What is Ijen?
Ijen is it Mount Ijen volcano complex is a group of composite volcanoes in the Banyuwangi Regency part of East Java province, Indonesia.
Inside a larger caldera Ijen, which is about 15 kilometres wide. The Gunung Merapi stratovolcano is the highest point of that complex. The name “Gunung Merapi” means “mountain of fire” in the Indonesian language (api being “fire”); Mount Merapi in central Java and Marapi in Sumatra have the same etymology.
West of Gunung Merapi is the Ijen volcano, which has a one-kilometre-wide turquoise-coloured acidic ijen crater lake. The lake is the site of a labour-intensive sulfur mining operation, in which sulfur-laden baskets are carried by hand from the crater floor. The work is paid well considering the cost of living in the area, but is very onerous.Workers earn around Rp 40,000 – 80,000 ($4-$8) per day and once out of the ijen crater, still need to carry their loads of sulfur chunks about three kilometers to the nearby Paltuding Valley to get paid.
Many other post-caldera cones and craters are located within the caldera or along its rim. The largest concentration of post-caldera cones run east-west across the southern side of the caldera. The active ijen crater at Kawah Ijen has a diameter of 800 metres and a surface area of 0,5 square kilometres. Is it 200 metres deep and has a volume of 40 cubic hectometers.
Lake of ijen crater is recognised as the largest highly acidic ijen crater lake in the world. It is also a source for the river Banyupahit (water bitter), resulting in highly acidic and metal enriched river water which has a significant detrimental effect on the downstream river ecosystem.
