Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Butajiri-Silti Field

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. Photo by Giday Wolde-Gabriel (Los Alamos National Laboratory).
