BLUE FLAMES OF ACID VOLCANO LAKE

JVD WORLD TRAVELERS: BLUE FIRE IJEN CRATER - Java, Indonesia
The Ijen volcano complex is a group of composite volcanoes located in East Java, Indonesia. It is known for its blue fire, acidic crater lake, and labour-intensive sulfur mining.
It is inside an eponymous larger caldera Ijen, which is about 20 kilometres wide. The Gunung Merapi stratovolcano is the highest point of that complex. The name Gunung Merapi means mountain of fire in the Indonesian language.
West of Gunung Merapi is the Ijen volcano, which has a one-kilometre-wide turquoise-coloured acidic crater lake. The lake is the site of a labour-intensive sulfur mining operation, in which sulfur-laden baskets are carried by hand from the crater floor. The work is paid well considering the cost of living in the area, but is very onerous. Workers earn around US$13 per day. The active crater at Kawah Ijen has a diameter of 722 metres and a surface area of 0.41 square kilometres. It is 200 metres deep and has a volume of 36 cubic hectometres.
The lake is recognised as the largest highly acidic crater lake in the world. The pH of the water at the lake's edges was measured to be 0.5 and in the middle of The blue fire is ignited sulfuric gas, which emerges from cracks at temperatures up to 600 °C. The flames can be up to five meters high; some of the gas condenses to liquid and is still ignitedthe lake 0.13 due to a high concentration of sulfuric acid.
The blue fire is ignited sulfuric gas, which emerges from cracks at temperatures up to 600 °C. The flames can be up to five meters high; some of the gas condenses to liquid and is still ignited.
Ijen is the largest blue flame area in the world. Local people refer to it as Api Biru (Blue Fire). The other location at which blue fire can be seen is in Dallol Mountain, Ethiopia.
The sulfur, which is deep red when molten, pours slowly from the ends of these pipes and pools on the ground, turning bright yellow as it cools. The miners break the cooled material into large pieces and carry it away in baskets. Miners carry loads ranging from 75 to 90 kilograms up 300 metres to the crater rim, with a gradient of 45 to 60 degrees, and then 3 kilometres down the mountain for weighing. Most miners make this journey twice a day.
A nearby sulfur refinery pays the miners by the weight of sulfur transported; as of September 2010, the typical daily earnings were equivalent to approximately $13 US. The miners often receive insufficient protection while working around the volcano and complain of numerous respiratory afflictions. There are 200 miners, who extract 14 tons per day — about 20% of the continuous daily deposit.
