Cerro del Azufre (Spanish pronunciation: [ˈsero ðel aˈsufɾe] ) is a stratovolcano located in El Loa Province, Antofagasta Region, Chile. It is part of a chain of volcanoes that separate Upper Loa River basin from Salar de Ascotán basin and is flanked to the west by a dacitic lava dome called Chanka or Pabellón. The 6000 metre volcanoes San Pedro and San Pablo are located to the southwest of Cerro del Azufre.
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice and ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica, with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as 15 km (9.3 mi).
The Antofagasta Region is one of Chile's sixteen first-order administrative divisions. It comprises three provinces, Antofagasta, El Loa and Tocopilla. It is bordered to the north by Tarapacá and by Atacama to the south and is the second-largest region of Chile. To the east it borders Bolivia and Argentina. The capital of the region is the port city of Antofagasta, another important city being Calama. The main economic activity is copper mining in the giant porphyry copper systems located inland.
Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about 1,250,000 square kilometres (480,000 sq mi) of Antarctica, although all claims are suspended under the Antarctic Treaty.
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 5,868 metres (19,252 ft) 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.
San Pedro de Inacaliri River, or called simply San Pedro River, is a river of Chile located in El Loa Province, Antofagasta Region. It begins at the confluence of the rivers Silala and Cajón, at an elevation over 4,000 m asl.
Calama is a city and commune in the Atacama Desert in northern Chile. It is the capital of El Loa Province, part of the Antofagasta Region. Calama is one of the driest cities in the world with average annual precipitation of just 5 mm (0.20 in). The River Loa, Chile's longest, flows through the city. Calama has a population of 147,886.
Cerro Bayo is a complex volcano on the northern part border between Argentina and Chile. It consists of four overlapping stratovolcanoes along a north-south line. The main volcano fauce is located on the Argentine side, thought the summit of the complex is just west of the border, in Chile. The volcano is about 800,000 years old, but it is associated with ongoing ground uplift encompassing also the more northerly Lastarria and Cordón del Azufre volcanoes. The 5,401-metre (17,720 ft) high summit is the source of two viscous dacitic lava flows with prominent levees that traveled to the north.
Falso Azufre is a complex volcano at the border of Argentina and Chile.
The Biobío River is the second largest river in Chile. It originates from Icalma and Galletué lakes in the Andes and flows 380 km to the Gulf of Arauco on the Pacific Ocean.
The Loa River is a U-shaped river in Chile's northern Antofagasta Region. At 440 km long, it is the country's longest river and the main watercourse in the Atacama Desert.
Salar de Atacama is the largest salt flat in Chile. It is located 55 km (34 mi) south of San Pedro de Atacama, is surrounded by mountains, and has no drainage outlets. In the east it is enclosed by the main chain of the Andes, while to the west lies a secondary mountain range of the Andes called Cordillera de Domeyko. Large volcanoes dominate the landscape, including the Licancabur, Acamarachi, Aguas Calientes and the Láscar. The last is one of the most active volcanoes in Chile. All of them are located along the eastern side of the Salar de Atacama, forming a generally north-south trending line of volcanoes that separate it from smaller endorheic basins.
Paniri is a stratovolcano located in El Loa Province, Antofagasta Region, Chile, and near the border with Bolivia. To its northwest lie the twin volcanoes San Pedro and San Pablo, and to its southeast lies Cerro del León, from which it is separated by the huge Chao lava dome.
San Pedro is a Holocene composite volcano in northern Chile and one of the tallest active volcanoes in the world. Part of the Chilean Andes' volcanic segment, it is part of the Central Volcanic Zone of the Andes, one of the four tracts of the Andean Volcanic Belt. This region of volcanism includes the world's two highest volcanoes Ojos del Salado and Llullaillaco. San Pedro, like other Andean volcanoes, was formed by the subduction of the Nazca Plate beneath the South America Plate. It has a neighbouring volcano, San Pablo, and is itself formed by two separate edifices usually known as the Old Cone and the Young Cone. These edifices are formed by rocks ranging from basaltic andesite over andesite to dacite and are emplaced on a basement formed by Miocene volcanic rocks.
Copiapó, also known as Azufre, is a stratovolcano located in the Atacama Region of Chile. The volcano separates the two portions in which Nevado Tres Cruces National Park is divided. In its vicinity lies Ojos del Salado. At its summit an Inca platform can be found.
Tinguiririca River is a river of Chile located in the Libertador General Bernardo O'Higgins Region. It rises in the Andes, at the confluence of the rivers Las Damas and Del Azufre. From its source, it flows northwest for about 56 km to the vicinity of the city of San Fernando. In this portion of its course, the river receives the waters of the tributaries Clarillo and Claro. Then the river flows southwest and then turns northwest to empty into Rapel Lake.
Cerro del León is a stratovolcano located in El Loa province, Antofagasta Region, Chile. It is part of the Chilean Central Volcanic Zone and forms a volcanic lineament with neighbouring Paniri and Toconce that was active into the Holocene. Cerro del León itself was constructed in three stages by andesitic–dacitic lava flows and was subject to glacial erosion.
Volcán Linzor is a stratovolcano on the border between Bolivia and Chile. In its vicinity lie Laguna Colorada and Cerro del León.
The San Francisco Pass is a pass over the Andes mountains which connects Argentina and Chile. The highest point of this pass is at 4,726 m (15,505 ft) AMSL.
Palpana is a volcano in the Andes of Chile. It has a summit elevation of 6,040 metres above sea level and is part of the dividing range between Upper Loa River basin and Salar de Ascotán basin. Together with Inacaliri and Azufre, it forms a 50 kilometres (31 mi) long volcanic chain constructed along the Inacaliri lineament. The volcano rises above an ignimbrite plain that in the area reaches an altitude of 3,700 metres (12,100 ft).
Portezuelo del Cajón, also known as Hito Cajón, is a mountain pass on the border between Chile and Bolivia, located on the lower southeast flank of Juriques volcano, close to the Licancabur volcano. While Bolivian customs are completed at the top of the pass, Chilean customs are completed in the town of San Pedro de Atacama, 45 kilometres (28 mi) away. The road over the pass begins at the junction with Chile Route 27, close to Cerro Toco.
Salar de Ascotán, also known as Salar de Cebollar, is a salt flat in northern Chile. Its drainage basin is 1,455 square kilometers (562 sq mi) and is shared with Bolivia. The basin is bordered on the north by the Salar de Carcote basin, on the east by small endorheic basins, including those of Laguna Cañapa and Laguna Hedionda, from which is separated by the crest of the Cerros de Cañapa, Cerro Araral and others. To the south, the basin is bordered by the San Pedro de Inacaliri River basin, while to the west the drainage divide between the salt flat and the Upper Loa River basin is marked by the summits of a chain of volcanoes culminating in Palpana.
Acamarachi is a 6,046-metre (19,836 ft) high volcano in northern Chile. In this part of Chile, it is the highest volcano. Its name means "black moon". It is a volcano in the Central Volcanic Zone of the Andes, a zone of strong volcanic activity during the last million years. Old volcanoes in the area are well-preserved, due to the dry climate.
The Smithsonian Institution's Global Volcanism Program (GVP) documents Earth's volcanoes and their eruptive history over the past 10,000 years. The GVP reports on current eruptions from around the world as well as maintaining a database repository on active volcanoes and their eruptions. In this way, a global context for the planet's active volcanism is presented. Smithsonian reporting on current volcanic activity dates back to 1968, with the Center for Short-Lived Phenomena (CSLP). The GVP is housed in the Department of Mineral Sciences, part of the National Museum of Natural History, on the National Mall in Washington, D.C.
The Smithsonian Institution, founded on August 10, 1846 "for the increase and diffusion of knowledge," is a group of museums and research centers administered by the Government of the United States. The institution is named after its founding donor, British scientist James Smithson. Originally organized as the "United States National Museum," that name ceased to exist as an administrative entity in 1967.
