The Bufumbira volcanic field in SW Uganda consists of a group of about 40 cinder cones lying north of the large stratovolcanoes of the NE part of the Virunga Mountains. The cinder cones occur in clusters and were erupted along lineaments. They are typically breached on one side by lava flows. Their age is not known precisely, but they are considered younger than the stratovolcanoes of the Virunga Range, some of which are Holocene in age. The Bufumbira rocks are noted for their unusual ultrapotassic chemistry.

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

The Global Volcanism Program has no synonyms or subfeatures listed for Bufumbira.

Cinder cones of the Bufumbira volcanic field in SW Uganda (center) lie north of the large stratovolcanoes of the NE part of the Virunga Mountains. The roughly 40 cinder cones occur in clusters and were erupted along lineaments; they are typically breached on one side by lava flows. The Bufumbira rocks are noted for their unusual ultrapotassic chemistry. Muhavura (center) and Sabinyo (left) stratovolcanoes are visible at the bottom of this Landsat image.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
