Kawah Ijen Lake in Indonesia is known as the largest acid lake in the world. At night, the lake glows with a mysterious blue light, concealing deadly secrets…
Ijen (Kawah Ijen) is located 26km northwest of Banyuwangi town, and is one of 76 active volcanoes in Indonesia.
The Ijen crater has a recorded radius of 361m, a surface area of 410,000m2, a depth of 200m, and a volume of 36 million m3.
Kawah Ijen Lake, or the Kawah Ijen crater, has a stunning turquoise color.
The turquoise color of Kawah Ijen Lake is due to high concentrations of acid and dissolved metals. These originate from the large amounts of magma deep beneath the lake.
The activity of the magma chamber continuously releases toxic sulfur gases, enveloping the surface of Kawah Ijen Lake in a white haze year-round.
At night, the landscape transforms completely, exuding an eerie charm.
