Why Kawah Ijen Indonesia have blue lava at night?

But at Kawah Ijen, extremely high quantities of sulfuric gases emerge at high pressures and temperatures (sometimes in excess of 600°C) along with the lava. Exposed to the oxygen present in air and sparked by lava, the sulfur burns readily, and its flames are bright blue.

What is special about the Kawah Ijen volcano?

Why do they mine sulphur in Indonesia?

Several hundred men work in the heart of Ijen volcano in East Java, Indonesia. Each day, they collect yellow lumps of sulphur that solidify beside its acidic crater lake.

In the past 50,000 years, many small stratovolcanoes have formed within Old Ijen’s caldera and covered its southern and eastern margins. Kawah Ijen covers part of the eastern margin. Thousands of years of weathering have converted the pyroclastic deposits into rich, fertile soils which now support coffee plantations.
