The Indonesian Kawah Ijen Crater Lake exhibits a deceptive allure with its vivid yet poisonous waters, holding the title of the largest acidic lake on the planet. This lake is distinguished by its luminous blue hue and the surreal blue flames that emerge at night due to the combustion of sulfuric gases, all under the shadow of the majestic Raung Volcano.
Is there anything more haunting than the ‘greatest acid basin on the planet’? Situated in East Java, Indonesia, the Kawah Ijen Crater Lake presents a hauntingly beautiful vision, especially apt for the eeriness of Halloween.
Observing Kawah Ijen from the Cosmos
The visuals provided have been sourced from the Copernicus Sentinel-2 mission, which supplies detailed optical imagery of the terrestrial landscape. The true-color representation reveals Kawah Ijen’s stunningly vivid turquoise waters.
The waters may appear welcoming, but they are saturated with an intense blend of sulfuric and hydrochloric acids, coupled with dissolved minerals, rendering it a no-go zone for swimmers. Yet, this chemical composition allows the lake to be distinctly visible from space. The pH levels in Kawah Ijen Crater Lake can plummet to 0.5, indicative of an acidity comparable to that of automotive battery acid.
A Fusion of Terror and Natural Marvel
Conversely, the image further down is tailored to evoke a sense of terror fitting for Halloween. It is a product of particular spectral band usage from Sentinel-2, typically employed for observing coastal and oceanic water color. This specialized band mix renders the lake highly reflective, accentuating its electric blue coloration against its surroundings.

Beyond the lake’s extraordinary acidity, it is also notorious for releasing heated, combustible sulfuric gases that spontaneously ignite upon contact with the oxygen-rich air of our atmosphere. This results in the uncanny, blue flames that provide an almost mystical display at night.
Also featured in the images is the Raung or Gunung Raung Volcano, a notably active volcano on the island of Java, which rises to an altitude of 3332 meters (10,932 feet), dominantly situated to the immediate southwest.

Frequently Asked Questions (FAQs) about Kawah Ijen Crater Lake
What is the Kawah Ijen Crater Lake known for?
The Kawah Ijen Crater Lake is renowned for being the largest acidic lake in the world, with a striking turquoise color. It’s also famous for its surreal blue flames at night, caused by ignited sulfurous gases, all set against the backdrop of the towering Raung Volcano in East Java, Indonesia.
How are the blue flames of Kawah Ijen produced?
The blue flames of Kawah Ijen are produced when sulfurous gases, which emanate from the lake, come into contact with the oxygen-rich atmosphere and ignite. This creates a unique and eerie blue glow that can be seen at night.
Can you swim in Kawah Ijen Crater Lake?
No, swimming in Kawah Ijen Crater Lake is not possible due to the extremely high concentration of sulfuric and hydrochloric acids, along with dissolved minerals. The water’s acidity, with pH values as low as 0.5, makes it dangerously corrosive.
How visible is Kawah Ijen from space?
Kawah Ijen’s distinctively bright turquoise waters are highly visible from space due to the high concentration of acidic minerals and chemicals within the lake. This vivid coloration makes it easily distinguishable when observing Earth’s surface via satellite imagery.
What kind of satellite imagery is used to capture Kawah Ijen?
The Copernicus Sentinel-2 mission provides the satellite imagery used to capture Kawah Ijen. This mission utilizes optical imaging to document Earth’s surface, employing specific spectral bands that enhance the observation of coastal waters and ocean color, making features like Kawah Ijen stand out.
