Burning Blue: Indonesia’s Psychedelic Sulphur Volcano

A FLAMING hot volcano glows in the dark as its sulphuric gases burn sapphire blue. Filmed at the Kawah Ijen volcano in east Java, Indonesia, this rare phenomenon was captured by volcano explorer Marc Szeglat. Shot in August, the German videographer was able to film the haunting blue flames which are caused by the combustion of sulphuric gases which billow through vents at burning hot temperatures. Some of the gases then condense into liquid sulphur which continues to burn creating the blue fire which can only be captured during the darkness of night.
