The Bishoftu volcanic field, also known as Debre Zeit, consists of an area of fissure-fed Holocene lava flows, cinder cones, tuff rings, and maars. Several of the maars are filled by lakes, which are popular recreational destinations from the nearby capital city of Addis Ababa. Most of the craters and cones are aligned NE-SW, parallel to the direction of the Ethiopian Rift Valley. The 750 x 1000 m wide Haro Maja tuff ring and its neighbor, lake-filled Kilole, are offset to the east. The cones and maars of the Bishoftu volcanic field were erupted through rhyolitic welded tuffs.
