Extensive area SE of Addis Ababa is wholly occupied by volcanic rocks that fall into 4 main categories (Gasparon et al. 1993): early basalts; trachytic and rhyolitic ignimbrites with minor intermediate flows and domes; central volcanoes (Yerer, Bede Gebade, Zikwala); youngest are basaltic lavas, spatter and cinder cones and maars with which are also associated intermediate and silicic rocks.

Approx coords range: 8º20' - 9º00'N; 38º55' - 39º15'E.
