Volcanic sulphur mining. View of men carrying baskets of sulphur after taking it from deposits around a crater lake at Kawah Ijen volcano, Java, Indonesia. Elemental sulphur is produced around volcanoes as hot sulphur-containing gases from volcanic vents condense and form deposits when they contact the cooler air. Gas from a sulphurous vent can be seen rising behind the men. Crater lakes such as this one are formed when a giant volcanic eruption leaves a crater which becomes filled with water. The water is typically hot, highly acidic and rich in sediment, which leads to its vivid colouration.
