Photos of the Glowing Sulfur Inside Indonesia’s Blue Fire Volcano Crater
The Ijen group of volcanoes in East Java, Indonesia, features a popular tourist destination called the Blue Fire Crater. Molten sulfur and sulfuric gas emerge from cracks in the crater, causing large blue flames and streams of glowing blue “lava.”
Chicago-based photographer Reuben Wu visited the volcano last month, capturing both its majesty from afar and its mesmerizing blue flows from up close.
It’s a two hour hike to get to the rim of the crater, and then another 45-minute hike to get down to the bank. Sulfur gas in the crater is ignited by temperatures that reach 1,112° F (600° C).
You can find more photos from this series here, and more work by Wu on his website.
