Ankaratra volcano is located in central Madagascar. Fissure eruptions created a series of tectonic lakes.

Eruptions at Ankaratra volcano have formed extensive lava flows and cones of basalt, basinite and phonolite covering the Ankaratra plateau at elevations of 2300–2700 m.

The most active area of seismicity is beneath the Ankaratra plateau, where numerous minor earthquakes occur annually at depths of 15–28 km, including magnitude 5.2 and 5.5 events in 1985 and 1991.
