View of the immense, 2 km wide summit crater, a small caldera surrounded by steep walls 4-500 m deep. It reminds a lot of Nyiragongo. The recent eruption has covered the whole floor with fresh lava and built a large cinder cone in the SE part (view is from the north). (Photo: Tom Pfeiffer)
Bromo volcano photos: Bromo is one of Indonesia's most visited volcanoes. It is the most active vent inside the huge Tengger caldera and erupts every few years.
