Mount Sempu in the northern arm of Sulawesi, Indonesia, contains a 3 km wide of caldera. A maar, called Kawah Masem, was formed in the south-west of the caldera and contains a crater lake. Sulfur deposits have been extracted from the maar since 1938. Historical records, however, are unknown from the volcano.
