Kawa Ijen's Blue Fire Volcano in Indonesia

Blue Flamed Ambassadors

The Blue Flame of Kawa Ijen is an enveloping sight. A volcanic landscape at night. The crater lake of Kawa Ijen, Indonesia, is a portal to this world, paranormal only in words. The comings and goings of blue flame from the ground serve as an ever present reminder of how we got here. “At night, bright electric blue flames appear across the volcano”. The volcanic lake's liquid fire is infamously known as the "blue flames". The extremely high temperature of the gases — over 600 degrees Celsius — creates the blue glow. The flames are not simply lava but gas. The gases are ignited when oxygen mixes with sulfur-rich gases released from deep underground.

Nature's Pyrotechnics

The blue flames of Kawa Ijen remain an extraordinary phenomenon. Indonesian volcanoes already have a reputation as key natural sites. After all, there are over 130 active ones in Indonesia. The blue fire doesn't change that. It does offer a colorful twist on life-threatening volcanic gases. The gas ignites blue when pools of sulfuric acid boil. These pools release sulfur-rich gas — the glowing blue fire. The fire goes out when the gases do. The burning sulfur flames eventually dim. These blue flames aren't blue when they reach temperatures of over 600 degrees Celsius. The flames burn when they come into contact with oxygen. The glowing blue fire is the outcome of sulfur gasses coming in touch with oxygen. The flames on Kawa Ijen could be considered a more hostile form of illumination than more conventional sources.

The Crater Lake’s otherworldly Appeal

A Pond of Smoke

The volcanic landscape moves from glowing blue flames to an altered state of the crater itself. Kawah Ijen crater lake is a jaw-dropping sight. The lake is filled with acidic water heated by the volcano’s fumaroles. The acidic makeup of the volcano's lake hels shape the ethereal flame in the sky. The acidity of the crater lake is a unique feature that sets it apart from others. The main reason that the lake holds 20,000 cubic meters of water. The lake is filled with the acidic water and once acidic enough it releases the blue flame. The acidic water of the volcano can alter ecosystems and damage plant and animal life. When the gas appears, the landscape becomes an otherworldly sanctuary. Amazing as it sounds, the glow comes from what is being called a chemical reaction of gasses.

Volcanic Tourism

Seeing the Blue

The volcano lagoon captivates adventures across the globe. The landscape of Kawa Ijen is a portal to something else. Seeing the blue flames in person is possible. The only entry point is the crater rim. The crater is known for its acidic water. A natural sulfuric acid mine thrives along the rim of the volcano. When visitors approach, they walk past and across the incredibly hot crater lake filled with pockets of blue fire.

Temporary Lodging

The fact that the landscape begins and ends with blue flames makes it an ideal place to rest. The crater rim becomes a place of rest. Tourists and travelers can also sleep in caves on the rim. Smoke from the lake below acts as a natural mosquito repellent. The view from the top of the gorge, and the volcano lake, injects tourists’ energy. The volcano gas is considered a breath of nature. The sulfur-rich smell of the gases is considered a reminder of the same. Different options for staying the night exist on the crater rim. But the most interesting place to stay is the hostel that has been converted from a sulfur mine.

Effect on humans

Blue flame sightings heighten the tourist experience. When the gas leaks out, it affects the area in ways that are difficult to predict. The sulfur-smoke produces horticultural benefits. These surroundings contain a near-existential threat. However, the blue flames are therefore only found above the surface of the water. The angry flames do not extend to the earth below. So resting above, or abstaining from the volcanic landscape, remains a safe practice. It is important to take the right precautions. Some visitors have described the flames as passing like a porch light, only staying for a moment, sometimes the flame doesn’t last long. Occasional blue flames make for truly epic moments. The acidic water of the volcano can alter ecosystems and damage plant and animal life. A gas mask is recommended for the acidic smoke. The gas mask comes with sulfuric acid extraction.

Blue Flames: Blessing or Curse?

Wildlife, rocks, and minerals are among the most commonly impacted elements. The volcanic effect is also used for farming. It changes the way the soil around it functions. The blue flames also produce sulfuric acid, which could lead to the destruction of ecosystems. Notes in some places describe how the lava can have high eruption rates. Within the crater, you can find not just the sulfur-rich gases. But also, ancient and recent lava flows. The acidic water is the reason this landscape can exist. The blue flames affect the way the surrounding terrain changes. Usually this involves how it impacts animal and ground life.

Playing with Fire (…or not)

Volcanic activity is a dangerous subject. Erupting volcanoes are very difficult to predict. The most important thing is to keep your distance. The changing landscape can act as a guide. It is important to never step on the blue flames. The blue flames, while beautiful, are the result of sulfuric gas exposure. The flames are blue due to sulfur-rich gas. The danger of the blue flames of Kawa Ijen is a slight breeze. The force of the wind determines how far the gas travels.
