Though in strict sense this cant be called a lava, Kawah Ijen spouts this beautiful sight to behold.
Luckily, Chicago-based photographer Reuben Wu was there to photograph it.
He explains that the electric blue glow is brought on by a combustion of sulfuric gases.

So, in reality, it is liquid sulfur that is responsible for such a beautiful spectacle.
The base of Kawah Ijen from which the gases emerge is called the Blue Fire Crater.
Grunewald says that Kawah Ijen itself is just one volcano within a larger Ijen volcano complex.

They are contained within a caldera, an area of land that has collapsed due to previous volcanic eruption.
The Ijen caldera is huge, at about 12.5 miles wide.
Apparently, the electric blue liquid sulfur of Kawah Ijen isnt any secret any longer.

Ever since it was made famous by the National Geographic, Kawah Ijen has been flocked by tourists.
