The Global Volcanism Program is not aware of any Holocene eruptions from Bratan. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Bratan page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Photo Gallery


The summit of Agung volcano marks the highest point on the island of Bali. The broad irregular volcanic massif in the far distance is the 11 x 6 km wide Bratan caldera in north-central Bali. Batukau, the largest of several post-caldera cones overtopping the southern rim, is the sharp peak at the left. Three lakes occupy the floor of Bratan caldera. Many of the cones are quite old, but some postdate the youngest dacitic pumice eruptions of Batur volcano (<23,000 years ago).

The Bratan volcanic complex is seen here from the east on the rim of Batur caldera. The peak at the right is Pengilangan, on the NE rim of a 11 x 6 km wide caldera cutting Bratan volcano. The caldera, which contains three lakes, lies between Pengilangan and the cluster of peaks at the left-center, which are post-caldera cones constructed over the south caldera rim. The sharp peak at the far left is Batukau, which lies south of the caldera. The flat-lying slopes in the foreground are underlain by pyroclastic-flow deposits from Batur caldera.

The Bratan volcanic complex in north-central Bali is seen here from the east along the road south of Batur volcano. The Bratan complex is cut by a 11 x 6 km wide caldera whose northern floor contains three lakes. Several post-caldera stratovolcanoes, such as Batukau, Sengajang, and Pohen (left to right) lie south of the caldera or straddle its southern rim. The cones are well-formed, but covered with thick soils and vegetation; they are thought to have been inactive for hundreds or thousands of years.
