This is one of Indonesia’s natural beauty charm outstanding and have led many tourists from various countries. This is where you can see an amazing wide crater lake along the blue flame of sulfur at night. In addition to being a tourist destination hiking, Ijen Crater is also a traditional sulfur mining areas up and down the former arena eruption crater which is still active.
Mount Ijen itself in the area of the crater Travel and Tourism Ijen Park Reserve in the district and sub-district Liciiin Klobang Banyuwangi regency. The mountain is located 2,368 meters above sea level where the peak is a series of volcanoes in East Java such as Bromo, Semeru and Merapi. Ijen Crater is the largest sulfur mining areas in East Java are still using traditional means. Ijen has sublimat source of sulfur which seemed inexhaustible used for various industrial chemicals and purification of sugar.
Ijen crater is one of the world’s most acid with caldera wall as high as 300-500 meters wide crater reached 5466 hectares. The crater in the middle of the caldera is the largest on the island of Java with a size of 20 km. The size of the crater itself is around 960 meters x 600 meters. The crater is located at a depth of more than 300 meters below the caldera wall.
Views of the Ijen crater are so amazing when illuminated by the morning sun emits turquoise sheen. The by the camera. Water crater bluish green, quiet but you are not allowed to descend because water crater volume of approximately 200 million cubic meters heats at 200 degrees Celsius. The degree of acidity is very high crater close to zero so that it can dissolve the human body even clothes quickly.
Early morning at 01.00 am, when the sun had not refract incandescent reveals the beauty of this crater lake there is another miracle presented Ijen. Under the crater glow blue flame (blue fire) of liquid sulfur flowing endlessly to be dried by the wind then chopped into cubes and miners. Chunks of sulfur are then placed on two wooden baskets and shouldered down the mountain as far as 3 miles. Not a light load because the weight of the basket can carry up to 100 kg.
In the southeast crater there solfatara field which is the crater lake wall. In the western part of the crater there is a dam which is upstream of Kali Banyupait. Field solfatara Mount Ijen always, release of volcanic gases with a high concentration of sulfur gases and odors that sometimes sting. Dam Ijen is part of the attraction interesting, but not always visited by tourists because of the way to get there is quite difficult and often damaged by landslides. Ijen Crater Dam is a concrete building built since the time of the Netherlands and is intended to regulate the water level of the lake so as not to cause flooding acidic water. But the dam is now not working because the water never reached the door of water due to water seepage under the dam lake.
