Alto Toroni
Sillajhuay (also known as Sillajguay or Alto Toroni) is a volcano on the border between Bolivia and Chile. It is part of a volcanic chain that stretches across the border between Bolivia and Chile and forms a mountain massif that is in part covered by ice; whether this ice should be considered a glacier is debatable but it has been retreating in recent decades. The volcano has developed on top of older ignimbrites. The volcano was active within the last one million years, but not within recent times considering the heavy glacial erosion of the mountain and the widespread Periglaciation, periglacial modifications. Non-eruptive activity however occurs in the form of Deformation (volcanology), surface deformation and earthquake activity. Geography and geomorphology Sillajhuay is located in the Andes on the border between Bolivia and Chile (Communes of Chile, commune of Pica, Chile, Pica-Colchane, Tarapaca Region) although only a small easterly sector of the mountain is located i ...

Nevado Sajama
Nevado Sajama (; ) is an extinct volcano and the highest peak in Bolivia. The mountain is located in Sajama Province, in Oruro Department. It is situated in Sajama National Park and is a composite volcano consisting of a stratovolcano on top of several lava domes. It is not clear when it erupted last but it may have been during the Pleistocene or Holocene. The mountain is covered by an ice cap, and '' Polylepis tarapacana'' trees occur up to elevation. Geography and geomorphology Nevado Sajama is located in the Sajama Province of the Oruro Department in Bolivia, about from the border with Chile. Cholcani volcano lies southeast of Sajama, and another neighbouring volcano, Pomerape, resembles Sajama in its appearance. A road runs along the southeastern flank of the volcano, with additional roads completing a circle around Sajama. The village of Sajama lies on its western foot, with the village of Caripe to the northeast of the mountain and Lagunas to the southwest, and there ...

Communes Of Chile
A commune (, ) is the smallest administrative subdivision in Chile. It may contain cities, towns, villages, hamlets as well as rural areas. In highly populated areas, such as Santiago, Valparaíso and Concepción, a conurbation may be broken into several communes. In sparsely populated areas, conversely, a commune may cover a substantial rural area together with several settled areas which could range from hamlets to towns or cities. The term "commune" is ambiguous in English, but the word is commonly used in translation for "comuna", although with some controversy among translators. A comuna is similar to a "county" in Anglo-American usage and practice, and may be more universally understood as a "municipality". Each commune or municipality is governed by a directly elected body known as a municipal council (''concejo municipal'') consisting of a mayor (''alcalde'') and a group of councillors (''concejales''), for a period of four years. The communal civil service admin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olca
Olca is a stratovolcano on the border of Chile and Bolivia. It lies in the middle of a 15 km long ridge composed of several stratovolcanos. Cerro Minchincha lies to the west and Paruma to the east. It is also close to the pre-Holocene Cerro Paruma. It is andesitic and dacitic in composition, with lava flows extending several kilometres north of the peak. The only activity from the ridge during historical times was a flank eruption from 1865 to 1867. The exact source of this eruption is unclear. Gas emissions and composition The gasses emission is comprised by a single warm spring at the base and a persistent fumarole field over at the crater's dome for at least 60 years. The fumarolic field is about 0.1 km2 and the emissions measured in situ at the crater show a highly mixed magmatic system between high temperature gasses and hydrothermal fluids. The gas composition indicates low concentration of H2, CO and acidic gasses, and high concentration of H2S and hydroc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lascar (volcano)
Lascar is a stratovolcano in Chile within the Central Volcanic Zone of the Andes, a volcanic arc that spans Peru, Bolivia, Argentina and Chile. It is the most active volcano in the region, with records of eruptions going back to 1848. It is composed of two separate cones with several summit craters. The westernmost crater of the eastern cone is presently active. Volcanic activity is characterized by constant release of volcanic gas and occasional vulcanian eruptions. Lascar has been active since at least 56,000 years ago, though some argue for activity beginning 220,000 years ago. The first known activity occurred at the eastern cone and was characterized by lava flows, before shifting to the western cone where lava domes were emplaced. An eruption event known as Piedras Grandes was followed by the large Soncor eruption. A new western edifice was constructed on top of the Soncor vent, during the Holocene activity then shifted again to the eastern edifice and continues there to ...

Guallatiri
Guallatiri is a volcano in Chile with an elevation of . It is located southwest of the Nevados de Quimsachata volcanic group; some sources classify Guallatiri as a member. Guallatiri is a stratovolcano with numerous fumaroles around the summit. The summit may be a lava dome or volcanic plug, while the lower flanks of the volcano are covered by lava flows and lava domes. The volcano's eruptions have produced mostly dacite along with andesite and rhyolite. Past glaciation has left moraines on Guallatiri. A large eruption took place approximately 2,600 years ago. Guallatiri has been active in historical times with a number of eruptions, the latest in 1960. Fumarolic and seismic activity is ongoing and has resulted in the deposition of sulfur and other minerals on the volcano. The volcano is covered by an ice cap above that has shrunk and fragmented during the course of the 20th and 21st centuries. Guallatiri, along with several other volcanoes, is part of Lauca National Park an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llama
The llama (; or ) (''Lama glama'') is a domesticated South American camelid, widely used as a List of meat animals, meat and pack animal by Inca empire, Andean cultures since the pre-Columbian era. Llamas are social animals and live with others as a herd. Their wool is soft and contains only a small amount of lanolin. Llamas can learn simple tasks after a few repetitions. When using a pack, they can carry about 25 to 30% of their body weight for 8 to 13 kilometre, km (5–8 miles). The name ''llama'' (also historically spelled "lama" or "glama") was adopted by European colonization of the Americas, European settlers from Indigenous people in Peru, native Peruvians. The ancestors of llamas are thought to have originated on the Great Plains of North America about 40 million years ago and subsequently migrated to South America about three million years ago during the Great American Interchange. By the end of the last Quaternary glaciation, ice age (10,000–12,000 years ago) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aymara Language
Aymara (; also ) is an Aymaran languages, Aymaran language spoken by the Aymara people of the Bolivian Andes. It is one of only a handful of Indigenous languages of the Americas, Native American languages with over one million speakers.The other native American languages with more than one million speakers are Nahuatl, Quechua languages, and Guarani language, Guaraní. Aymara, along with Spanish language, Spanish and Quechua language, Quechua, is an official language in Bolivia and Peru. It is also spoken, to a much lesser extent, by some communities in northern Chile, where it is a Minority language, recognized minority language. Some linguists have claimed that Aymara is related to its more widely spoken neighbor, Quechua languages, Quechua. That claim, however, is disputed. Although there are indeed similarities, like the nearly identical phonologies, the majority position among linguists today is that the similarities are better explained as areal feature (linguistics), areal ...

Villa Blanca
A villa is a type of house that was originally an ancient Roman upper class country house that provided an escape from urban life. Since its origins in the Roman villa, the idea and function of a villa have evolved considerably. After the fall of the Roman Republic, villas became small farming compounds, which were increasingly fortified in Late Antiquity, sometimes transferred to the Church for reuse as a monastery. They gradually re-evolved through the Middle Ages into elegant upper-class country homes. In the early modern period, any comfortable detached house with a garden near a city or town was likely to be described as a villa; most surviving villas have now been engulfed by suburbia. In modern parlance, "villa" can refer to various types and sizes of residences, ranging from the suburban semi-detached double villa to, in some countries, especially around the Mediterranean, residences of above average size in the countryside. Roman Roman villas included: * the ''vil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
