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.

Craters and cones of Suretamatai in Vanua Lava Island, Vanuatu, are visible across this February 2018 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 10 km across). The field covers much of the island, with a NNE-SSW trend of cones (shown here), with the largest edifice towards the northern end having formed multiple craters along a NW-SE trend. Geothermal activity continues.

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.

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.

Photo by Hunting Surveys, London (published in Green and Short, 1971). 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.

Photo by Michel Lardy, 1990 (ORSTROM, Vanuata). 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.

NASA Space Shuttle image STS68-220-4, 1994 (http://eol.jsc.nasa.gov/). 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.

Photo by Alain Melchior, 1988. 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.

NASA Space Shuttle image STS068-206-50, 1994 (http://eol.jsc.nasa.gov/). An ash column is ejected from one of several vents on the floor of the summit crater of Yasur volcano in 1982. The frequent eruptions of this volcano have drawn visitors to Tanna Island.

Copyrighted photo by André Demaison, 1982 (courtesy of Katia and Maurice Krafft). 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.

Photo by John Seach, 2000. 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.

Satellite image courtesy of Planet Labs Inc., 2019 (https://www.planet.com/). 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.

A plume rises from a crater lake inside the new island formed during an eruption at Ambae beginning on 27 November 2005. This 9 January 2006 view looks toward the N. The new island was more than 500 m wide at this time and contained an internal lake.

The ash-mantled slopes of the northern side of Marum cone are cut by erosional furrows. Marum is one of several historically active cones constructed within the 12-km-wide caldera of Ambrym. The cone lies in the west-central part of the caldera and is the highest of the post-caldera cones.

Photo by Alain Melchior. Discolored water rises from the submarine Epi B vent in December 1958. This vent is one of the several East Epi cones located offshore of Epi Island in Vanuatu. Ephemeral islands were formed during eruptions in 1920 and 1953.

Copyrighted photo by Roland Priam, 1958 (courtesy of IRD, New Caledonia). 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.

Copyrighted photo by Marco Fulle, 2000 (Stromboli On-Line, http://stromboli.net). 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.

Photo by Karoly Nemeth, 2005 (Massey University). The 4-5-km-diameter Mere Lava volcano is shown in this 14 March 2021 Planet Scope satellite image (N is at the top). It has a distinct summit crater that has a scoria cone with its own summit crater inside. Erosion has formed radial valleys down the flanks.

Satellite image courtesy of Planet Labs Inc., 2021 (https://www.planet.com/). 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.

Photo by Royal New Zealand Air Force, 1977. 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.

Photo by Karoly Nemeth, 2005 (Massey University). 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.

Photo by J-M Bore, 1999 (Institut de Recherche pour le Développement, Vanuatu). 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.

Photo courtesy Geological Survey, New Hebrides, 1971. 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.

NASA International Space Station image ISS006-E-26739, 2003 (http://eol.jsc.nasa.gov/). 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.

Photo by P. Evin, 1995 (Institut de Recherche pour le Développement, Vanuatu; Bull. Global Volcanism Network, 1999). 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.

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. Garat is located within the 6 x 9 km wide caldera that is partially filled by Lake Letas. The northern caldera rim is in the background.

Photo by Claude Robin, 1991 (ORSTROM, Vanuatu). Motlav or Mota Lava island is part of the Vanuatu northern Banks Islands, shown in this April 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 12 km across). The NE-SW central ridge contains eroded late Pleistocene eruptive centers. Two younger cones are visible here, Tuntog near the center of this image and Vetman to the SW.

Satellite image courtesy of Planet Labs Inc., 2019 (https://www.planet.com/). 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.

Photo by Karoly Nemeth, 2005 (Massey University). 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.

Photo by John Seach, 1999. 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.

Photo by Michel Lardy, 1990 (ORSTROM, Vanuatu). 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.

Photo by Michel Lardy, 1998 (Institut de Recherche pour la Développment, Vanuatu). 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.

NASA International Space Station image ISS006-E-40036, 2003 (http://eol.jsc.nasa.gov/). 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.

Photo by Royal Air Force (published in Green and Short, 1971). 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.

Photo by Karoly Nemeth, 2005 (Massey University). 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.

NASA International Space Station image ISS006-E-5732, 2002 (http://eol.jsc.nasa.gov/). 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 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.

Photo by Ian Nairn, 1988 (New Zeland Geological Survey). A telephoto view looking approximately E from the crater rim on 4 December 2005 shows a Surtseyan eruption from Lake Voui, on Ambae volcano. This explosive eruption began in Lake Voui on 27 November and resulted in the formation of a new cone in the lake.

A dark cock’s-tail plume and a lighter gas-and-ash plume can be seen rising above the vent within the late. Three small islands that formed prior to this eruption can also be distinguished.

Photo by Philipson Bani, 2005 (Institut Recherche Développement, IRD). 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.

NASA International Space Station image ISS006-E-40035, 2003 (http://eol.jsc.nasa.gov/). 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.

A plume rises from the active crater of Mount Garat in this view across Lake Letas, within the 6 x 9 km summit caldera of Gaua volcano (also known as Santa Maria). Three craters are located at the top of Mount Garat. The onset of eruptive activity from a vent high on the SE flank in 1962 ended a long period of dormancy.

Photo by John Seach, 1999. 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.

Photo by Ian Nairn, 1988 (New Zealand Geological Survey). 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.
