The Neon blue volcano

We've all seen  volcanoes, but this Indonesian miracle goes beyond our wildest expectations. Kawah Ijen is an amazing natural phenomenon , because his flame is blue and makes it seem like a fairy tale " hero ."

This natural phenomenon is located in East Java, Indonesia and when it burns people watch in fascination, rather than run away from it. This is because at the bottom there is a lake of sulfur and gas having a temperature of up 600 ° C in the blaze blue tint. Some of the compounds remain liquid and continue to flow around the neck of the volcano. Kawah Ijen is used for the extraction of sulfur and there are  miners who toil tirelessly giving more pieces of solidified sulfur hands of dangerous place . They carry an average of about 90 pounds per day, per kilogram traded for about 5 cents.

Photographer O.Grunewald captured the scene, along with a group of men who toil on the volcano at night, battling noxious gases to mine sulfur from the crater and carry it out by hand. The volcano is the subject of a new documentary - produced by Grunewald and Régis Etienne, the president of Geneva's Society of Volcanology.
