Types of Volcanoes

Acatenango
Acatenango

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.

Agrihan
Agrihan

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-Yakeyama
Akita-Yakeyama

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.

Ale Bagu
Ale Bagu

Ale Bagu, also known as Ummuna, is an elongated, 1031-m-high stratovolcano located SW of Erta Ale volcano. It is the highest of the Erta Ale Range volcanoes and is located west of the axis of the range.

Antisana
Antisana

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
Askja

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
Babuyan Claro Volcano

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.

Bagana
Bagana

Bagana volcano on Bougainville Island is one of the world's most active volcanoes. It has erupted frequently since its discovery in 1842. It is located on a remote part of central Bougainville Island in the Northern Solomon Province of Papua New Guinea.

Caldera
Caldera

If volcanic activity continues, the center of the caldera may be uplifted in the form of a resurgent dome such as is seen at Cerro Galán, Lake Toba, Yellowstone, etc., by subsequent intrusion of magma.

Cinder Cone
Cinder Cone

Cinder cone volcanoes are the volcanoes that most people think of when they picture a volcano erupting. That is because these are the ones that have a cone-shaped peak most people have come to associate with volcanoes in general.

Mount Akita-Komagatake
Mount Akita-Komagatake

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. The volcano last erupted from 18 September 1970 to 25 January 1971. It is the highest mountain in Akita Prefecture and the second highest in Towada-Hachimantai National Park.

Mount Aniakchak
Mount Aniakchak

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
Mount Ayalu

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.

Stratovolcano
Stratovolcano

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.

Volcanic Cone
Volcanic Cone

A volcanic cone is a triangle-shaped hill formed as material from volcanic eruptions piles up around the volcanic vent, or opening in Earth’s crust. Most volcanic cones have one volcanic crater, or central depression, at the top.
