Bromo volcano produces a gas-and-steam plume at the left in this view from the rim of Ngadisari caldera, the older of two Tengger calderas. Bromo and Batok in the lower center are two of several post-caldera cones within the caldera. The towering peak of Semeru appears in the background at the end of a N-S trending volcanic massif.
