Mount Bromo (Indonesian: Gunung Bromo),
is an active volcano and part of the Tengger Caldera, in East Java,
Indonesia. At 2,329 meters it is not the highest peak of the
massif, but it is the most well known.
Tengger caldera
The 16-km-wide Tengger caldera is located at the northern end of a
volcanic massif extending from Semeru volcano. The massive Tengger
volcanic complex dates back to about 820,000 years ago and consists
of five overlapping stratovolcanoes, each truncated by a caldera.
Lava domes, pyroclastic cones, and a maar occupy the flanks of the
massif. The Ngadisari caldera at the NE end of the complex formed
about 150,000 years ago and is now drained through the Sapikerep
valley. The most recent of the Tengger calderas is the 9 x 10 km
wide Sandsea caldera at the SW end of the complex, which formed
incrementally during the late Pleistocene and early Holocene. An
overlapping cluster of post-caldera cones was constructed on the
floor of the Sandsea caldera within the past several thousand
years. The youngest of these is Bromo, one of Java's most
active and most frequently visited volcanoes. The massif area is
one of the most popular tourist attractions in East Java,
Indonesia.
