Background
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 lava domes and basanitic lava flows. Later activity produced trachytic lava flows and recent vulcanian eruptions. A trachytic maar was formed near Saovinandriana at the beginning of the Holocene, and several other crater lakes are present. Mild seismicity and thermal activity in the form of hot springs continues at Itasy.---
