Description

Ijen Crater is one of tourism object in East Java, very  popular with most beautifull crater lake in the world and also SUNRISE  tour.

The Ijen volcano complex is a group of stratovolcanoes in the  Banyuwangi Regency of East Java, Indonesia. It is inside a larger  caldera Ijen, which is about 20 kilometers wide. The Gunung Merapi  stratovolcano is the highest point of that complex. The name “Merapi”  means “mountain of fire” in the Indonesian language; 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-kilometer-wide turquoise-colored acid crater lake. The lake is the  site of a labor-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 90,000 – 130,000 ($8-$10) per day and  once out of the crater, still need to carry their loads of sulfur chunks  about three kilometers to the nearby Pultuding 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  crater at Kawah Ijen has a diameter of 722 metres (2,369 ft) and a  surface area of 0.41 square kilometres (0.16 sq mi). It is 200 metres  (660 ft) deep and has a volume of 36 cubic hectometres (29,000 acre·ft).

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. In 2008, explorer  George Kourounis took a small rubber boat out onto the acid lake to  measure its acidity. The pH of the water in the crater was measured to  be 0.5 due to sulfuric acid.
