Butajiri-Silti Field

Volcanic field · Ethiopia · 2281m

The 1-km-wide, lake-filled Ara-Shetan maar is located at the S end of the Butajiri-Silti volcanic field. It consists of a large group of basaltic scoria cones, maars, and lava flows in an 80-km-long, NE-SW-trending area near the W margin of the Ethiopian Rift. At least 13 maars, many filled by lakes, are located near the town of Debre Zeit, SE of Ethiopia's capital city, Addis Ababa.

Geological summary

The Butajiri-Silti volcanic field consists of a large group of basaltic cinder cones, maars, and lava flows in an 80-km-long, NE-SW-trending area near the western margin of the Ethiopian Rift. At least 13 maars, many filled by lakes, are located near the town of Debre Zeit, SE of the capital city of Addis Ababa. The maars were erupted through Pleistocene rhyolitic lava flows and tuffs. Eruptions of the younger basaltic cinder cones were contemporaneous with those that produced the maars. Some of the lava flows associated with the cinder cones were considered very young by Di Paola (1972).
