The mesmerizing sulfur-induced blue flames of Indonesia’s Mount Ijen attract hundreds of tourists every night, but mask one of the most dangerous jobs in the world: sulfur mining.

Sulphur-induced blue flames are nothing more than a mining by-product, but they have turned Indonesia’s Mount Ijen into a popular tourist attraction. Lured in by the magical phenomenon, I joined a tour group and hiked up the volcano in the hopes of getting a glimpse of the beautiful fire. But the shocking truth of what I discovered was far from magical. Sulfur miners were working in the crater. Slaving away among the fire and smoke, they wore no special clothing nor eye protection. Some did not even have gas masks. Watching the men was heart-rending, and made the blue flames seem completely insignificant. The reality of Mount Ijen is that sulfur miners work everyday in the most unforgiving environment in the world.

Mount Ijen, in Indonesia, is an active volcano situated on East Java, the closest island to the holiday-maker hotspot of Bali. Possessing unique characteristics, the views at Mount Ijen are otherworldly. The volcanic crater holds the largest highly acidic lake in the world, which beams with a vibrant, almost inviting turquoise blue. Above the lake are vivid yellow rocks that have been stained as a result of sulfur gasses condensing.

While spectacular to see, many dangers lurk in the volcano. Aside from the unpredictable volcanic eruptions, earthquakes are common and have been known to cause landslides in the crater. There was even an earthquake in 2020 that triggered a seiche-type tsunami in the acid lake. The seismic activity caused the mountain to belch poison gas and generated a three-meter wave that swept across the crater,, killing a sulfur miner.

Despite these dangers, the sulfur has drawn miners to the volcano since 1968 and has become a trade passed down through families ever since. Known locally as the ‘devil’s gold’, it is considered a commodity worth high risk. Not only do miners risk a quick death while mining, but they also experience long-term health issues and have an average life expectancy of just 50 years old.

In the dead of night, when the air is at its coolest, sulfur extraction commences. Miners start by hiking the 2000 feet incline, the equivalent of two eiffel towers, before descending into the crater. At this point, the sulfuric smell of rotten egg takes over, making it hard to breathe. Pipes that travel below the surface provide access to the sulfur. The miners use fire to heat the ground, causing the sulfur to liquidize and trickle through the pipework onto the ground outside. Left to cool and dry, the ‘devil’s gold’ takes shape in the form of rich, yellow crystalized rocks.

During the heating process, large clouds of harmful gas burst out from beneath the arid, rocky terrain. Each thick, opaque cloud swallows everything in its path, causing a complete whiteout. Unable to see even one meter in front of them, miners are left sightless until the miasma disperse. The atmosphere was so harsh that my throat tightened up and I was coughing after just 10 minutes in the crater. Daily exposure to these toxic fumes leaves miners with life-long respiratory issues. One miner, Udi, explained to me that his own father became blind due to repeated exposure to the fumes and, despite seeing the suffering in his family, has no choice but to follow the same line of work. 

Once the sulfur has been processed, it must be carried out of the volcanic crater. A steep path consisting of unsteady rocks is the only way out and, with no technology to aid in their efforts, miners must physically transport every piece of the precious material. They precariously balance up to 170 pounds of sulfur, more than their bodyweight, on their handmade shoulder carriers. Without proper back support, miners suffer back problems and often swelling in the shoulders.

Sulfur produced at Mount Ijen is sold on and used in a variety of products including detergents and cosmetics, and is even used to whiten sugar. According to Udi, one kilogram of sulfur is sold for 1000 Indonesian Rupiah ($0.065). If a miner sells a full load of sulfur that may have taken all night to produce, he will make 75,000 Rupiah (approximately $5). Surprisingly, this makes sulfur mining one of the better paid jobs in this remote area of Java. With high poverty rates, it is clear why locals risk their lives to sustain a livelihood.

The shocking reality is that local men are putting their lives on the line for what most in the West would consider pocket money. Witnessing them work tirelessly in the most inhumane conditions is an inconceivable sight, yet has become a spectacle for tourists to gawk at. The promise of stunning blue flames may sound alluring, but in truth Mount Ijen is a merciless place that no one should have to call work.

In 2017, Ijen Assistance raised $15,000 for relief work in the region from a music video following Bas, a sulfur miner, and his family.

TO GET INVOLVED

Providing aid after natural disasters, Islamic Relief has been working in Indonesia since 2000. After the earthquakes of 2006 and 2009, the organization responded immediately, distributing emergency supplies and later rebuilding a hospital and school. They also work to reduce the effects of poverty and have a variety of development projects across Indonesia.

Currently, there are no organizations working directly to improve the conditions for sulfur miners at Mount Ijen. Despite previous campaigns raising awareness and money, such as the ‘Terraform’ music video, miners continue to work in the same harsh conditions.
