ndonesia’s Kawah Ijen Volcano, glows with an almost otherworldly neon blue at night. The mountain contains large amounts of pure sulfur, which emits an icy violet color as it burns, turning the rocky slopes into a hot (at least 239 degrees Fahrenheit), highly toxic environment.
Despite the danger, photographers and others are lured to this breathtaking scene for a chance to capture it on film.
While on a trip to East Java in Indonesia this past July, Chicago-based photographer, music producer, and filmmaker Reuben Wu took some rather stunning images of the intensely blue molten sulphur gushing from fumaroles in the base of the Blue Fire Crater at the Kawah Ijen volcano.
