Tengger caldera is about 16 km wide and 500 m deep. Seven eruptive centers are on the floor of the flat-bottomed Sandsea caldera, the youngest at the compound Tengger caldera. The cluster of post-caldera cones was constructed along E-W and NNE-SSW fracture zones. Bromo is the active cone in this view from the south. Bromo crater is around 600 x 700 m and contains a terrace indicating the migration of its eruptive center to the north.
