Blue Fire Crater: Rivers of Molten Sulphur Flowing Inside an Indonesian Volcano Photographed by Reuben Wu

While on a trip to visit the Ijen and Bromo Tengger Semeru volcanoes in East Java last month, Chicago-based photographer Reuben Wu captured the unusual sight of molten sulphur that flows from fumaroles at the base of the Blue Fire Crater at Ijen. The area is usually swarming with tourists, but Wu stayed after sunset until the moon rose to capture these otherworldly images.
