Kawah Ijen, le Mystère des Flammes Bleues plot
The Indonesian volcano Kawah Ijen emits neon blue lava, which produces beautiful images. The volcano contains a lot of pure sulfur, which turns a bright blue-violet color when it burns. The blue flames can grow up to five meters high. Photographer Olivier Grunewald went on site to capture the fascinating spectacle.
