Geological Summary

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.

The Global Volcanism Program is not aware of any Holocene eruptions from Bishoftu Volcanic Field. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Bishoftu Volcanic Field page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

A chain of lake-filled maars (dark-colored in this Landsat image), tuff rings, and cinder cones, lies along the Ethiopian Rift Valley SE of Addis Ababa and forms the Bishoftu volcanic field. The city of Debre Zeit (left-center) lies between two maars, irregular-shaped Lake Hora and circular Lake Bishoftu. The Haro Maja tuff ring and its neighbor to the west, lake-filled Kilole maar (upper right), are offset to the east.
