Taapaca
Taapaca is a Holocene volcanic complex in northern Chile's Arica y Parinacota Region. Located in the Chilean Andes, it is part of the Central Volcanic Zone of the Andean Volcanic Belt, one of four distinct volcanic chains in South America. The town of Putre lies at the southwestern foot of the volcano. Like other volcanoes of the Central Volcanic Zone, Taapaca formed from the subduction of the Nazca Plate beneath the South America Plate. It lies on the western margin of the Altiplano high plateau, on top of older volcanic and sedimentary units. Taapaca has mainly erupted dacite, in the form of numerous lava domes, although an andesitic stratovolcano is also present. Volcanic activity at Taapaca occurred in several stages starting during the Plio-Pleistocene. The emplacement of lava domes was often followed by their collapse and the formation of block-and-ash avalanches, and parts of the volcano underwent sector collapses (large landslides). It was at first assumed that activi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dacite
Dacite () is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained ( aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz. Dacite is relatively common, occurring in many tectonic settings. It is associated with andesite and rhyolite as part of the subalkaline tholeiitic and calc-alkaline magma series. Composition Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene ( augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form transitions to the rhyolites. The relative proportions of feldspars a ...

Viracocha
Viracocha is the great creator deity in the pre-Inca and Inca mythology in the Andes region of South America. Full name and some spelling alternatives are Wiracocha, Apu Qun Tiqsi Wiraqutra, and Con-Tici (also spelled Kon-Tiki, the source of the name of Thor Heyerdahl's raft). Viracocha was one of the most important deities in the Inca pantheon and seen as the creator of all things, or the substance from which all things are created, and intimately associated with the sea.:56 Viracocha created the universe, sun, moon, and stars, time (by commanding the sun to move over the sky) and civilization itself. Viracocha was worshipped as god of the sun and of storms. He was represented as wearing the sun for a crown, with thunderbolts in his hands, and tears descending from his eyes as rain. In accord with the Inca cosmogony, Viracocha may be assimilated to Saturn, the "old god", the maker of time or "deus faber" (god maker), corresponding to the visible planet with the longest revol ...

Quechuan Languages
Quechua (, ; ), usually called ("people's language") in Quechuan languages, is an indigenous language family spoken by the Quechua peoples, primarily living in the Peruvian Andes. Derived from a common ancestral language, it is the most widely spoken pre-Columbian language family of the Americas, with an estimated 8–10 million speakers as of 2004.Adelaar 2004, pp. 167–168, 255. Approximately 25% (7.7 million) of Peruvians speak a Quechuan language. It is perhaps most widely known for being the main language family of the Inca Empire. The Spanish encouraged its use until the Peruvian struggle for independence of the 1780s. As a result, Quechua variants are still widely spoken today, being the co-official language of many regions and the second most spoken language family in Peru. History Quechua had already expanded across wide ranges of the central Andes long before the expansion of the Inca Empire. The Inca were one among many peoples in present-day Peru who already sp ...

Aymara Language
Aymara (; also ) is an Aymaran language spoken by the Aymara people of the Bolivian Andes. It is one of only a handful of Native American languages with over one million speakers.The other native American languages with more than one million speakers are Nahuatl, Quechua languages, and Guaraní. Aymara, along with Spanish and 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 recognized minority language. Some linguists have claimed that Aymara is related to its more widely spoken neighbor, 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 features rising from prolonged cohabitation, rather than natural genealogical changes that would stem from a common protolanguage. Aymara is an agglutinating a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the shear strength of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sector Collapse
A sector collapse is the collapse of a portion of a volcano due to a phreatic eruption, an earthquake, or the intervention of new magma. Occurring on many volcanoes, sector collapses are generally one of the most hazardous volcanic events, and will often create lateral blasts. Examples A sector collapse was documented during the 1980 eruption of Mount St. Helens. It occurred due to an earthquake that was a result of the eruption. In Italy, the Sciara del Fuoco is a scar left by a sector collapse that happened over 5000 years ago. The volcano involved was the Stromboli volcano. A sector collapse occurred during an eruption of a volcano in Nicaragua Nicaragua (; ), officially the Republic of Nicaragua (), is the largest Sovereign state, country in Central America, bordered by Honduras to the north, the Caribbean Sea, Caribbean to the east, Costa Rica to the south, and the Pacific Ocean to ....

Block And Ash Flow
A block and ash flow or block-and-ash flow is a flowing mixture of volcanic ash and large (>26 cm) angular blocks commonly formed as a result of a gravitational collapse of a lava dome or lava flow. Block and ash flows are a type of pyroclastic flow and as such they form during volcanic eruptions. In contrast to other types of pyroclastic flows, block and ash flows do not contain pumice and the volume of block and ash flow deposits is usually small. Block and ash flow deposits have densities in the range of 1600 to 2000 kg/m3, two to five times greater than ash fall deposits. Some blocks in block and ash flow deposits may have thin and shiny coatings of carbon derived from charcoal formed from vegetation trapped by the flow. Volcanoes known for their production of block and ash flows since the 1990s include Mount Unzen in Japan, Mount Merapi in Java and Soufrière Hills in the Lesser Antilles The Lesser Antilles ( es, link=no, Antillas Menores; french: link=no, Petites Antill ...
