Nevado Anallajsi is a stratovolcano in Bolivia. The date of its last eruption is unknown, but its youngest lava flows appear to have erupted from a vent on the north flank of the mountain. The main composition of the volcano is andesitic and dacitic. It overlies a plateau which is composed of ignimbrite. The volcano covers an area of 368.8 square kilometres (142.4 sq mi) and is 10.2 mya old based on its erosion state, while other estimates indicate an age of 2.6 mya.
Korovin Volcano is one of four volcanic centers of the Atka Volcanic Complex, located near the town of Atka on the northeast part of Atka Island in the Aleutian Islands chain, Alaska, United States. At 5,030 feet (1,530 m), Korovin is the highest point on the island.
Illimani is the highest mountain in the Cordillera Real of western Bolivia. It lies near the cities of El Alto and La Paz at the eastern edge of the Altiplano. It is the second highest peak in Bolivia, after Nevado Sajama, and the eighteenth highest peak in South America. The snow line lies at about 4,570 metres (15,000 ft) above sea level, and glaciers are found on the northern face at 4,982 m (16,350 ft). The mountain has four main peaks; the highest is the south summit, Nevado Illimani, which is a popular ascent for mountain climbers.
Antisana is a stratovolcano of the northern Andes, in Ecuador. It is the fourth highest volcano in Ecuador, at 5,753 metres (18,875 ft), and is located 50 kilometres (31 mi) SE of the capital city of Quito.
Chikurachki is the highest volcano on Paramushir Island in the northern Kuril Islands. It is actually a relatively small volcanic cone constructed on a high Pleistocene volcanic edifice. Oxidized andesitic scoria deposits covering the upper part of the young cone give it a distinctive red color. Lava flows from the 1,816-metre (5,958 ft) high Chikurachki reached the sea and formed capes on the northwest coast; several young lava flows also emerge from beneath the scoria blanket on the eastern flank.
Mount Torbert is the highest point of the Tordrillo Mountains, a small, primarily volcanic range, northwest of Anchorage, Alaska. It is a heavily glaciated peak, and is not itself a volcano, although nearby Mount Spurr and Crater Peak are active volcanoes.
Tanaga is a 5,924-foot (1,806 m) stratovolcano in the Aleutian Range of the U.S. state of Alaska. There have been three known eruptions since 1763. The most recent was in 1914 and produced lava flows. It sits west of another stratovolcano known as Mount Takawangha, which last erupted in 1550.
The Cordillera Occidental or Western Cordillera of Bolivia is part of the Andes, a mountain range characterized by volcanic activity, making up the natural border with Chile and starting in the north with Juqhuri and ending in the south at the Licancabur volcano, which is on the southern limit of Bolivia with Chile. The border goes through the innominated point located at two-thirds of elevation of Licancabur's northeastern slope at the southwestermost point of Bolivia at 22° 49' 41" south and 67° 52' 35" west. The climate of the region is cold and inadequate for animal and plant life. Its main feature is its ground, in which are large quantities of metallic minerals including gold, silver, copper, and others.The range consists of three sections:
Michinmahuida is a glaciated stratovolcano located in Los Lagos Region of Chile. It lies about 15 km east of Chaitén volcano, and was extensively covered in ash during the 2008 eruption of Chaitén. The stratovolcano lies above the regional Liquine-Ofqui Fault zone, and the ice-covered massif towers over the south portion of Pumalín Park. It has a summit elevation of 2,450 meters above sea level.
In volcanology, a pyroclastic shield or ignimbrite shield is an uncommon type of shield volcano. Unlike most shield volcanoes, pyroclastic shields are formed mostly of pyroclastic and highly explosive eruptions rather than relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano. They typically display low-angle flank slopes and often have a central caldera caused by large eruptions. Lava is commonly extruded after explosive activity has ended. The paucity of associated Plinian fall deposits indicates that pyroclastic shields are characterized by low Plinian columns.
Pogromni Volcano is a stratovolcano on Unimak Island in the Aleutian Islands. Near it are 5 cinder cones, and a mountain called Pogromni's Sister.
Kawaikini is a shield volcano on the Hawaiian Island of Kauai and in Kauai County and measures 5,243 feet (1,598 m) in elevation. It is the summit of the island's inactive central shield volcano, Mount Waialeale. Other peaks on Kauai include: Waialeale, Namolokama Mountain, Kalalau Lookout, Keanapuka Mountain, Haupu and Nounou.
Kamakou is a shield volcano on the island of Molokai in the U.S. state of Hawaii, with a summit elevation of 4,961 feet (1,512 m). It is part of the extinct East Molokai shield volcano, which comprises the east side of the island.
Cerro Cañapa is an elongated mountain in Bolivia, with a height of 5882 m, close to the border with Chile. Note that the international border in this area is a straight line that runs from Cerro Araral to Ollagüe, leaving Cerro Cañapa completely in Bolivian territory.
Tomasamil is a highly eroded dormant volcano in south-west Bolivia, located inland from the Atacama Desert of coastal Chile. It is located about 150km south-west of the famous Salar de Uyuni salt flats and is also relatively close to the Salar de Chiguana. It is also located 6 km east of Ollagüe, another extinct ultra prominent peak on the Chile-Bolivia border. Due to its location, the peak of Tomasamil often has little to no snow. However, this is a relatively recent phenomenon, as in previous years Tomasamil often had enough precipitation for the peak to be snow-capped. The area around the mountain is dominated by pockets of occasional shrub and exposed dirt, along with expansive salt flats, typical of the region it is located in. On the lower parts of Tomasamil animals such as the vicuña, a relative of the llama, and plants such as the yareta, a plant found on high elevation areas throughout the Andes can be found.
Tunupa is a dormant volcano in the Potosí Department of southwestern Bolivia.
Kunturiri is a volcano in the Andes on the border of Bolivia and Chile which rises up to 5,762 metres (18,904 ft). On the Chilean side it is located in the Arica and Parinacota Region and on the Bolivian side in the Oruro Department, Sajama Province, Curahuara de Carangas Municipality, Sajama Canton as well as in the La Paz Department, Pacajes Province, Calacoto Municipality, Ulloma Canton.
