Revealing the History of the Formation of Ijen Crater
History of the Formation of Ijen Crater, Ijen Crater is one of the most famous natural attractions in Indonesia, especially in East Java. Located on the border of Banyuwangi and Bondowoso Regencies, this crater is famous for its stunning views, especially at night when blue flames erupt from inside the crater. In addition, Ijen Crater is known to contain the largest acid lake in the world.
The Geological Origin of Ijen Crater
Ijen Crater is a volcanic crater formed due to very long volcanic activity. Mount Ijen itself is a volcano in an area with a very interesting geological history. In general, a crater is a large basin formed by a volcanic eruption or the collapse of a volcano‘s top after a major eruption. Mount Ijen is estimated to have formed around 30–35 million years ago as a result of tectonic processes in Southeast Asia. At first, this area was part of Mount Ijen Purba which existed since 300 thousand years ago. About 70 thousand years ago, there was a violent eruption that resulted in the formation of a large caldera that we know today as Ijen Crater.
Characteristics of Ijen Crater
Ijen Crater has several unique characteristics that make it an attractive tourist attraction. One of the striking withering features is its tosca green crater lake, which is the world‘s largest acidic lake with a very high level of acidity. The blue flame phenomenon is also the main attraction of Ijen Crater. This blue flame appears as a result of a reaction between hydrogen sulfide (H2S) gas and oxygen at high temperatures on the crater surface. The blue flames are only visible at night until late morning, making it a highly sought–after experience for hikers and tourists alike.
The Enchanting Blue Flame Phenomenon
One of the interesting withering natural phenomena in Ijen Crater is its blue flames. This blue flame was first discovered by sulfur miners working around the crater. They use sulfur gas to burn sulfur which is then utilized in various industries. This blue flame was formed by burning sulfur gas that came out of cracks in the crater walls. The sulfur gas that comes out then mixes with oxygen in the air and burns at very high temperatures, resulting in a blue flame. The blue light that burns in the middle of the night creates a very spectacular and mesmerizing scene. One of the interesting withering natural phenomena in Ijen Crater is its blue flames.

History of the Formation of Ijen Crater
The origin of Ijen Crater cannot be separated from volcanic activity that has occurred in the East Java region since millions of years ago. Geological processes involving the movement of tectonic plates, volcanic eruptions, and the accumulation of gases and minerals from within the earth, produce this crater with stunning views. The blue fire phenomenon born from burning sulfur dioxide gas, as well as the acid lake which is one of the largest in the world, further adds to the attraction of Ijen Crater as an extraordinary natural tourist attraction.
