Ijen caldera is the largest in Java with a diameter of 16 km. The size of the crater is about 960 m x 600 m.
Several extinct active cones are found inside the caldera such as G. Cilik (1872 m), G. Pendil (2375 m), G. Anyar (1276 m), G. Genteng (1712 m), G. Gelaman (1726 m), G. Kukusan (1994 m), G. Papak (2099 m), G. Widodaren (2100 m), G. Blau (1774 m), G. Gendingwaluh (1519 m), G. Lingker (1630 m), G. Kunci (1788 m).
The primary dangers at Ijen are pyroclastic flows, lahars, and lava flows.
Thermal springs are located on Ijen lakeshore. The lakeshore fumarole discharges (T=170~245°C) have both a magmatic and a hydrothermal component.
Miners dig sulphur from the active vents at Ijen.
Liquid
red sulphur erupts from the vents and cools to a yellow colour. - John Seach
