Can you swim in Kawah Ijen?
High in the rugged mountains of Indonesia’s Ijen volcano complex lies a beautiful, turquoise-colored lake, but taking a dip in its waters would be deadly.
How old is IJEN?
Volcanic History. About 300,000 years ago, volcanic activity in this area began building a large stratovolcano that is called “Old Ijen” today. Over thousands of years and repeated eruptions, it grew to an elevation of about 10,000 feet.
Why does Kawah Ijen have blue lava?
The effect is caused by the fact that the lava emerges alongside super-hot, high-pressure sulfuric gases. The gases ignite when sparked by the red-hot lava and mixed with oxygen, resulting in brilliant blue flames that can reach as high as 16 feet (5 meters) into the air.
Where is Kawah Ijen volcano?
Indonesia
Kawah Ijen is a composite volcano located at the easternmost part of Java island in Indonesia and hosts the largest natural acidic lake in the world. We have gathered all available historical reports on Kawah Ijen’s activity since 1770 with the purpose of reviewing the temporal evolution of its activity.
Can a volcano turn a lake to acid?
Yes. Crater lakes atop volcanoes are typically the most acid, with pH values as low as 0.1 (very strong acid). Normal lake waters, in contrast, have relatively neutral pH values near 7.0.
What is the most acidic lake in the world?
The turquoise lake in the crater of the Kawah Ijen volcano looks serene and inviting. It also happens to be the world’s largest acidic lake. The water in the crater lake has a pH less than 0.3 on a scale of 0 to 14 (7 is neutral).
Is Ijen active?
Mount Ijen in East Java, Indonesia, is an active volcano that contains an acidic lake and a sulfur mine. Deep in the crater, in air heavy with toxic gases, miners extract chunks of sulfur.
How is blue lava made?
“Blue lava” is an electric-blue fire that burns when sulfur combusts, producing a neon-blue flame. Sulfur burns when it comes into contact with hot air at temperatures above 360 °C (680 °F), which produces the energetic flames. Actual lava is red-orange in color, given its temperature.
Is there purple lava?
The volcano contains large amounts of pure sulfur, which emits an icy violet color as it burns, filling the air with toxic fumes. The picture above was taken in a low lying field in Ethiopia. So what we’re seeing here is not actually blue lava, but normal, bright purple lava, surrounded by blue flames.
What is special about Kawah Ijen?
Kawah Ijen Crater Lake, at the top of the volcano, is the world’s largest such body of water filled with hydrochloric acid. In fact, it’s the acid that makes the water green.
Is blue fire real?
Can you swim in a volcano?
If jumping off a cliff into clear blue water isn’t enough of an adrenaline-pumping adventure, you can now do it in the middle of a volcano in Samoa. To-Sua Ocean Trench — “To-Sua” translated means “giant swimming hole” —is a 98-foot deep natural pool located on the southeast coast of Upolu Island.
Is blue lava hotter than regular lava?
In other words, it is glowing red hot, which occurs at temperatures in the 1150°–600°C range. At much higher temperatures, around 6000°C and up, black-body emission is distinctly blue, but this is much, much hotter than any magma can achieve naturally on Earth.
Do people live near Kawah Ijen?
About 12,000 people live in the caldera. The active crater at Kawah Ijen has a radius of about 1,100 feet (360 m). The acidic crater lake is about 600 feet (200 m) deep. Sulfur gas is condensed in the crater and mined.

Is there green lava?
The color of lava depends on the temperature of the flow as well as the chemical composition and any impurities that are in the liquid rock. Colors can include black, red, gray, brown and tan, metallic sliver, pink, and green.
Is blue lava real?
Does lava feel wet?
Brooke – So, in the strict definition of things, lava can’t be wet because it’s not a liquid, it can’t make things wet or saturate them. If you watch a video of something getting thrown into lava, it doesn’t go “splash” and sink, it goes “thud” and then bursts into flames.
