Acatenango, along with its twin volcano to the south, Volcán Fuego, overlooks the historic former capital city of Antigua, Guatemala. Acatenango, which has two principal summits, was constructed during three eruptive periods post-dating the roughly 85,000-year-old Los Chocoyos tephra from Atitlán caldera.
Agrigan volcano is an active stratovolcano and the highest of the volcanoes in the Marianas volcanic arc. It contains contains a 500-m-deep, flat-floored caldera. The last confirmed eruption was in 1917. Background: The highest of the Marianas arc volcanoes, Agrigan contains a 500-m-deep, flat-floored caldera.
Akita-Yake-yama volcano is an active stratovolcano in NW Honshu. It is one of several Japanese volcanoes named Yake-yama ("Burning Mountain"). Akita-Yake-yama is the most recently active of a group of overlapping volcanoes immediately west of the Hachimantai volcanic group.
Antisana is the 4th highest volcano in the fascinating wild region of Ecuador. It is infact one of the largest stratovolcano of the northern Andes. Antisana is completely covered with snow and glaciers which makes it one of the most daring climbing expeditions in the world.
Askja is a large basaltic central volcano that forms the Dyngjufjöll massif. It is truncated by three overlapping calderas, the largest of which is 8 km wide and may have been produced primarily from subglacial ring-fracture eruptions rather than by subsidence.
Babuyan Claro Volcano, also known as Mount Pangasun, is a volcano located on Babuyan Island, the northernmost of the Babuyan group of islands in Luzon Strait, north of the main island of Luzon in the Philippines. It is classified as one of the active volcanoes of the country with the last confirmed eruption in 1860.

Akita-Komagatake (秋田駒ヶ岳) is an active stratovolcano located 10 km east of Tazawa Lake, near the border between Akita and Iwate prefectures on Honshu Island.

Mount Aniakchak is a 3,700-year-old volcanic caldera (about 10 kilometers (6 mi) in diameter) located in the Aleutian Range of Alaska, United States. Although a stratovolcano by composition, the pre-existing mountain collapsed in a major eruption forming the caldera.
Mount Ayalu (also spelled Ayelu) is an isolated, rhyolitic stratovolcano in eastern Ethiopia. Located in Administrative Zone 3 of the Afar Region, near the eastern bank of the Awash River, this mountain has a latitude and longitude of and an altitude of 2145 meters.
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas.
