At the southern end of the island are old stratovolcano cones, Monte Aria (), Monte Saraceno () and Monte Luccia (), which have partially collapsed into the Il Piano Caldera.
The most recently active centre is the Gran Cratere at the top of the Fossa cone, the cone having grown in the Lentia Caldera in the middle of the island, and has had at least 9 major eruptions in the last 6000 years.
