Kawah Putih lake (7.10° S 107.24° E) is one of the two craters which make up Mount Patuha, an andesitic stratovolcano (a “composite” volcano). Mt Patuha is one of numerous volcanoes in Java, Indonesia. Kawah Putih crater lake itself represents a relatively stable volcanic system with no records of significant activity since around 1600.
