Kawah Putih (means white crater) is situated on the top of Mount Patuha in South Bandung. The color of the crater is apple green because it contains sulfur.
Two craters adorn the summit of Patuha Volcano. The dry crater of Kawah Patuha lies 600 meters northwest of Kawah Putih, a crater lake with approximately 8 meters of water depth. Kawah Putih crater lake represents a relatively stable volcanic system, with no records of magmatic or phreatic activity since A.D. 1600. Nevertheless, magmatic activity manifests itself in Kawah Putih as the hyperacid lakewater solution that results from condensation of SO2, H2S, and HCl gases near the lake bottom.
