1979 eruption of Sinila crater

Over 175 people died, mainly due to gas poisoning in villages on the plateau near the Sinila crater.

[10] The eruption involved explosions, the expulsion of rocks and mud, intense steam and gas release, and a hot lahar that flowed over roads and farmland along a 3.5 km stretch.

Voluminous amounts of carbon dioxide started to emerge from both the fracture and the Sigluduk crater, and sheets of the dense gas flowed down to the Batur plain.

[4] As the eruption took place during the night, people inhaled the poisonous gases during their sleep and died.

[13] The rescue work was made difficult due to toxic gases and difficulty accessing the area.

The vegetation around which had already suffered damage from the eruption also showed signs of chemical destruction where the gas flowed.

[16] The Indonesian government ordered that an area of 3 kilometres (1.9 mi) around the mountain be evacuated, affecting around 17,000 people.

Evacuation efforts were hampered due to lava severing main roads, restricting access to the area.

Most recent report indicated that 2023, the carbon dioxide emissions have decreased and the alert level for the Dieng Volcanic Complex has been lowered to 1 (on a scale of 1-4).
