Volcanoes of Solomon Islands (16)

Coleman Seamount | Cook | Gallego | Kana Keoki | Kavachi | Kolombangara | Maetambe | Mbareke | Nggatokae | Nonda | Rendova | Savo | Simbo | Tinakula | unnamed | Vangunu
The volcanoes of the Solomon Islands form a NW-SW trending island chain continuing the Bougainvilla Island chain (which belongs to Papua New Guinea). The islands belong to a volcanic arc caused by the subduction of the oceanic crust of the small Solomon Plate under the Pacific Plate.
The area is a tectonically complex, marked by the interaction of several closely spaced oceanic microplates separated by subduction zones and short spreading centers, such as one extending from SE New Guinea to Kavachi volcano.

Coleman Seamount

(submarine volcano unknown depth)
Coleman Seamount volcano is a submarine volcano in the western Solomon Islands discovered in 1985 by the Hawaiian "Moana Wave" research vessel during a November 1985 to January 1986 cruise. [more]

Cook

(submarine volcano unknown depth)
Cook volcano is an alleged active submarine volcano in the Western Solomons, whose existence is questionable and not accepted by Smithsonian's Global Volcanism database, although it is listed as one of the 4 active volcanoes (Savo, Kavachi, Cook and Tinakula) of the Solomon Islan... [more]

Gallego

(volcanic field 1000 m / 3,281 ft)
Gallego volcano is a group of eroded cones covering a large part of the NW end of Guadalcanal Island. Mount Esperance, a small but well-preserved andesitic cone is said by to have been active less than 2000 years ago, according to local traditions. It is possible, however that th... [more]

Kana Keoki

(submarine volcano -700 m / -2,297 ft)
Kana Keoki is an active submarine volcano in the Western Solomons, located 26 km SW of Rendova Island.
Studies from the 1960s have shown that the dacitic volcano is an active volcano, that forms a 3000 m high seamount on the Ghizo Ridge south of the plate margin between the... [more]

Kavachi

Kavachi volcano is a shallow submarine volcano located south of the remote Vangunu Island in the Solomones. It is als known as Rejo te Kvachi, "Kavachi's Oven", and one of the most active of the Pacific with near surface eruptions every few years that often build temporary island... [more]

Kolombangara (also spelled Kulambangara) is a possibly active stratovolcano that forms the almost perfectly round, 15 km diameter Kolombangara Island in the New Georgia Islands group of the Solomon Islands.
Its name in local language roughly translated to "Water Lord", ref... [more]

Maetambe

(Unknown 960 m / 3150 ft)

Mbareke

(Stratovolcano 500 m / 1640 ft)

Nonda

(stratovolcano 760+ m / 2,493 ft)
Vella Lavella Island (left center) in the New Georgia Islands in the Solomon Islands chain. North lies to the upper left in this NASA Space Shuttle image. Nonda volcano, the youngest volcanic feature of Vella Lavella Island, is a lava dome located within a well-preserved crater in the northern part of the island. The Paraso thermal area, the small light-colored area at the upper left-center portion of the island, displays solfataras, hot springs, and boiling mud pots. Kolombangara Island is at the upper right. (NASA Space Shuttle image ISS002-727A-2, 2001)

Nonda volcano is an andesitic stratovolcano on Vella Lavella Island in the Solomon Islands. Its lava dome inside a well-preserved crater is the youngest volcanic edifice on the island.
There are no confirmed historical eruptions, but inhabitants reported "smoke" and explos... [more]

Rendova

(Stratovolcano 1050 m / 3445 ft)
[more]

Savo

(stratovolcano 485 m / 1,591 ft)
Savo volcano is a forested andesitic to dacitic stratovolcano that forms the 6x7 km wide Savo Island, located 14 km north of Guadalcanal.
The volcano contains a shallow, elliptical 1x1.5 km wide summit crater.
Savo volcano has had dangerous explosive eruptions in th... [more]

Simbo

(stratovolcanoes 335 m / 1,099 ft)
Simbo volcano forms the small Simbo Island located in the Western Solomons about 31 km SW of Ghizo. The volcano last erupted sometime between 1900 and 1920, based on oral traditions.
Simbo Island is famous for its head-hunter tribe discovered in the 19th century. This unple... [more]

Tinakula

Tinakula volcano is located at the NW end of the Santa Cruz islands in the Solomon Islands. It forms a small 3.5 km wide and steep island, which is the upper 25% of a very active stratovolcano that rises more than 3 km from the sea floor. Tinakula is very similar to more]

unnamed

(submarine volcano -240 m / -787 ft)
An unnamed submarine volcano is located 7 km NW of Kavachi volcano and might belong to the same magmatic system, i.e. represent a second vent of the same volcano.
In 1992 thermal plumes were detected from one of its 2 summit craters. [more]
