Madagascar Volcanoes - Global Volcanism Program
Chronological listing of known Holocene eruptions (confirmed or uncertain) from volcanoes in Madagascar. Bolded eruptions indicate continuing activity.
Vakinankaratra - Global Volcanism Program
The Ankaratra volcanic field in central Madagascar consists of lava domes, fissure vents, scoria cones, and maars. The volcanic field is one of the largest on the island and covers a 100-km-long area in central Madagascar. Hot springs occur at Ranomafana. N is at the top in this NASA Landsat image.
Itasy Volcanic Field - Global Volcanism Program
The Itasy volcanic field in central Madagascar contains a diverse assemblage of volcanic landforms, including scoria cones, lava domes, and maars. Activity began in the Pliocene and has continued into the Holocene. Early eruptions produced trachytic …
Nosy-Be - Global Volcanism Program
Nosy-Be island off the NW coast of Madagascar contains very recent basaltic lava flows from well-preserved cinder cones. Many large crater lakes are found in the central part of the island. A predominance of low-silica foiditic compositions overlie Mesozoic limestones and other sedimentary rocks.
Ambre-Bobaomby - Global Volcanism Program
The Ambre-Bobaomby volcanic field at the N tip of Madagascar consists of Miocene volcanics capped by very recent cones. The earliest volcanism produced a large basaltic massif and minor pyroclastic flows.
Ankaizina Field - Global Volcanism Program
The Ankaizina volcanic field, covering portions of the Tsaratanana and Ambondrona massifs in northern Madagascar, was active until the very recent Quaternary. An initial dominantly silicic phase included pyroclastic-flow formation and was accompanied by …
La Grille - Global Volcanism Program
Grand Comore Island in the Indian Ocean NW of Madagascar is formed by two massive shield volcanoes. The more well-known and historically active Karthala volcano at the southern end of the island has a 3 x 4 km summit caldera.
Volcanoes in the Somalian-Antarctic Volcanic Regions
Chronological listings of known Holocene eruptions (confirmed or uncertain) from volcanoes in the Somalian-Antarctic Volcanic Regions. Bolded eruptions indicate current continuing activity as of 17 October 2024.
Mayotte - Global Volcanism Program
Mayotte is a volcanic island in the Comoros archipelago between the eastern coast of Africa and the northern tip of Madagascar. A chain of basaltic volcanism began 10-20 million years ago and migrating W, making up four principal volcanic islands, according to the Institut de Physique du Globe de Paris (IPGP) and Cesca et al. (2020).
