The modern Rajabasa edifice is composed of two edifices, the Rajabasa and Balerang cones, that formed within a 25-km-diameter caldera at the SSE tip of Sumatra Island. The complex is shown in this May 2019 Planet Labs satellite image monthly mosaic (N is at the top; the image is approximately 12 km across). The flanks are formed by lava flows erupted from the summit and flank vents, and flank collapse events have resulted in horseshoe-shaped scarps.
