East Java’s blue lava spectacle

BRILLIANT blue flames light up the night sky above Kawah Ijen, casting an eerie electric glow as they flow down the sides of the active volcano in remote Indonesia.

Hot sulphuric gases – escaping at high pressure through cracks in the mountain – ignite upon contact with air, burning a fantastic, iridescent blue. This strange natural phenomenon can also create “blue lava” – rivers of burning liquid sulphur that stream from the vast crater.
