When we think of a volcano erupting, the shades that come to mind are usually a mix of molten orange-red-yellow, right? But guess what, the island nation of Indonesia that is overshadowed by active volcanoes, has a strangely beautiful volcano that erupts blue fire. Interesting, no?
Kawah Ijen volcano in Indonesia erupts electric-blue fire that can frequently be seen streaming down the mountain at night and the pictures are astonishingly beautiful.
Though, Paris-based photographer, Olivier Grunewald, who has been recording the Kawah Ijen volcano for numerous years says the blue glow isn’t lava, it is really the light from the combustion of sulfuric gases. Basically, when the gases emerge from the cracks of the volcano and come in contact with the oxygen-rich atmospheric air, they explode, giving rise to a blue flame.
Olivier Grunewald further describes that when some gases condense into liquid sulphur and continue to burn as it flows down the slopes, it gives us the illusion of lava flowing. Evidently, the blue hue is best seen at night, which is why, many holidaymakers make their way to the crater to see this strange phenomenon after sunset.
Grunewald took these fascinating photos without using any filters on them so what you see right now, is pure beauty at its best. Located within the crater, there also lies the world’s biggest known acidic crater lake which is filled with hydrochloric acid. In fact, its bluish-greenish color comes from a high intensity of dissolved metals.
The fumes from the volcano often react with the water resulting in a low pH of 0.5. But, when the gases cool down, they leave behind sulphur deposits around the lake as excess.
Here are some more breathtaking photos of the blue volcano lighting up the night skies in Indonesia.
So, if you are preparing to visit this volcano, don’t ignore to pack a gas mask and an eye protective gear, for your own safety.
