Tskhouk-Karckar or Qarqar is a group of pyroclastic cones which is located in the central part of the Siunik volcanic ridge at the border of Armenia and Azerbaijan 60 km SE of Lake Sevan. The volcanoes lie on the northwest side of Tskhouk volcano and are constructed on a volcanic basement or rhyolites, basaltic andesites and dacites. The volcanoes erupted voluminous and long lava flows, grouped in three age-based stages of varying age and conservation. Petroglyphs have been found buried under the most recent stages and broken by earthquake activity, suggesting activity between the 4th–early 3rd millennium BC and 4720 ± 140 years BP, a date established by C14 analysis on graves inside the lava flows. There is evidence indicating that the last stage of activity resulted in abandonment of the area by humans, only resuming during the Middle Ages.

Almolonga

The Almolonga volcano, also called "Cerro Quemado" or "La Muela" due to its distinct shape, is an andesitic stratovolcano in the south-western department of Quetzaltenango in Guatemala. The volcano is located near the town of Almolonga, just south of Quetzaltenango, Guatemala's second largest city.

Cerro Escorial

Cerro Escorial is a stratovolcano at the border of Argentina and Chile. It is part of the Corrida de Cori volcanic group and its youngest member. A well-preserved 1-kilometre-wide (0.6 mi) crater forms its summit area. Lava flows are found on the Chilean and smaller ones on the Argentinian side, the former reaching as far as 3–4 kilometres (1.9–2.5 mi) from the volcano. One of these is dated 342,000 years ago by argon-argon dating.

Dar-Alages is a group of six cinder lava cones south of Lake Sevan in Armenia. Fissure eruptions from Vaiyots-Sar dammed the Arpa river at Vayk and continued down the valley for 6 km. These lava flows are considered Holocene in age given the lack of a soil cover and their placement above a Pleistocene river terrace. Smbatassar cinder cones likewise generated two lava flows of 11 and 17 km length that overlie Pleistocene Yeheghis river terraces, thus also dating to the Holocene. Legends of the destruction of the towns Yegheghis and Moz in 735 AD may be linked to activity in these volcanoes.

Porak

Porak or Axarbaxar is a stratovolcano located in the Vardenis volcanic ridge. It lies about 20 km (12 mi) southeast of Lake Sevan and the volcanic field spans the border between Armenia and Azerbaijan with lava flows running into both countries. Ten satellite cones and fissure vents lie on the flanks of the volcano.

Mount Hasan

Mount Hasan is a volcano in Anatolia, Turkey. It has two summits, the 3,069 metres (10,069 ft) high eastern Small Hasan Dagi and the 3,253 metres (10,673 ft) high Big Hasan Dagi, and rises about 1 kilometre (0.62 mi) above the surrounding terrain. It consists of various volcanic deposits, including several calderas, and its activity has been related to the presence of several faults in the area and to regional tectonics.

Nemrut (volcano)

Nemrut is a dormant volcano in Eastern Turkey, close to Lake Van. The volcano is named after King Nimrod who is said to have ruled this area in about 2100 BC.

Ampato

Ampato is a dormant 6,288-metre (20,630 ft) stratovolcano in the Andes of southern Peru. It lies about 70–75 kilometres (43–47 mi) northwest of Arequipa and is part of a north-south chain that includes the volcanoes Hualca Hualca and Sabancaya, the last of which has been active in historical time.

Haruj Libyan mountain range

Haruj is a large volcanic field spread across 42,000–45,000 km2 (16,000–17,000 sq mi) in central Libya. It is one of several volcanic fields in Libya along with Tibesti, and its origin has been attributed to the effects of geologic lineaments in the crust.

Cerro del León

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.

Udokan Plateau

The Udokan Plateau is a volcanic field in Transbaikalia, Russia. It covers a surface area of 3,000 square kilometres (1,200 sq mi) northeast of Lake Baikal in North Asia. Volcanism in the Udokan Plateau included both basaltic lava flows and later individual volcanic cones. Volcanism commenced in the Miocene and continued on into the Holocene.

Tata Sabaya is a 5,430-metre (17,810 ft) high volcano in Bolivia. It is part of the Central Volcanic Zone, one of several volcanic belts in the Andes which are separated by gaps without volcanic activity. This section of the Andes was volcanically active since the Jurassic, with an episode of strong ignimbritic volcanism occurring during the Miocene. Tata Sabaya lies in a thinly populated region north of the Salar de Coipasa salt pan.

Cima volcanic field Volcanic field in San Bernardino County, California

Cima volcanic field is a volcanic field in San Bernardino County, California, close to the border with Nevada. The volcanic field covers a surface area of 600 square kilometres (230 sq mi) within the Mojave National Preserve west of the Cima Dome and consists of about 40 volcanic cones with about 60 lava flows. The volcanic cones range from simple cones over multi-cratered mountains to eroded hills, and lava flows are up to 9.1 kilometres (5.7 mi) long. At least one lava tube exists in the field and can be visited.

Ticsani

Ticsani is a volcano in Peru northwest of Moquegua. It consists of two volcanoes that form a complex: "old Ticsani", which is a compound volcano that underwent a large collapse in the past and shed 15–30 cubic kilometres (3.6–7.2 cu mi) of mass down the Rio Tambo valley. Today an arcuate ridge remains of this edifice; the other is a complex of three lava domes which were emplaced during the Holocene. Two sub-Plinian eruptions took place during the Holocene, producing the so-called "Grey Ticsani" and "Brown Ticsani" deposits; the last eruption occurred after the 1600 eruption of neighbouring Huaynaputina. The volcano is seismically active and features active hot springs and fumaroles; since 2015 the volcano is monitored by the Peruvian government.

Ubinas Volcano in Peru

Ubinas is an active stratovolcano in the Moquegua Region of southern Peru, approximately 60 kilometres (37 mi) east of the city of Arequipa. Part of the Central Volcanic Zone of the Andes, it rises 5,672 metres (18,609 ft) above sea level. The volcano's summit is cut by a 1.4-kilometre-wide (0.87 mi) and 150-metre-deep (490 ft) caldera, which itself contains a smaller crater. Below the summit, Ubinas has the shape of an upwards-steepening cone with a prominent notch on the southern side. The gently sloping lower part of the volcano is also known as Ubinas I and the steeper upper part as Ubinas II; they represent different stages in the volcano's geological history.

Lunar Crater volcanic field A volcanic field in Nye County, Nevada

Lunar Crater volcanic field is a volcanic field in Nye County, Nevada. It lies along the Reveille and Pancake Ranges and consists of over 200 vents, mostly small volcanic cones with associated lava flows but also several maars, including one maar named Lunar Crater. Some vents have been eroded so heavily that the structures underneath the volcanoes have been exposed. Lunar Crater itself has been used as a testing ground for Mars rovers and as training ground for astronauts.
