Quetrupillán
Quetrupillán ("blunted", "mutilated"; also known as Ketropillán) is a stratovolcano located in Los Ríos Region of Chile. It is situated between Villarrica and Lanín volcanoes, within Villarrica National Park. Geologically, Quetrupillán is located in a tectonic basement block between the main traces of Liquiñe-Ofqui Fault (to the west) and Reigolil-Pirihueico Fault (to the east). The volcano consists of one stratovolcano with a summit caldera, and is constructed within a field of smaller centres and a larger caldera. It was active during the late Pleistocene; some large eruptions occurred during the Holocene as well. Geology and geography The volcano is situated in the Curarrehue, Pucón and Panguipulli municipalities of the Cautín and Valdivia provinces. Towns close to Quetrupillán are Catripulli, Currarehue and Puesco. It is considered Chile's 21st most dangerous volcano.

Lanín
Lanín is an ice-clad, cone-shaped stratovolcano on the border of Argentina and Chile. It forms part of two national parks: Lanín in Argentina and Villarrica in Chile. It is a symbol of the Argentine province of Neuquén, being part of its flag and its anthem. Although the date of its last eruption is not known, it is estimated to have occurred within the last 10,000 years. Following the 1906 Valparaíso earthquake a local newspaper reported the volcano to have erupted, but a work published in 1917 by Karl Sapper disputed this.Luis E. Lara, José A. Naranjo and Hugo Moreno, 2004Lanín volcano (39.5°S), Southern Andes: geology and morphostructural evolution '' Revista Geológica de Chile'' vol. 31. The ascent is regulated by the management of Argentine National Parks and the Argentine National Gendarmerie and is technically relatively simple but has a much higher level of exposure than the neighbouring volcanoes.

Villarrica (volcano)
Villarrica ( ) ( es, Volcán Villarrica, arn, Ruka Pillañ) is one of Chile's most active volcanoes, rising above the Lake Villarrica, lake and Villarrica, Chile, town of the same name, south of Santiago. It is also known as Rucapillán, a Mapudungun, Mapuche word meaning "Pillan, great spirit's house" or " the demon's house". It is the westernmost of three large stratovolcanoes that trend northwest to southeast obliquely perpendicular to the Andes, Andean chain along the Mocha-Villarrica Fault Zone, and along with Quetrupillán and the Chilean portion of Lanín, are protected within Villarrica National Park. Guided ascents are popular during summer months. Villarrica, with its lava of basaltic-andesitic composition, is one of a small number worldwide known to have an active (but in this case intermittent) lava lake within its volcanic crater, crater. The volcano usually generates strombolian eruptions with ejection of incandescent pyroclasts and lava flows. Rainfall plus melted ...

Villarrica National Park
Villarrica National Park is located in the Andes, in the La Araucanía and Los Ríos regions of Chile, near Pucón. The centerpiece of the park is a line of three volcanoes stretching transversely to the Andean range: Villarrica, Quetrupillán, and Lanín. Other mountains in the park include Quinquilil volcano (), also known as ''Colmillo del Diablo'', and Cerro Las Peinetas, which lies on the border between Argentina and Chile. It ranges in elevation from to at Lanín Volcano. The drainage divide between the Toltén River drainage basin and the Valdivia River basin runs through the park and marks the boundary between the Cautín Province and the Valdivia Province. A portion of the park is included in the Bosques Templados Lluviosos de los Andes Australes Biosphere Reserve. Flora and fauna The park protects Valdivian temperate rainforest habitat. Roble (''Nothofagus obliqua'') and Raulí (''Nothofagus alpina'') trees are found at lower elevations. Coihues occur in the wett ...

Los Ríos Region
The Los Ríos Region (Spanish: ''Región de Los Ríos'', , ''Region of the Rivers'') is one of Chile's 16 regions, the country's first-order administrative divisions. Its capital is Valdivia. It began to operate as a region on October 2, 2007, having been created by subdividing the Los Lagos Region in southern Chile. It consists of two provinces: Valdivia and the newly created Ranco Province, which was formerly part of Valdivia Province. Economy The region's economy is based on forestry, cattle farming, tourism, manufacturing, and services. Key industries include the Valdivia Pulp Mill, Valdivia's shipyards, and the dairy facilities located in La Unión. The population of the region was 380,181 according to the 2017 census. Approximately half of the population lives in the commune of Valdivia. Government and administration The capital of Los Rios Region is Valdivia. The region's 12 communes are distributed between 2 provinces. These are: :*Valdivia Province: Including Val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subduct
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of the den ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mantle (geology)
A mantle is a layer inside a planetary body bounded below by a Planetary core, core and above by a Crust (geology), crust. Mantles are made of Rock (geology), rock or Volatiles, ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone planetary differentiation, differentiation by density. All Terrestrial planet, terrestrial planets (including Earth), a number of Asteroid, asteroids, and some planetary Natural satellite, moons have mantles. Earth's mantle The Earth's mantle is a layer of Silicate minerals, silicate rock between the Crust (geology), crust and the Earth's outer core, outer core. Its mass of 4.01 × 1024 kg is 67% the mass of the Earth. It has a thickness of making up about 84% of Earth's volume. It is predominantly solid, but in Geologic time scale, geological time it behaves as a Viscosity, viscous fluid. Partial melting of the mantle at mid-ocean ridges produ ...

Southern Volcanic Zone
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 assimi ...
