The sulfur on the crater in Indonesia is heated, creating a magical blue fire.
Blue flames appear on the crater of Kawah ljen, in the eastern province of Java, Indonesia, instead of red as the usual craters.Kawah ljen crater is also known as death pit with sulfur deposit above.
The phenomenon of blue fire on the crater is clearly observed when daylight fades.
Sulfur on the crater is heated at high temperatures and forms large flames of mysterious blue.
These fires can lift as high as 5m and shine a wide area, especially at night.When burning, sulfur will emit sulfur dioxide causing suffocating feeling.
Many people living around the area came to the volcano to exploit sulfur for more than 40 years.In order to supplement the small collection, they often come here to exploit at night and thanks to the light emitted from these flames.
For those who work in volcanic sulfur mining, this is a dangerous work to their health and life.
