|Dieng Plateau is an active volcanic area in Central Java, which belongs to Banjarnegara and Wonosobo regencies. Located in the west of the complex of Mount Sindoro and Mount Sumbing.
The name Dieng comes from a combination of two Kawi words: “di” meaning “place” or “mountain” and “Hyang” meaningful (Gods). Thus, Dieng means mountainous area where the gods and goddesses reside. Another theory states, the name Dieng derived from the Sundanese language (“in hyang”) as it was estimated in the pre-Medang era (around the 7th century AD) the area was in the political influence of Galuh Kingdom.
The active crater at Dieng is a crater for volcanic activity under the highlands. Activity monitoring was conducted by PVMBG through Dieng Observation Post in Karangtengah Subdistrict. Here are the monitored active craters:
- Sikendang, potentially poisonous gas
- Sinila, potentially poisonous gas
- Timbang, potentially poisonous gas
