There are 42 photos available for volcanoes in Antarctica.

This aerial view looks northeast across the trachytic shield volcano Mount Takahe, with an ice-filled 8-km-diameter caldera at the summit. The approximately 30-km-wide edifice rises about 2,000 m above the surrounding ice sheet. Eruption deposits indicate both subaqueous and subaerial eruptions, and include lavas and tephra. Möll Spur (right of center) is a prominent steep ridge of lava produced in two sequences at about 34 and 17 ka. The most recent eruption occurred around 5.6 ± 0.8 ka, producing widespread tephra distribution across West Antarctica.

A gas plume rises above the active lava lake at the summit of Erebus in December 1983, which was first observed on 24 December 1972. Lava lake activity and intermittent Strombolian eruptions have been observed during annual scientific expeditions since then. The lava is located at the bottom of an inner 100-m-deep crater, whose snow-covered rim forms a bench at the right (SW) side of the Main Crater in this 1983 photo.

Mount Siple forms the high point of Siple Island in Marie Byrd Land off the coast of Antarctica. This aerial view looks east, with dark-colored open water in the foreground and the Getz Ice Shelf between the island and Antarctica. Most volcanic features are buried in snow and ice, but the Lovill Bluff tuff cone outcrops at sea level (bottom right). Trachytic rocks at the summit have been Ar-Ar dated to about 227,000 and 169,000 years old.

U. S. Navy photo TMA 1627 F33 088, 1985.
Peter I Island, located in the Bellingshausen Sea opposite Ellsworth Land, is seen here from the north showing the Lars Christiansen Peak. This volcanic island has a steep coastline and is more dissected on the northern side, with a broader more gentle slope to the south. The most recent dated activity occurred about 100,000 years ago.

The small 1.4 x 1.7 km Penguin Island, seen here from the SW, is located off the SE coast of King George Island in the South Shetland Islands. The most prominent feature is Deacon Peak (center), a largely basaltic scoria cone with a 350-m-wide summit crater. Petrel Crater, a 300-m-wide maar, is located behind Deacon Peak, out of view in this photo. Both Deacon Peak and Petrel Crater were formed within the past few hundred years.

A gas-and-steam plume rises above the Mount Erebus summit crater in 1983. Fang Ridge is in the foreground of this view from the NE. The summit plateau across the center of the photo is the rim of a caldera containing the active summit cone.

Photo by Bill Rose, 1983 (Michigan Technological University).
A plume of ash and steam rises above Telefon Bay on 4 December 1967. The eruption occurred from submarine vents in Telefon Bay, in the northwest part of the caldera bay, forming a new island named Yelcho. A second eruption center opened on land to the east. During the peak of activity the plume rose over 10 km above the vent, and pyroclastic material covered most of Deception Island. Ashfall occurred throughout the South Shetland Islands.

This large block, about 4 m3 in size, was expelled by phreatomagmatic explosions accompanying the formation of Petrel Crater maar. The eruption, which formed a low relief 300-m-wide crater in about 1905 CE, marked the most recent recorded activity on Penguin Island. The growth rate of the reddish-orange lichens mantling the upper part of the ejected block was used to estimate the date of the eruption.

The small 1.8 x 2.2 km Paulet island, seen here in an aerial view from the west, is composed of lava flows capped by the Volcán Paulet and Volcán Larsen scoria cones. The largest and youngest cone, Paulet, contains a small circular summit crater of less than 100 m diameter. A small lake fills a maar-like depression called Volcán Andersson (center left).

Photo published in González-Ferrán (1995).
Petrel maar is a 300-m-wide crater on the eastern side of the roughly 1.5-km-wide Penguin Island. The maar was formed during an explosive eruption in the early 20th century and is surrounded by angular blocks of ejecta. The cinder cone behind Petrel maar to the SW is Deacon Peak, which marks the 180-m-high summit of the island.

Hudson Mountains volcanic field comprises about 20 volcanic nunataks. These are peaks protruding from ice, and here represent the surface expression of multiple volcanic vents. At least four nunataks can be seen faintly in this image, looking across the southern Hudson Mountains from the west. The exposed ridge in the left foreground is Webber Nunatak. The uppermost, largely ice-covered nunatak seen here is Mount Manthe, one of the largest peaks in this volcanic field and dated to about 5 million years ago. A tephra layer from this field was erupted about 2,000 years ago.

Paulet Island, seen here from the northwest, is a 1.8 x 2.2 km island located east of the tip of Graham Land Peninsula. A basal sequence of horizontal lava flows exposed in steep cliffs is capped by a well-preserved cinder cone complex (top center) with a small distinct summit crater. The darker brownish areas near and above the shoreline at the center of the photo are Adelie penguin colonies.

Deception Island in Antarctica contains a 7-km-wide caldera flooded by the sea. A narrow passageway named Neptune’s Bellows cuts through the caldera wall to the left. Numerous vents located along the caldera ring fractures around the low, 14-km-wide island have been active during historical time. Maars produced by magma-water interaction occur across the shores of the 190-m-deep Port Foster.

Photo by Juan Bastias (published in González-Ferrán, 1995).
Mount Erebus is seen here from the SW near the McMurdo research station on Ross Island and the world's southernmost active volcano. The summit has a 500 x 600 m wide, 110-m-deep crater that contains an active lava lake. The glaciated volcano was erupting when first sighted by Captain James Ross in 1841. Continuous lava lake activity has been documented since 1972, punctuated by occasional Strombolian explosions that eject bombs onto the crater rim.

Photo by Richard Waitt, 1972 (U.S. Geological Survey).
The 21-km-long Buckle Island near Antarctica is shown in this 2 March 2019 Sentinel-2 satellite image (N is at the top). It is one of three main Balleny islands of similar size with Young to the N and Sturge S and is 110 km NNE of Belousov Point.

The summit of Antarctica's Mount Erebus is the world's southernmost active volcano. It contains an elliptical 500 x 600 m wide crater whose NE side contains a 250-m-wide, 100-m-deep inner crater. The flat, snow-covered floor of the Main Crater is about 100 m below its rim. A plume rises from the inner crater that has contained an active lava lake since 1972.

Photo by Bill Rose, 1983 (Michigan Technological University).
Mount Erebus is viewed here from the SE, with the water of the Ross Sea behind it and the mountains of Victoria Land in the distance. Fang Ridge is above the snow-free slope (right) on the NE flank. The plateau right of the summit is the lava flow-filled floor of the summit caldera, inside which the active summit cone was constructed. Hut Point Peninsula is the site of the McMurdo Station and is to the left of the Ross Sea.

Photo by Bill Rose, 1983 (Michigan Technological University).
Mount Erebus is seen here from the west and is Earth's southernmost active volcano. A largely infilled caldera forms a plateau at the summit where the active cone is located. Fang Ridge is the dark area on the NE flank (left).

Murdoch Nunatak is one of a group of 16 nunataks (exposed ridges emerging from ice) in the Seal Nunataks Volcanic Field, on the east coast of northern Antarctic Peninsula. The collapse of the Larsen Ice shelf means that some nunataks can now be described as islands. Murdoch is the largest nunatak in the group, with a flat top and steep sides.

Photo by Oscar González-Ferrán (University of Chile).
Two of the three volcanoes forming Ross Island are seen in this aerial view from the west. The Erebus summit crater that contains an active lava lake is in the foreground, with glaciated Mount Terror in the distance. Numerous scoria cones and lava domes have formed across the flanks.

Photo by Bill Rose, 1983 (Michigan Technological University).
The steep Bridgeman Island, seen here from the SE, is a 600 x 900 m remnant of a much larger volcanic edifice that is mostly submerged. The base displays bedded pyroclastic rocks, and an erosional surface cut into these rocks is filled by horizontal lava flows (left center). The extensively eroded island does not display youthful volcanic features.

Photo by Oscar González-Ferrán (University of Chile).
Two summit craters at Erebus are seen in this view, with the 500 x 600 m Main Crater (left) containing an active lava lake (lower left) within the Inner Crater. A smaller inactive crater (center), referred to as Side Crater, is located immediately SW of Main Crater. The smaller West Crater is to the upper right.

An eruption darkens the sky above Antarctica's Deception Island in December 1967. Falling ash can be seen trailing from the margins of the eruption cloud. Winds distributed the ash plume to the NE and deposited 30 cm of ash over a 2 km swath across Port Foster caldera bay onto the Chilean Antarctic research station, where this photo was taken.

Photo by Bernardo Blass, 1967 (published in González-Ferrán, 1995).
These twisted girders are remnants of the Chilean Antarctic reseach station on the NE side of Deception Island. The 1969 eruption from vents along the east side of the caldera bay damaged or destroyed the Chilean and British scientific bases, as well as the island's whaling station. The 1969 eruption took place from a roughly N-S-trending line of vents that cut a glacier west of Mount Pond.

Copyrighted photo by Katia and Maurice Krafft, 1984.
A wide, dark, ash-laden eruption plume towers above Pendulum Bay on 4 December 1967, originating from vents located about 2 km NW of the Chilean research station seen in the foreground. Heavy ashfall from the eruption severely damaged the Chilean base. The destruction of the base was completed by a subsequent eruption in 1969. Members of the research party walked about 6 km S to safety at the British research station on the first day of the eruption and were then evacuated by helicopter.

Photo by Bernardo Blass, 1967 (published in González-Ferrán, 1995).
Steam rises above a new island formed during an eruption in Telefon Bay at Deception Island during 4-7 December 1967. The eruption occurred from four vents along a NE-SW line cutting across the bay, building an approximately 1-km-long, 62-m-high island which was named Yelcho, after a research vessel that was there at the time. An eruption in 1970 occurred at approximately the same location, destroying much of Yelcho, and incorporating the remnants onto a new stretch of land attached to the inner caldera wall.
