Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Vakinankaratra
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.

The Quaternary Vakinankaratra volcanic field is at the SW end of the Neogene Ankaratra volcanic field. The larger field covers a 100-km-long area in central Madagascar generally between Avironimamo to the N and Antsirabe to the S. Trachytic lava domes were erupted during the initial stage, and massive fissure eruptions created a series of tectonic lakes. The latest activity produced well-preserved basanitic cinder cones. Vulcanian eruptions formed several lake-filled craters.
