Ijen Volcano Photos (East-Java, Indonesia)

Ijen volcano in East Java is famous for its acid crater lake and the large sulfur deposits that form around very active fumaroles near the lake shore.
The sulfur in the crater is being mined. At night, some of the fumaroles are on fire, with intense bluish flames from burning sulfur. Partially, this is due to auto-ignition due to very high temperatures at the fumarole vents, but mostly because the workers set fire to the sulfur n order to melt it and collect it from the frozen puddles that then form on the ground below.

Our expedition leader Andi visited Ijen crater during a period of elevated activity in May 2012, when lots of sulfur from the fumaroles was burning at night with blue and reddish flames, creating abstract photos.
The other photos are by our friends Jorge and Jessy who visited the volcano about 2 months later and give an impression of the volcano, known for its turquoise acid crater lake and the extensive sulfur mining. (Photo: Andi Rosadi)
