There are several volcanos located in Indonesia. Kawah Ijen is one of them that is a very unique volcano because of the color of the gases that it burns. When high pressure and temperatures reach over 1100 degrees fahrenheit, the blue gas sends flames 16 feet high.
The blue lava can be seen from a distance.
Some of the gases condense into liquid sulfur, and continues to burn as it flows down the slopes giving the feeling of blue lava flowing.
Because the sulphuric gases are mined for sulphur, local miners trap the gases through ceramic pipes, resulting in condensation of molten sulfur.
The sulfur, which is deep red in color when molten, pours slowly from the ends of these pipes and pools on the ground, turning bright yellow as it cools.
The miners break the cooled material into large pieces and carry it away in baskets to a nearby refinery. A worker can earn up to $13 dollars a day in this way.
The workers work in extremely hazardous condition with insufficient protection. Most of them suffers from numerous respiratory problems due to breathing toxic fumes day in and out.
At night the hot gases burn to emit an eerie blue glow that is unique to Kawah Ijen.
The caldera of Kawah Ijen harbors a kilometer-wide, turquoise colored, acidic crater lake that leaks sulphurous gases constantly.
The wonders of the Earth seriously amaze me. This volcano is so breath-taking, even though it would be very dangerous to be around.
