The 15-km-wide Corbetti caldera overlaps the NW margin of the older 30 x 40 km Awasa caldera. Urji volcano was subsequently constructed in the center of Corbetti caldera, which also contains young lava flows. Chabbi volcano, a large obsidian dome that grew on the SE caldera rim, has erupted lava flows onto the caldera floor. The age of the latest eruptive activity at Corbetti caldera is not known, although many lava flows are too young to date by the Potassium-Argon method. Fumarolic activity continues at the post-caldera cones of Urji, Chabbi, and an unnamed pyroclastic cone on the west rim.
