History of Mount Ijen
Based on historical records, Mount Ijen Caldera Genesa was first created by Van Bammelen in 1941. Then refined by several subsequent writers. Conditions in the Pre-caldera (before the caldera formed), it is not known what happened before 300,000 years ago, but it is estimated that a single Stratovolcano (Paleo Ijen) with an estimated altitude of 3500 m has formed. The mountain, which contains lava and pyroclastics, is located on Miocene (12.5 million-year-old) sediment in the form of limestone.
The formation of the caldera is thought to be associated with a large-volume eruption that produced (~80 km3) pyroclastic-flow deposits, which reached a thickness of 100-150 m. The most extensive is on the northern slopes of this volcanic complex. This event is thought to have occurred sometime before 50,000 years ago. This is concluded based on age analysis of the K-Ar (50 ± 20 ka) of the lava flows from Mount Blau which is considered to be the oldest post-caldera unit. At that time it is also estimated that a lake will form on the caldera floor. A sedimentary lake consisting of shale, sand, and river channels exposed sediments in the northern area near Blawan.
Volcanic activities after the formation of the caldera include phreatomagmatic, phreatic, strombolian, and Plinian eruption phases which produce circular cones, which are generally composite buildings, and inner cones, most of which are built by volcanic ash material. The volcano produced young volcanic ash and cones of scoria (pumice), as well as lava, pyroclastic flow deposits, and deposits of avalanche material and debris that now includes the caldera flow. According to Sitorus (1990) radiocarbon dating of pyroclastic-flow deposits yielded ages > 45,000 BP (in Jampit) 37,900 ± 1850 (in Suket), 29,800 ± 700 (in Ringgih), 24,400 ± 460 (in Pawenen Tua), 21,100 ± 310 (in Malang) and 2,590 ± 60 (in Ijen).
