Tullu Moje has produced both mafic and silicic eruptions, with silicic volcanism emplacing explosive deposits and thick obsidian lava flows, like the flow in the center of this 5 December 2019 Sentinel-2 satellite image (N is at the top; this image is approximately 11 km across). Immediately south of the flow is the Tullu Moje cone with a roughly 700-m-wide crater. The suspected Tullu Moje caldera is south of the Gedamsa caldera.
