Kawah Ijen: The Hell of Sulfur

In Indonesia, Kawah Ijen reveals its infernal insides. Miners extracting sulfur work in extreme conditions, and take turns daily in the inferno of the crater. One of the workers, Sarno, has been working there for twenty-eight years. Under such severe conditions, he would extract sulfur with a mining bar and carry 75 kilos of it on his back. Sum Arti, a volcanologist, monitors the level of danger linked to gases and protects miners from the risk of gas bubbles that can potentially be lethal.
