Itasy volcanic field
Volcanic field in Madagascar
The Itasy volcanic field is a monogenetic volcanic field west of Lake Itasy in the Itasy Region of central Madagascar. It consists of a north–south trending group of lava domes, scoria cones and maars, as well as lava flows with varying compositions. Volcanism in the Itasy field began during the Pliocene with the eruption of trachytic lava domes and basanitic lava flows.
