Gagak (Volcano): Gagak belongs to the Perbakti-Gagak or Kiaraberes-Gagak volcanic complex near Bogor, immediately SW of Salak volcano.
The 3 volcanoes of the group are, from S to N, Gunung Endut (1474 m), Gunung Perbakti (1699 m), and Gunung Gagak (1511 m).
Gunung Gagak lies to the NW of the group and is known for its large pumice and obsidian deposit at the summit, and obsidian lava flows extending to the north and NE.
Galeras (Volcano): Galeras is one of Colombia's most active volcanoes. In an eruption in 1993, it killed a group of scientists and tourists who had been inside its crater when it erupted. Read all
Galunggung (Volcano): Galunggung volcano about 100 km SE of West Java's capital Bandung had its last major eruption in 1982, when ash plumes reached 20 km. Read all
Gamalama (Volcano): Gamalama (Peak of Ternate) is a near-perfect conical stratovolcano that forms the entire island of Ternate off the western coast of Halmahera. It is one of Indonesia's most active volcanoes. Read all
Garibaldi (Volcano): Mt Garibaldi volcano at the head of Howe Sound, 66 km north of Vancouver in SW British Columbia is probably Canada's best-known volcano and part of the active Cascades Range. It is a young stratovolcano capped by a complex of lava domes. Its most recent eruptions occurred at the Opal Cone on the SE flank ca. 8000 years ago and produced the Ring Creek lava flow. Read all
Gaua (Volcano): Gaua is one of the most remote and most active volcanoes of the Vanuatu archipel, located on the island with the same name in the West Banks island group atht enorthern end of the archipelago. Its most recent eruption started in Sep 2009 from Mt Garet inside the caldera lake and is ongoing (as of April 2010). Read all

Ghegam (Volcano): The Ghegam Ridge, located in west-central Armenia between the capital city of Yerevan and Lake Sevan, contains a broad concentration of lava domes and pyroclastic cones of Pleistocene-to-Holocene age. Read all
Gilbanta (Volcano): Gilbanta (also spelled Gilibanta) is a submarine volcano off the western coast of Komodo Island. There are vague reports suggesting activity in 1957. Read all
Girekol (Volcano): A huge volcano north of Van lake with a great eruption crater towards south-east. Read all
Glacier Peak (Volcano): Glacier Peak is a stratovolcano in northern Washington and the most remote of the Cascade volcanoes. Its name comes from the 11 glaciers on its flanks.
Although it reaches more than 10,000 feet elevation, the volcanic edifice is only 500-1000 m high, because the volcano's base is located on a high ridge. Read all
Golden Trout Creek (Volcano): The Golden Trout Creek volcanic field consists of a group of cinder cones and lava flows in the Toowa Toowa valley of the Sierra Nevada, California, about 25 km south of Mount Whitney.
Toowa valley is a broad and open valley about 8600 feet high, dotted with cones rising 100-200 m above the valley floor. 4 volcanic centers have been identified at the Golden Trout Creek volcanic field. Read all

Gorely (Volcano): Gorely volcano is one of the most active volcanoes in southern Kamchatka and located 75 km SW of Petropavlovsk. It is a complex of several overlapping stratovolcanoes with many summit and flank craters. Activity in historic times were mainly small to medium-sized ash and steam eruptions. Read all
Graciosa (Volcano): The SE end of Graciosa, the northernmost of the central Azorean islands, contains a small 0.9 x 1.6 km caldera with active fumaroles. Read all
Gran Canaria (Volcano): The largely Miocene-to-Pliocene island of Gran Canaria in the middle of the Canary archipelago has been strongly eroded into steep-walled radial gorges called barrancos. Read all

Gunung Api (Volcano): Banda Api volcano forms a small isolated 3-km-wide island in the Banda Sea, Indonesia, 130 km south of Makulu Island. The volcano rises 4000 m from the sea floor and is the most recent and very active cone of a 7 km wide volcanic caldera mostly under water.
It is one of the most active volcanoes in the region and is known for violent activity including tall ash emissions, lava fountaining, strombolian explosions and occasional lava flows, some of which which have reached the sea. Because of its (for Indonesia) unusually effusive behavior and frequent activity, Banda Api has also been given the nickname "Etna of the Banda Sea". Read all
Gunung Api Wetar (Volcano): Gunung Api Wetar (Gunung Api = Fire Mountain) volcano forms a small round island in an isolated location in the Banda Sea, Indonesia. The volcano is a massive stratovolcano, rising 5 km from the sea floor; the island is just the uppermost 282 m above water. It is built from lava flows and has a central crater with an intra-crater cone. The slopes of Gunung Api show evidence of 3 large landslides, the largest of which forms en embayment on the NE coast.
The youngest lava flow descended the SW flank to the coast. Explosive eruptions in 1512 and 1699 are the only known historical activity of Gunung Api Wetar.
Gunung Semuning (Ranau caldera) (Volcano): Ranau is an 8 x 13 km caldera volcano in southern Sumatra partially filled by the crescent-shaped Lake Ranau. Gunung Semuning is a potentially still active stratovolcano constructed at the SE side of the caldera. Read all
