About Ijen Volcano
West of Gunung Merapi is the Ijen volcano, which has a one-kilometer-wide turquoise-colored acidic crater lake. The lake is the site of a labor-intensive sulfur mining operation. The work is paid well but it is very onerous. Workers earn around ($5.50–$8.30) Rp 50,000–75,000 per day and once out of the crater, still need to carry their loads of sulfur chunks about three kilometers to the nearby Paltuding Valley to get paid.
Kawah Ijen has a diameter of 722 meters and a surface area of 0.41 square kilometers. It is 200 meters deep and has a volume of 36 cubic hectometres.
Sulfur Acid Kawah Ijen
Kawah Ijen is recognized as the largest highly acidic crater lake in the world. On July 2008, National Geographic explorer George Kourounis took a small rubber boat out onto the acid lake to measure its acidity. The pH of the water in the lake’s edges was measured to be 0.5 and in the middle of the lake 0.13 due to high sulfuric acid concentration.
