Steam rises from Bromo, a post-caldera cone of the Tengger caldera, seen here from Semeru volcano to the south. The ridge in the background is the outer wall of the 16-km-wide Ngadisari caldera. Bromo, the source of all historical eruptions at Tengger caldera, is one of several post-collapse cones constructed within the younger Tengger (Sandsea) caldera.
