Vanuatu has 14 Holocene volcanoes. Note that as a scientific organization we provide these listings for informational purposes only, with no international legal or policy implications. Volcanoes will be included on this list if they are within the boundaries of a country, on a shared boundary or area, in a remote territory, or within a maritime Exclusive Economic Zone. Bolded volcanoes have erupted within the past 20 years. Suggestions and data updates are always welcome ().

There are 55 photos available for volcanoes in Vanuatu.

Nguna Island, along with Pele and Emau Islands, lie north of Efate Island (also known as Vate). Submarine calderas of varying dimensions have been hypothesized to occur in the North Vate area, and late-Pleistocene to Holocene eruptions have constructed cones with well-preserved craters.

Explosive activity that ejected ash and blocks from Niri Mbwelesu crater was observed on 16 September 1990. The Niri Mbwelesu crater formed adjacent to Mbwelesu crater in 1989 when Mbwelesu was also active but no longer contained a lava lake. During 1990 activity was concentrated in Mbwelesu, Niri Mbwelesu and Niri Mbwelesu Taten craters. Activity remained more or less constant into 1991.

A series of basaltic tuff rings and a scoria cone occupy the western tip of Ambrym, at the subaerial end of a fissure system that cuts across the length of the island. The largest tuff ring is about 1 km in diameter. The tuff rings were produced by phreatic eruptions when magma interacted with the water table or near-surface, water-saturated sediments along the coast. At higher elevations along the rift zone, scoria cones predominate.

Vanua Lava Island of Vanuatu is shown in this February 2018 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 40 km across). The majority of cones, craters, and features are in the northern part of the island, and comprise the Surematai volcano. The Pleistocene Ngere Kwon volcano formed the southernmost peninsula.

The dark lava flow lobe extending diagonally across the 1963 crater floor from the upper left is the December 1998 Lopevi intracrater lava flow (seen from the SE) after eruptive activity had resumed. The flow, ~100 m long and 10 m wide, originated from the small cone seen steaming at the upper left.

The peninsula at the top of this Space Shuttle image of Erromango Island (N is approximately to the left) is the Traitor's Head Peninsula. Three Holocene cones at Traitor's Head are the youngest on the 50-km-long island. The volcanoes initially formed an offshore island that later joined the mainland through uplift. The only documented activity at Erromango was a submarine vent that erupted in 1881.

Lava flows erupted in 2000 from vents on the lower NW flank of Lopevi volcano and flowed into the sea. Many historical eruptions have occurred along the same NW-SE-trending fissure that cuts across the island, and the lava flows along this fissure near the summit also erupted in 2000.

The northern part of the Efate island group in Vanuatu is shown in this September 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 22 km across). The three smaller islands are Nguna to the NW, immediately SE of that is Pele, and the island to the E is Emau. Several craters are visible on the islands, with a 900-m-wide crater on Emau.

On 27 November 1976 a plume, water discoloration, and sulfur odor were reported from Matthew Island. It was later noted that no noticeable eruptive event or change in island morphology had occurred since 1958. This February 1977 photo shows the steaming crater of Matthew Island volcano.

An ash cloud rising above the summit crater of Yasur volcano is seen from a village on Tanna Island in 1982. Yasur, the best-known and most frequently visited of the Vanuatu volcanoes, has been in more-or-less continuous strombolian activity since Captain Cook observed ash eruptions in 1774.

A plume is emitted from the active crater on the NW flank of Lopevi volcano in January 1999, six months after eruptive activity resumed in July 1998. The eruption took place within the elongated 1963 crater on the upper NW flank. A small lava flow erupted in December 1998 from the smaller cone onto the crater floor to the SE.

Erosional gullies in fresh tephra deposits across the northern slopes of Benbow, one of the tuff cones in the Ambrym summit caldera. The 12-km-wide caldera formed during a major Plinian eruption with dacitic pyroclastic flows about 1,900 years ago. Post-caldera eruptions, primarily from the Marum and Benbow cones, have partially filled the caldera floor and produced lava flows that ponded on the caldera floor or overflowed through gaps in the caldera rim.

Traitor's Head Peninsula of Erromango Island is shown in this July 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 10 km across). Three eroded volcanic edifices are visible, Nagat to the NE, Rantop in the center, and Oulenou with the summit crater to the W.

Clots of incandescent magma ejected from a vent on the floor of the summit crater of Yasur volcano rise to the height of the crater rim. The more-or-less continual low-level eruptive activity of Yasur, which has been occurring since it was first observed by Captain Cook in 1774, has drawn visitors to the island of Tanna. Mild strombolian eruptions are occasionally punctuated by more violent explosions.

Crescent-shaped Lake Letas partially fills the summit caldera of Gaua volcano, curving around the historically active post-caldera Mount Garat. Several young lava flows from flank vents reached the coast and form the smoother areas along the flanks of the volcano. The 6 x 9 km caldera is bound by a series of discontinuous, bifurcating faults. The dissected terrain on the SW (lower left) is part of an older series of tuff cones and lavas.

Clouds drape oval-shaped, 17-km-wide Aneityum Island in this NASA International Space Station image with north to the top. Aneityum, also known as Anatom, consists of two coalescing, dominantly basaltic Pleistocene volcanoes. Both the NW side of Inrerow Atamwan volcano (left) and the SE side of Nanawarez volcano (right) are truncated by large erosional cirques. Volcanic activity ceased during the late-Pleistocene to Holocene. Fringing reefs are visible on the northern side of the island.

Lopevi is seen here in an aerial view from the NW, with lava flows that erupted from NW-SE-trending fissures forming the barren slopes in the foreground. The small 7-km-wide island is known locally as Vanei Vollohulu. Historical eruptions date back to the mid-19th century. The island was evacuated following major eruptions in 1939 and 1960.

This vertical aerial photo shows part of the 12-km-wide summit caldera of Ambrym. The craters emitting plumes to the lower left are Marum (top) and Benbow (bottom). The caldera formed during a major Plinian eruption that included pyroclastic flows about 1,900 years ago. Post-caldera eruptions, primarily from Marum and Benbow cones, have partially filled the caldera floor and also formed a series of cones and maars along a fissure system oriented ENE-WSW.

Matthew Island is composed of two cones separated by a narrow isthmus. Only the triangular eastern portion of the small, 0.6 x 1.2 km wide island existed prior to the 1940s, after which eruptions began to build the larger western segment (part of which is seen in the photo). The western cone consists primarily of lava flows and contains a crater that is breached to the NW.

The summit crater complex of Mt. Garat with Lake Letas in the background, seen here from the S. A plume rises from the SE crater. Strong continuous degassing began following an increase in fumarolic activity in April 1991 and was continuing at the time of this July 1991 photo. Mt.

Two lakes of variable color lie with the summit caldera of Ambae volcano, as seen in this view from the W. The light blue lake in the foreground is Lake Voui (or Vui), which is enclosed in the crater of a tuff ring within the summit caldera. The dark blue Lake Manaro Lakua lies between the tuff ring and the E caldera wall. Ambae, the most voluminous volcano of the New Hebrides archipelago, forms a 16 x 38 km island. Pentecost Island appears in the background.

The steep-walled craters of the Marum cone complex at the summit of Ambrym volcano, seen from the east. Ambrym contains a 12-km-wide caldera and is one of the most active volcanoes of the New Hebrides arc. A thick pyroclastic sequence, initially dacitic, then basaltic, overlies lava flows of a pre-caldera shield volcano. Post-caldera eruptions, primarily from Marum and Benbow cones, have partially filled the caldera floor and produced lava flows that ponded on the caldera floor or overflowed through gaps in the caldera rim.

Incandescent spatter is ejected from a vent in the summit crater of Yasur volcano on 8 September 1988. The volcano has produced continuous Strombolian or Vulcanian activity since at least 1774. The mild activity seen here is occasionally interrupted by more violent explosive activity, such as during 1878, 1968, 1972, 1974-75, and 1977.

Charred vegetation marks the path of a pyroclastic flow on the SW flank of Lopevi on 19 February 2000. This view, taken 4 days later, shows part of the new 300-m-wide delta where the pyroclastic flow reached the sea. This was part of an ongoing eruption that began in July 1998. Intermittent explosive eruptions took place from the main 1963 crater (just NW of the central crater) and a small lava flow traveled 100 m within the crater.

The southern two-thirds of Vanua Lava Island is seen in this NASA International Space Station image. Suretamatai volcano forms much of the island, with the most recent activity occurring in the northern part of the island near the area with small clouds at the top of the image. The Pleistocene Ngéré Kwon volcano forms the peninsula at the bottom of the image, and small offshore islands to the right are uplifted reef limestones. Activity that began during the 19th century has consisted of moderate explosive eruptions.

Incandescent spatter ejected from a new lava lake at vent C of Mbwelesu crater at Ambrym volcano on 28 August 1999. Mbwelesu was constructed at the eastern rim of Marum crater in the west-central part of the 12-km-wide summit caldera. More frequent lava lake activity had been reported from several craters within the caldera since at least 1996. Lava lake activity had also been previously noted by infrequent visitors to the summit caldera during the late 1980s and early 1990s.

The forested cliff marks the upper caldera wall of the largely-submarine Kuwae caldera between Epi and Tongoa islands. The 6 x 12 km caldera contains two basins that cut the NW end of Tongoa Island and the flank of the late-Pleistocene or Holocene Tavani Ruru volcano on the SE tip of Epi Island. The Karua volcano lies near the northern rim of the caldera. It has formed several ephemeral islands since it was first observed in eruption during 1897.

Ten days after a new island formed during a one-day submarine eruption in 1971, scientists investigate the surface of the new land. Ash plumes had been ejected to a height of 1 km. A low island 70 x 200 m had formed, with its block-littered surface one meter above high tide level. The Karua submarine volcano was constructed within the 6 x 12 km Kuwae caldera.

An ASTER false-color satellite image of Ambae taken on 24 December 2005 shows a plume from Lake Voui above a new island that formed during an eruption that began on 27 November. The eruption built the new island with its own crater lake near the center of Lake Voui; this island has a mean diameter at this time of 525 m. Lake Manaro Lakua at the right sits within the eastern end of the caldera and is partly obscured by cloud and shadow.

The 19 February 2004 eruption of Epi B, one of several cones of the submarine East Epi volcano, is seen here from the fishing boat Azur. Seen here from the Azur as a white area beyond the man's hand, the eruption breached the surface, ejecting water and steam. Eyewitnesses reported an eruption between 16 and 24 February, and the activity was confirmed by the infrasound recordings.

The Lopevi SE-flank eruptive fissure in May 1995 is visible in this photo. The small 7-km-wide island is frequently active with both summit and flank vents, primarily on the NW and SE sides, producing moderate explosive eruptions and lava flows that reach the coast. Historical eruptions date back to the mid-19th century. Paama Island (left) and Ambrym Island (right) are in the background to the north.

The summit of Ambae is seen looking approximately SE, with Lake Voui (foreground) and Lake Manaro Lakua (also known as Manaro Ngoru) on 20 March 1995. This was following an eruption on 2 March when bubbling and black sediment ejection were observed; the next day a 3-km-high steam-and-ash plume ejected lake sediments. Convection cells ~300-400 m in diameter can be seen in Lake Voui. The eruption took place near the center of the lake, between the two small islands. No eruptive activity was observed after 3 March.

Yasur, the best-known and most frequently visited of the Vanuatu volcanoes, has been in more-or-less continuous strombolian activity since Captain Cook observed ash eruptions in 1774. This style of activity may have continued for the past 800 years. Yasur is seen here from the west across windswept Lake Siwi. Frequent ash ejection has kept the 361-m-high pyroclastic cone mostly unvegetated.

The three small islands of Nguna, Pele, and Emau at the upper left, are located N of the large island of Efete (also known as Vate). Nguna and Pele appear to be a single island in this NASA Space Shuttle image (N is to the upper left), and Emau is the small circular island at the at the top center. These islands are thought to lie along or near the southern rim of a largely-submarine caldera of uncertain dimensions that extends to the N and may have formed about 2,000 years ago.

During 5-18 September 1990 Ambrym was observed to be ejecting ash and blocks from Niri Mbwelesu crater, which formed adjacent to Mbwelesu crater in 1989 when Mbwelesu was also active. It no longer contained an active lava lake. Mbwelesu, Niri Mbwelesu, and Niri Mbwelesu Taten craters remained almost constantly active into 1991.

The elongated island of Motlav, also referred to as Mota Lava, lies in the northern Banks Islands of Vanuatu. The 12-km-long island is comprised of at least five Pleistocene basaltic stratovolcanoes capped by two well-preserved late-Pleistocene to Holocene pyroclastic cones, Tuntag and Vetnam. The low peak with a shadow above it at the lower left (SW) part of the island is Tuntog, a largely pyroclastic composite cone with a 500-m-wide summit crater. Vetnam pyroclastic cone lies in the center of the island.

On 27 May 1988 this lava lake was observed in Mbwelesu's crater, which along with Marum, was emitting ash plumes. Airline pilots had reported ash plumes below 12 km altitude from Benbow on 13 February. Vanuatu geologists reported increased activity from Benbow during 12-14 February, after which the volcano returned to normal. On 9-10 August lava flows were emitted from a new cone along the S flank, Niri Taten, and traveled towards the southern caldera wall. This eruption ended on 23 August.

A plume rises above the summit crater of Yasur, seen here from the west across Lake Siwi in 1988. Yasur has produced near-continuous Strombolian activity since at least 1774 and this style of activity may have continued for the past 800 years. The mostly-unvegetated cone is has a 400-m-wide summit crater.

An aerial overflight during World War II shows the summit of Ambae volcano from the SE. A broad cone containing three crater lakes is located at the summit within the youngest of at least two nested calderas. Post-caldera explosive eruptions formed the summit crater of Lake Voui (the light-colored lake) about 360 years ago. Lake Manaro Lakua at the lower right (also known as Manaro Ngoru) is alongside the eastern caldera wall.
