mining at Ijen. This image shows the dangerous and rugged conditions the miners face, including toxic smoke and high drops, as well as their lack of protective equipment. The pipes over which they are standing serve to guide sulfur vapors and condense them, thereby facilitating production. The Ijen volcano complex is a group of composite volcanoes located on the border between Banyuwangi Regency and Bondowoso Regency of East Java, Indonesia. It is known for its blue fire, acidic crater lake, and labour-intensive sulfur mining. It is inside an eponymous larger caldera Ijen, which is about wide. The Gunung Merapi stratovolcano is the highest point of that complex. The name "Gunung Merapi" means 'mountain of fire' in the Indonesian language; Mount Merapi in central Java and Marapi in Sumatra have the same etymology. Ijen Geopark stretches across the entire regency which is specifically in the Mount Ijen area, Pulau Merah Beach, and Alas Purwo National Park. It has various geological, biological, and cultural sites. It became part of UNESCO Global Geoparks in 2023. West of Gunung Merapi is the Ijen volcano, which has a turquoise-coloured acidic 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.…

It is known for its blue fire, acidic crater lake, and labour-intensive sulfur mining. It is inside an eponymous larger caldera Ijen, which is about wide. The Gunung Merapi stratovolcano is the highest point of that complex. The name "Gunung Merapi" means 'mountain of fire' in the Indonesian language; Mount Merapi in central Java and Marapi in Sumatra have the same etymology. Ijen Geopark stretches across the entire regency which is specifically in the Mount Ijen area, Pulau Merah Beach, and Alas Purwo National Park. It has various geological, biological, and cultural sites. It became part of UNESCO Global Geoparks in 2023. West of Gunung Merapi is the Ijen volcano, which has a turquoise-coloured acidic 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 US$13 per day and, once out of the 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 runs east–west across the southern side of the caldera. The active crater at Kawah Ijen has a diameter of and a surface area of . It is deep and has a volume of . The lake is recognised as the largest highly acidic crater lake in the world. It is also a source for the river Banyupahit, resulting in highly acidic and metal-enriched river water which has a significant detrimental effect on the downstream river ecosystem. During a scientific expedition in 2001, the pH of the lake was measured at File:Blue flames in the Ijen Caldera.jpg|Blue flames caused by the burning of sulfur in the Ijen caldera File:Kawah Ijen volcano, Java.jpg|Kawah Ijen volcano and crater lake, Java, viewed from Landsat 8 File:The cauldron of Ijen Mountain, Indonesia.jpg|The sulfuric lake of Kawah Ijen Mountain's cauldron, Indonesia File:Mount Merapi Ijen A.JPG|Mt.
