Kawah Ijen's Blue Flames: Sulfur Burning in Air

Kawah Ijen's Deceptive Blue Flames

The electric-blue flames erupting from Kawah Ijen aren't what they seem. The sight often mistaken for 'blue lava' are actually flames igniting from sulfur-rich volcanic gases. These fumes meet air and create the unique electric blue phenomenon. Sulfuric gases may look mesmerizing, but they emit toxic fumes that one must avoid being exposed to. Toxic sulfur rich volcanic gases are life threatening when inhaled, absorbed or digested. The people behind this account, Earth Signal, reminds us “it’s not lava exactly.” The phenomenon is a result of sulfur-rich volcanic gases igniting upon contact with air. The flame is mesmerizing. Any sightseer should know that the gases are “toxic” and “extremely dangerous.”

Consequences of Exposure

The danger of exposure is high with such volatile gases. The lack of oxygen can lead to brain damage, coma, or even death. Breathing the rough fumes can cause the following to happen. Sulfur dioxide gas is dangerous to the respiratory system as it is a lung irritant and can lead to the exacerbation of pre-existing conditions. Long-term exposure can lead to a myriad of respiratory problems such as wheezing, chest pain, chronic cough, and the long-term damage of your upper respiratory tract (nasal passages, vocal cords, etc.). The toxic gas may also prevent the movement of oxygen throughout the body, leading to a lack of oxygen in vital organs.

Sulfur-Rich Volcanic Gases: An Unfinished Puzzle

Scientists still don't fully understand the process behind the burning sulfur. The reason why the sulfur gases ignite upon contact with air is not clear. However, experts do know a few things for sure. Sulfur is a volatile compound and just like other volatile compounds, it ignites in the presence of oxygen. Avoiding the toxic gases is wise. The gases are toxic, extremely dangerous, and one should not approach without authorization. If you value your life, don’t approach the area without proper authorization. Avoid the area and seek assistance if there is any risk.
