Have you heard about the blue fire phenomenon? It is the result of a reaction of natural gas with oxygen at a certain temperature. A blue flame indicates safe and efficient combustion, meaning that the gas is being burned efficiently and not being wasted.
Where is there blue fire? You can see it on your gas stove or gas furnace, or any other gas appliance. But do you know that you can also find blue fire in nature? You can, but there are only 2 main places in the world where you can find it; in “Kawah Ijen Craters”, Indonesia and in Dallol mountain, Ethiopia. Sometimes you can also see it in the “Iceland Craters”.
The best time to visit Mount Ijen is during the dry season from July to September. In the rainy season is very dangerous to climb because the road is slippery. Blue flame can only be seen in the early morning at Ijen Crater, which is from 01:00 to 02:00, before sunrise. This bright color comes from the high temperature in the crater.
The Blue Fire phenomenon in “Kawah Ijen Craters” may have existed hundreds or even thousands of years ago.
In Ethiopia’s Danakil Depression, the sulfur dust in the soil of a hydrothermal vent ignites to form blue flames.
