Active volcanoes

Aracar is a large conical stratovolcano in northwestern Argentina, just east of the Chilean border. It has a main summit crater about in diameter and sometimes contains crater lakes and a secondary crater. The volcano has formed, starting during the Pliocene, on top of a lava platform and an older basement. Constructed on a base with an altitude of , it covers a surface area of and has a volume of . The only observed volcanic activity was a possible steam or ash plume on March 28, 1993, seen from the village of Tolar Grande about southeast of the volcano, but with no evidence of deformation of

Ebeko () is a highly active somma volcano located on the northern end of Paramushir Island, Kuril Islands, Russia. It is one of the most active volcanoes of the Kuril Islands. Eleven eruptions have been recorded between 1793 and 1991. Most of the eruptions are small (VEI=1) with the exception of the 1859 eruption (VEI=3). Most eruptions were phreatic and explosive.

Volcán Tupungatito is the northernmost historically active stratovolcano of the southern Andes. Part of the Chilean Andes' volcanic segment, it is the northernmost member of the Southern Volcanic Zone (SVZ), which is one of several distinct volcanic belts in the Andes. Over 70 Pleistocene or Holocene age volcanoes make up this volcanic belt, which on average has one eruption per year.

Kizimen () is an active stratovolcano in the southern part of Kamchatka Peninsula, Russia.

Jólnir () was formerly a volcanic island south of Iceland. It was a former vent of Surtsey, along with Syrtlingur and Surtla. It emerged from the ocean as a result of active plate tectonics between December 1965 and July 1966. Oceanic erosion cyclically wore down the new lava as it formed, and the island sank below the surface several times.

Mutnovsky () is an active complex volcano located in the southern part of Kamchatka Peninsula, Russia, approximately 75-80 km south of Petropavlovsk-Kamchatsky. The volcano is formed from several cones and lava flows from flank eruptions that have merged into a single massif.

Tyatya (, also spelled Tiatia and known as Chachadake (爺爺岳) in Japanese) is an active volcano located in the northeastern part of Kunashir Island, Kuril Islands, Russia. It is the highest peak on the island with an elevation of . Tyatya is one of the finest examples anywhere in the world of a somma volcano, a stratovolcano whose summit has collapsed to form a caldera which has then been mostly refilled by a new, younger volcanic cone which rises above the caldera rim. thumb|150px|left|Relief Map

Chikurachki (; , Chikura-dake) 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 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.

Sabancaya is an active stratovolcano in the Andes of southern Peru, about northwest of Arequipa. It is considered part of the Central Volcanic Zone of the Andes, one of the three distinct volcanic belts of the Andes. The Central Volcanic Zone includes a number of volcanoes, some of which, like Huaynaputina, have had large eruptions, and others, such as Sabancaya and Ubinas, have been active in historical time. Sabancaya forms a volcanic complex together with Hualca Hualca to the north and Ampato to the south and has erupted andesite and dacite. It is covered by a small ice cap, which leads to
