As night begins to fall across East Java, Indonesia, the color palette of the world grows more subdued. That is, except in one area, where one of the most spectacular shows on Earth is about to take place.
This is Kawah Ijen, a living volcano in eastern Java. It looks just like any other active volcano. That is to say: nothing grows on it, nor, if it can be helped, goes near it.
Yet there are people who often have to venture to the volcano, regardless of the danger it may cause. This is because of the hot vents around the volcano slope, which pump out sulfur – something that can be extracted and sold and which, as a result, can help earn locals a living.
