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 temperature gasses and hydrothermal fluids. The gas composition indicates low concentration of H2, CO and acidic gasses, and high concentration of H2S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, MedellÃn, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Paruma
Paruma is a stratovolcano that lies on the border of Bolivia and Chile. It is part of a ridge that contains several stratovolcanos. Paruma lies at the eastern end of the ridge, with Olca to its west. The older volcano Paruma lies to east of Paruma. Paruma has clearly been active during the Holocene, with many morphologically young lava flows on its flanks. It also has persistent fumarole A fumarole (or fumerole) is a vent in the surface of the Earth or other rocky planet from which hot volcanic gases and vapors are emitted, without any accompanying liquids or solids. Fumaroles are characteristic of the late stages of volcani ...s. One lava flow in particular extends for 7 kilometres to the south-east of the peak. Historical activity along the ridge has been confined to one eruption from 1865 to 1867, the character of which is not precisely known.

List Of Volcanoes In Bolivia
The country of Bolivia hosts numerous activeIn vulcanology and this article active volcanoes are those with Holocene eruption, that means eruptions in the last 10,000 years. and extinct volcanoes across its territory. The active volcanoes are in western Bolivia making up the Cordillera Occidental, the western limit of the Altiplano plateau. Many of the active volcanoes are international mountains shared with Chile. All Cenozoic volcanoes of Bolivia are part of the Central Volcanic Zone (CVZ) of the Andean Volcanic Belt that results due to processes involved in the subduction of Nazca Plate under the South American Plate. The Central Volcanic Zone is a major upper Cenozoic volcanic province. Apart from Andean volcanoes the geology of Bolivia host the remnants of ancient volcanoes around the Precambrian Guaporé Shield in the eastern part of the country.

Bolivia–Chile Border
The Bolivia–Chile border is an international border of South America. It separates Bolivia from Chile along Cordillera Occidental on the western edge of the Altiplano Plateau. There is an ongoing dispute about the nature of Silala River and Chile's use of its waters. Since 2021 the Bolivia–Chile border has been a major point of entry of irregular Venezuelan migrants into Chile. Migrants are aided in the crossing by human smugglers. Irregular migration has been particularly troublesome for the Chilean border town of Colchane. Indigenous Aymara communities live on both sides of the border.

Ollagüe
Ollagüe () or Ullawi () is a massive andesite stratovolcano in the Andes on the border between Bolivia and Chile, within the Antofagasta Region of Chile and the Potosi Department of Bolivia. Part of the Central Volcanic Zone of the Andes, its highest summit is above sea level and features a summit crater that opens to the south. The western rim of the summit crater is formed by a compound of lava domes, the youngest of which features a vigorous fumarole that is visible from afar. Ollagüe is mostly of Pleistocene age. It started developing more than one million years ago, forming the so-called Vinta Loma and Santa Rosa series mostly of andesitic lava flows. A fault bisects the edifice and two large landslides occurred in relation to it. Later two groups of dacitic lava domes formed, Ch'aska Urqu on the southeastern slope and La Celosa on the northwestern. Another centre named La Poruñita formed at that time on the western foot of the volcano, but it is not clear wheth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanoes Of Antofagasta Region
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...
