Geological Background

The late-Plestocene to Holocene Bunyaruguru volcanic field, also known as the Kichwambe volcanic field, straddles the equator along the eastern side of the Western Rift Valley, south of Lake George. The Bunyaruguru volcanic field contains more than 130 maars, 27 of which contain lakes with water ranging from fresh to saline. Friable calcareous volcanic tuffs are inter-bedded with Pleistocene and Recent sediments. Only a few foiditic lava flows are found in the volcanic field. Although no dated eruptions are known, Reece (1955) noted that volcanic activity probably continued into historical times.

The Global Volcanism Program is not aware of any Holocene eruptions from Bunyaruguru. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Bunyaruguru 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.

Photo Gallery

Maars of the Bunyaruguru volcanic field, also known as the Kichwambe volcanic field, blanket the center of this NASA Landsat image (with north to the top) of the eastern side of the Western Rift Valley. The Bunyaruguru field, lying south of the river channel connecting Lake Edward (left-center) and Lake George (top right), contains more than 130 explosion craters, 27 of which contain lakes with water ranging from fresh to saline. Maars of the Katwe-Kikorongo volcanic field lie across the river channel at the upper left.
