Concepción is one of two volcanoes that form the island of Ometepe, which is situated in Lake Nicaragua in Nicaragua, Central America.
Cerro El Cóndor is a stratovolcano in Argentina.
Viedma is a subglacial volcano whose existence is questionable. It is supposedly located below the ice of the Southern Patagonian Ice Field, an area disputed between Argentina and Chile. The 1988 eruption deposited ash and pumice on the ice field and produced a mudflow that reached Viedma Lake. The exact position of the edifice is unclear, both owing to the ice cover and because the candidate position, the "Viedma Nunatak", does not clearly appear to be of volcanic nature.
Mount Belinda is a stratovolcano on Montagu Island, in the South Sandwich Islands of the Scotia Sea. A part of the British Overseas Territory, South Georgia and the South Sandwich Islands, Mount Belinda is also the highest peak in the South Sandwich Islands, at 1,370 m (4,490 ft).
Kambalny is a stratovolcano located in the southern part of the Kamchatka Peninsula, Russia. It is the southernmost active volcano of Kamchatka. It has erupted mafic rocks. It has a summit crater as well as five cinder cones on its flanks which are the source of lava flows.
Taunshits is a stratovolcano located in the eastern part of the Kamchatka Peninsula, Russia.
Kostakan is a north-south trending chain of cinder cones located in the southern part of the Kamchatka Peninsula, Russia.
Nemo Peak is a stratovolcano located at the northern end of Onekotan Island, Kuril Islands, Russia. It is truncated by two nested calderas, with the cone of Nemo Peak itself rising in the southwest end of the youngest caldera and a crater lake partially filling the northeast part, named Ozero Chernoye.
Kīlauea Iki is a pit crater that is next to the main summit caldera of Kīlauea on the island of Hawaiʻi in the Hawaiian Islands. It is known for its eruption in 1959 that started on November 14th and ended on December 20th, producing lava fountaining up to 1900 feet and a lava lake in the crater. Today, the surface of the lava lake has cooled and it is now a popular hiking destination to view the aftermath of an eruption.
Yate Volcano is a large, glaciated stratovolcano located in the southern Andes, in the Los Lagos Region of Chile, south of the Reloncaví Estuary. Yate lies on the major regional Liquiñe-Ofqui Fault Zone, and is located 10 km north-east of the smaller Hornopiren volcano. The last known eruption occurred in 1090 CE. There are no historical records of recent volcanic activity, but there is strategic evidence of smaller eruptions sometime in the Holocene. The volcano is named after Juan Yates, also known as John Yates, a settler of Puerto Americano who played a significant role in the exploration and colonisation of Patagonia.
A rift zone is a feature of some volcanoes, especially shield volcanoes, in which a set of linear cracks develops in a volcanic edifice, typically forming into two or three well-defined regions along the flanks of the vent. Believed to be primarily caused by internal and gravitational stresses generated by magma emplacement within and across various regions of the volcano, rift zones allow the intrusion of magmatic dykes into the slopes of the volcano itself. The addition of these magmatic materials usually contributes to the further rifting of the slope, in addition to generating fissure eruptions from those dykes that reach the surface. It is the grouping of these fissures, and the dykes that feed them, that serves to delineate where and whether a rift zone is to be defined. The accumulated lava of repeated eruptions from rift zones along with the endogenous growth created by magma intrusions causes these volcanoes to have an elongated shape. Perhaps the best example of this is Mauna Loa, which in Hawaiian means "long mountain", and which features two very well defined rift zones extending tens of kilometers outward from the central vent.
Mentolat is an ice-filled, 6 km (4 mi) wide caldera in the central portion of Magdalena Island, Aisén Province, Chilean Patagonia. This caldera sits on top of a stratovolcano which has generated lava flows and pyroclastic flows. The caldera is filled with a glacier.
Tarso Toh is a volcanic field located in Chad, north of Tarso Toussidé volcano. It fills valleys and plains over an area of 80 km in east-west direction and 20–30 km in north-south direction. It contains 150 scoria cones and two maars.
Hualca Hualca is an extinct volcano in Arequipa Region in the Andes of Peru. It has a height of 6,025 metres (19,767 ft). It is located at the Peruvian province of Caylloma.
Ceboruco is a dacitic stratovolcano located in Nayarit, Mexico, northwest of the Trans-Mexican Volcanic Belt. The largest eruption, the Jala Plinian eruption, was around 930 AD ±200, VEI 6, releasing 11 cubic kilometres (2.6 cu mi) of tephra. The most recent and best documented eruption from Ceboruco lasted from 1870–1875, with fumarole activity lasting well into the 20th century. The mountain features one large caldera, created during the Jala eruption, with a smaller crater nested inside that formed when the Dos Equis lava dome collapsed during the Coapales eruption around 1100 AD. Within both of these craters, are several explosive volcanic features, including scoria deposits, lava domes, and pyroclastic domes, or cinder cone volcanoes.
The magma supply rate measures the production rate of magma at a volcano. Global magma production rates on Earth are about 20–25 cubic kilometres per year (4.8–6.0 cu mi/a).
Tutupaca is a volcano in the region of Tacna in Peru. It is part of the Peruvian segment of the Central Volcanic Zone, one of several volcanic belts in the Andes. Tutupaca consists of three overlapping volcanoes formed by lava flows and lava domes made out of andesite and dacite, which grew on top of older volcanic rocks. The highest of these is usually reported to be 5,815 metres (19,078 ft) tall and was glaciated in the past.
Tarso Yega is a stratovolcano in Tibesti, with a summit caldera that is 19 by 20 kilometres wide and 300 metres (980 ft) deep. The summit of the volcano reaches a height of 2,972 metres (9,751 ft), and its caldera is the largest caldera of the Tibesti. Neighbouring volcanoes include Doudriki east, Ehi Dosoatou south and Ehi Fodoboro southwest of the caldera. The Enneri Yega river drains the caldera westward and then south, before joining the Enneri Debarsar; in the past (Holocene) the rivers reached Lake Chad and lakes formed in Tarso Yega.
The Alberca de Los Espinos or Alberca de Santa Teresa is a volcanic crater lake that is located in a state protected area that includes 142 hectares within the Mexican state of Michoacán.
