Ijen crater blue fire and the largest highly acidic lake in the world. Kawah Ijen (2386 m) is a composite volcano located within the Pleistocene Ijen Caldera, at the easternmost part of Java island, in Indonesia (Fig. 1). The visible superficial manifestations of the hydrothermal system of Kawah Ijen’s activity consist of the world’s largest hyperacidic lake on Earth
The blue fire is ignited sulphuric gas, which emerges from cracks at temperatures up to 600 degrees Celsius (1,112 degrees Fahrenheit). Those gases are directly originated from the magmatic chamber under the volcano. The flames can be up to 5 metres high; some of the gas condenses to liquid and is still ignited. It is the largest blue flame area in the world and one of the purest sulfur mine. Escaping volcanic gases are channelled through a network of ceramic pipes, resulting in condensation of molten sulfur. The sulphur, which is deep red in colour 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. Miners carry loads ranging from 75 kilograms to 90 kilograms, up 300 metres to the crater rim, with a gradient of 45 to 60 degrees and Most miners make this journey twice a day.
Blue fire Kawah Ijen | The best time to see a blue fire in the Ijen crater is 1 hour after sunset and 1 hour before sunrise because when the sky is dark, the blue color will appear more clearly.
This phenomenon is really caused by the combustion of sulfur, of which Ijen has a number of the best levels in the world. The sulfuric gases are released from cracks within the rock at air mass and temperatures sometimes far more than 1,112°.
The blue fire will be reduced in size around 5 a.m.m because the sun will come at 5 a.m., so don’t go too late. when the sun rises, the blue fire will be reduced and cannot be seen. April to November is the best month to see the blue fire phenomenon.
Where can I see the blue fire Kawah Ijen?
Why does Ijen a crater have a blue fire ?
the lava molten rock that emerges from the Earth at ultra-high temperatures isn’t colored significantly differently than the lava at other volcanoes, which all differ slightly based on their mineral composition but appear a bright red or orange color in their molten state.
But at Kawah Ijen, extremely high quantities of sulfuric gases emerge at high pressures and temperatures (sometimes more than 600°C) along with the lava.
When sulfur from within the volcano breaches the surface, it can reach temperatures up to 600°C( 1, 112°F), and therefore the sulfur immediately encounters lower temperatures and pressures at the surface, which causes the sulfur to right away ignite and erupt blue flames up to five meters ( 16 ft) into the air.
Things you need to bring to see Ijen crater blue fire
- Torches (both hand torches or headlamps. We opted for the headlamps to maintain our palms-free), although I took both, simply in case the battery might run out withinside the night
- Gloves (it’s miles bloodless up there, however, they even serve you nicely whilst you pass down the crater and ought to preserve directly to sharp rocks)
- Gas masks, that you want as safety in opposition to dense clouds of poisonous gases like sulphur dioxide. You can not live for a long term in one’s gases without a mask. It all relies upon the wind if you’ll stumble upon a number of the ones poisonous gases on the day of your climb.
- Warm jacket. Now, do no longer count on the provider of a “cell second-hand iciness garments store”
