An aerial view from the NNW shows the two summit craters of Gunung Patuha volcano in the foreground. Steep-walled Taman Saat crater (left) is located NW of lake-filled Kawah Putih (right). The dashed circle at the middle left indicates an unvegetated area called the “Tugeslibde crater.”

The forested andesitic Gunung Patuha rises SW of the plain of Bandung in western Java. Patuha is the northern peak of a roughly 5-km-long N-S volcanic massif, and has a 300 m crater at the summit. A few hundred meters down the SE flank is a 400 x 500 m crater almost completely filled with a shallow greenish lake, Kawah Putih. Sulfur deposits are present around the shoreline and near active fumaroles on the crater walls. A large debris-avalanche deposit extends down the NE flank. The volcano was formed during the late Pleistocene, but no Holocene eruptions are known.
