Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Bufumbira

Scoria cones of the Bufumbira volcanic field in SW Uganda (center) lie N of the large stratovolcanoes of the NE part of the Virunga Mountains. The roughly 40 scoria cones occur in clusters and were erupted along lineaments and 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.
