Bolivia–Chile border

volcano on the border of Chile and Bolivia

Licancabur () is a prominent, stratovolcano on the Bolivia–Chile border in the Central Volcanic Zone of the Andes. It is capped by a summit crater which contains Licancabur Lake, a crater lake that is among the highest lakes in the world. There are no glaciers owing to the arid climate. Numerous plants and animal species live on the mountain. The volcanoes Sairecabur and Juriques are north and east of Licancabur, respectively.

Acotango is the central and highest of a group of stratovolcanoes straddling the border of Bolivia and Chile. It is high. The group is known as Kimsa Chata and consists of three mountains: Acotango, Umurata () north of it and Capurata () south of it.

Pomerape is a stratovolcano lying on the border of northern Chile and Bolivia (Oruro Department, Sajama Province, Curahuara de Carangas Municipality). It is part of the Payachata complex of volcanoes, together with Parinacota Volcano to the south. The name "Payachata" means "twins" and refers to their appearance. It hosts glaciers down to elevations of , lower on the northern slope.

Ollagüe () or Ullawi () is a massive andesite stratovolcano in the Andes on the Bolivia–Chile border, 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.

Zapaleri is a volcano whose summit is the tripoint of the borders of Argentina, Bolivia and Chile. A number of railways are in the area. The volcano formed on top of the 2.89 mya Tara Ignimbrite from the Guacha caldera and the basement beneath the volcano is formed from Cretaceous and Tertiary rocks affected by tectonic deformation. Volcanic rocks are andesite, basalt, dacite and rhyolite. Late Cretaceous rocks are also found in the area, as are Pleistocene shoshonite volcanic rocks.

Irruputuncu is a volcano in the commune of Pica, Tamarugal Province, Tarapacá Region, Chile, as well as San Pedro de Quemes Municipality, Nor Lípez Province, Potosí Department, Bolivia. The mountain's summit is high and has two summit craters—the southernmost -wide one has active fumaroles. The volcano also features lava flows, block and ash flows and several lava domes. The volcano is part of the Andean Central Volcanic Zone (CVZ).

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.

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 fumaroles. 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

Michincha is a stratovolcano on the border of Bolivia and Chile. It is part of an east–west trending ridge of stratovolcanoes. To its east lies Olca. The only historical activity from the complex was a flank eruption from 1865 to 1867.

Umurata is a mountain in the Andes, about 5,717 m (18,757 ft) high, situated in the Cordillera Occidental on the border of Bolivia and Chile. It is located in the Arica and Parinacota Region of Chile and in the Oruro Department of Bolivia, in the Sajama Province, Turku Municipality, Chachakumani Canton. Umurata lies south of the Uqi Uqini volcano, north of the Acotango and north-east of the Wallatiri volcano. Argon-argon dating has yielded ages of 970,000±120,000 for Umurata rocks. Umurata is situated south of National Route 4 near the Chungara-Tambo Quemado pass. thumb|left|220px|M

Pukintika (Aymara puki white soil, tika adobe, Hispanicized spellings Puguintica, Puquintica, Poquentica, Puquentica) is a volcano in the Andes, about 5,407 m (17,740 ft) high, situated in the Cordillera Occidental on the border of Bolivia and Chile. It is located in the Arica and Parinacota Region of Chile and the Oruro Department of Bolivia (in Sabaya Province, Sabaya Municipality, Julo Canton). Pukintika lies to the north of the Salar de Surire, east beside Arintika volcano which is younger than Pukintika. Pukintika also features a crater lake with a surface area of . Deposits of

thumb|Olca volcano lies in the background. Olca-Paruma is a volcanic complex in Chile. Lying on the border between Chile and Bolivia, it is formed by an east–west alignment of volcanoes. From west to east, these are Cerro Paruma, Volcan Paruma, Olca, and Mencheca or Michincha. Aside from the mines of Ujina, Rosario, and Quebrada Blanca, the area is sparsely populated.
