This is a list of volcanoes in Antarctica.
A 2017 study claimed to have found 138 volcanoes, of which 91 were previously unknown. Some volcanoes are entirely under the ice sheet. [1] [2] Unconfirmed volcanoes are not included in the table below.
Mount Erebus is the second-highest volcano in Antarctica, the highest active volcano in Antarctica, and the southernmost active volcano on Earth. It is the sixth-highest highest point of an island, and the second most prominent mountain in Antarctica after Mount Vinson. It has a summit elevation of 3,794 metres (12,448 ft). It is located in the Ross Dependency on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. The mountain was named by Captain James Clark Ross in 1841 for his ship, the Erebus.
Brown Peak is a stratovolcano and the highest point of the Balleny Islands. It is situated on the northern part of Sturge Island.
Mount Terror is an extinct volcano about 3,230 metres (10,600 ft) high on Ross Island, Antarctica, about 20 nautical miles eastward of Mount Erebus. Mount Terror was named in 1841 by Sir James Clark Ross for his second ship, HMS Terror. The captain of Terror was Francis Crozier, a close friend of Ross for whom the nearby Cape Crozier is named.
Bellingshausen Island is one of the most southerly of the South Sandwich Islands, close to Thule Island and Cook Island, and forming part of the Southern Thule group. It is named after its discoverer, Russian Antarctic explorer Fabian von Bellingshausen (1778–1852).
Mount Discovery is a conspicuous, isolated volcanic cone, 2,680 metres (8,790 ft) high, lying at the head of McMurdo Sound and east of Koettlitz Glacier, overlooking the northwest portion of the Ross Ice Shelf. It forms the center of a three-armed mass of which Brown Peninsula is one extension to the north; Minna Bluff is a second to the east; the third is Mount Morning to the west. Mount Discovery was discovered by the British National Antarctic Expedition (1901–04) and named for their expedition ship Discovery.
Mount Griggs, formerly known as Knife Peak Volcano, is a stratovolcano, which lies 10 km behind the volcanic arc defined by other Katmai group volcanoes. Although no historic eruptions have been reported from Mount Griggs, vigorously active fumaroles persist in a summit crater and along the upper southwest flank. The fumaroles on the southwest flank are the hottest, and some of the flank fumaroles can roar so loudly that they can be heard from the valley floor. The slopes of Mount Griggs are heavily mantled by fallout from the 1912 eruption of Novarupta volcano. The summit consists of three concentric craters, the lowest and largest of which contains a recent summit cone topped by two craters. The volume of the volcanic edifice is estimated at about 25 cubic kilometers (6.0 cu mi). Isotopic analysis indicates that the source of Griggs' magma is distinct from the other Katmai volcanoes.
Mount Mageik is a stratovolcano on the Alaska Peninsula. It has no confirmed historical eruptions, but its youngest eruptive products are apparently Holocene in age. A young crater lies on the northeast flank of the central summit cone, and is the site of vigorous superheated fumarolic activity with prominent sulfur deposits. The volcanic cones are composed of andesite, basaltic andesite and dacite.
Pyre Peak, also called Seguam Volcano, is an active stratovolcano on Seguam Island in the Aleutian Islands of Alaska.
Iliamna Volcano, or Mount Iliamna, is a glacier-covered stratovolcano in the largely volcanic Aleutian Range in southwest Alaska. Located in the Chigmit Mountain subrange in Lake Clark National Park and Preserve, the 10,016-foot (3,053 m) volcano lies approximately 134 miles (215 km) southwest of Anchorage on the west side of lower Cook Inlet. It is the 25th most prominent peak in the United States.
White Island is an island in the Ross Archipelago of Antarctica. It is 15 nautical miles long, protruding through the Ross Ice Shelf immediately east of Black Island. It was discovered by the British National Antarctic Expedition (1901–04) and so named by them because of the mantle of snow which covers it.
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified.
Black Island, is an island in the Ross Archipelago, 12 nautical miles long, projecting through the Ross Ice Shelf to a height of 1,040 metres (3,410 ft).meters. It was discovered by the British National Antarctic Expedition and named by them for its appearance. The island is largely ice free and principally composed of black volcanic rock. The island's northernmost point is named Cape Hodgson, commemorating Thomas Vere Hodgson, one of the oldest members of the Discovery Expedition.
Cinnamon Butte is a group of cinder cone volcanoes and lava domes in the Cascade Range of Oregon. All of the vents are older than approximately 6,845 years as they are all covered in ash from the eruption of Mount Mazama.
The Davis Lake volcanic field, is a volcanic field with a group of andesitic cinder cones, lava flows and basaltic andesite shield volcano. The field is located east of the Cascade Range of Oregon, United States.
Mount Haddington is a massive 1,630 m (5,350 ft) high shield volcano comprising much of James Ross Island in Graham Land, Antarctica. It is 60 km (37 mi) wide and has had numerous subglacial eruptions throughout its history, forming many tuyas. Some of its single eruptions were bigger in volume than a whole normal-sized volcano. Old eruption shorelines are widespread on the volcano's deeply eroded flanks.
Mount Hodson is an ice-covered stratovolcano and the highest point on Visokoi Island, South Sandwich Islands. It might have erupted in 1830 and 1930, and the summit usually steams. Named after Sir Arnold Wienholt Hodson (1881–1944), Governor of the Falkland Islands and Dependencies, 1926–1930.
Mount Bursey is a broad, ice-covered mountain, 2,780 metres (9,120 ft) high, which forms the eastern end of the Flood Range in Marie Byrd Land, Antarctica.
Mount Kauffman is a prominent mountain, 2,365 metres (7,760 ft) high, that surmounts the northwest end of the Ames Range in Marie Byrd Land, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–65, and named by the Advisory Committee on Antarctic Names for Commander S.K. Kauffman, U.S. Navy, a staff civil engineering officer who supervised the planning and building of Plateau Station, 1965–66.
