activity at Fueguino is part of the Austral Volcanic Zone, which is formed by the subduction of the Antarctic Plate beneath the South America Plate. The subducting plate has not reached a depth sufficient for proper volcanic arc volcanism, however. The field bears no trace of glacial erosion on its volcanoes, and reports exist of volcanic activity in 1712, 1820 and 1926. Geography and geology Fueguino volcano lies in the commune of Cabo de Hornos, Chile. Cities in the region are Rio Gallegos, Puerto Natales, Punta Arenas, Rio Grande and Ushuaia. Regional Fueguino is the southernmost volcano in the Andes. The volcano to the north is Monte Burney, which lies northwest of Fueguino. Both volcanoes belong to the Austral Volcanic ...

Monte Burney
Monte Burney is a volcano in southern Chile, part of its Austral Volcanic Zone which consists of six volcanoes with activity during the Quaternary. This volcanism is linked to the subduction of the Antarctic Plate beneath the South America Plate and the Scotia Plate. Monte Burney is formed by a caldera with a glaciated stratovolcano on its rim. This stratovolcano in turn has a smaller caldera. An eruption is reported for 1910, with less certain eruptions in 1970 and 1920. Tephra analysis has yielded evidence for many eruptions during the Pleistocene and Holocene, including two large explosive eruptions during the early and mid-Holocene. These eruptions deposited significant tephra layers over Patagonia and Tierra del Fuego. Name The volcano is named after James Burney, a companion of James Cook. It is one of the many English language placenames in the region, which are the product of the numerous English research expeditions such as these by Robert FitzRoy and Phillip Parker ...

Cook Island, Tierra Del Fuego
Cook Island, also known as London Island, is an island located in the Tierra del Fuego archipelago. It lies west of Gordon Island, south of O'Brien Island and east of Londonderry Island at the head of Cook Bay, within the Alberto de Agostini National Park. Cook Island is the location of the Fueguino volcanic cones. The island was named after Captain James Cook. Cook did not visit the island, but passed the mouth of Cook Bay on 19 December 1774. The bay was named in 1828 by Captain Henry Foster.

Ushuaia
Ushuaia ( , ) is the capital of Tierra del Fuego, Antártida e Islas del Atlántico Sur Province, Argentina. With a population of nearly 75,000 and a location below the 54th parallel south latitude, Ushuaia claims the title of world's southernmost city. A much smaller municipality of less than 3,000 people, Puerto Williams in Chile, is nearer to the 55th parallel south, at a latitude of 54°56' S compared to Ushuaia at 54°48' S. Ushuaia is located in a wide bay on the southern coast of Isla Grande de Tierra del Fuego, bounded on the north by the Martial mountain range and on the south by the Beagle Channel. It is the only municipality in the Department of Ushuaia, which has an area of . It was founded on October 12, 1884, by Augusto Lasserre and is located on the shores of the Beagle Channel surrounded by the mountain range of the Martial Glacier, in the Bay of Ushuaia. Besides being an administrative center, it is a light industrial port and tourist hub. Ushuaia is located ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andean Volcanic Belt
The Andean Volcanic Belt is a major volcanic belt along the Andean cordillera in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is formed as a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones which are separated by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products, and morphology. While some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences within volcanic zones and even between neighboring volcanoes. Despite being a type location for calc-alkalic and subduction volcanism, the Andean Volcanic Belt has a broad range of volcano-tectonic settings, as it has rift systems and extensional zones, transpressional faults, subduction of mid-ocean ridges and seamount chains as well as a large range of crustal thicknesses and magma ascent paths and different amounts of crustal assim ...

South American Plate
The South American Plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African Plate, with which it forms the southern part of the Mid-Atlantic Ridge. The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the oceanic crust of the North American Plate. At the Chile Triple Junction, near the west coast of the Taitao–Tres Montes Peninsula, an oceanic ridge known as the Chile Rise is actively subducting under the South American Plate. Geological research suggests that the South American Plate is moving westward away from the Mid-Atlantic Ridge: "Parts of the plate boundaries consisting of alternations of relati ...

Transform Fault
A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone. A transform fault is a special case of a ''strike-slip fault'' that also forms a plate boundary. Most such faults are found in oceanic crust, where they accommodate the lateral offset between segments of divergent boundaries, forming a zigzag pattern. This is a result of oblique seafloor spreading where the direction of motion is not perpendicular to the trend of the overall divergent boundary. A smaller number of such faults are found on land, although these are generally better-known, such as the San Andreas Fault and North Anatolian Fault. Nomenclature Transform boundaries are also known as conservative plate boundaries because they involve no addition or loss of lithosphere at the Earth's surface. Background Geophysicist ...

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

Río Grande, Tierra Del Fuego
Río Grande is a city in Argentina, on the north coast of the eastern part of the Isla Grande de Tierra del Fuego. It has a population of 67,038, and is the industrial capital of the Tierra del Fuego Province, Argentina, Tierra del Fuego Province. It is located north-east of Ushuaia, the capital of the province. It is served by Hermes Quijada International Airport. History Sheep farming, as many other places in Patagonia, was the main impetus for population settlements beginning in the late 19th century. Abundant rivers, the seacoast, and good pastures were some of the reasons that fueled population growth. Río Grande was founded on July 11, 1921, when the central government issued a decree recognising this locality as the "Agricultural Colony of Río Grande". In the beginning, the land was subdivided among a few families, owning large estates until the agrarian reform of 1925. Cattle raising became one of the most important economic activities in the area. In 2014, the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punta Arenas
Punta Arenas (; historically Sandy Point in English) is the capital city of Chile's southernmost region, Magallanes and Antarctica Chilena. The city was officially renamed as Magallanes in 1927, but in 1938 it was changed back to "Punta Arenas". It is the largest city south of the 46th parallel south, and at the same time the most populous southernmost city in Chile and in the Americas, and due to its location, the coldest coastal city with more than 100,000 inhabitants in Latin America. It is one of the most southerly ports in the world, serving as an Antarctic gateway city. As of 1977, Punta Arenas has been one of only two free ports in Chile, the other one being Iquique, in the country's far north. Located on the Brunswick Peninsula north of the Strait of Magellan, Punta Arenas was originally established by the Chilean government in 1848 as a tiny penal colony to assert sovereignty over the Strait. During the remainder of the 1800s, Punta Arenas grew in size and impor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puerto Natales
Puerto Natales is a city in Chilean Patagonia.
