Adjacent volcanoes are located between the Zwai (Ziway) and Koka lakes on the floor of the rift valley (Di Paola 1973, 1977) and immediately NW of Chilallo Volcano, Arsi Zone, Oromia Region, Ethiopia.
Bora rises about 350 m above the rift floor and has a summit crater 1.5 km in diameter. Bericcio is about 500 m high and forms a more regular cone; it has a small summit crater.
