Bali‘s highest volcano Mount Agung threatens the lives of thousands of locals as powerful rivers of debris flow down the active volcano slopes.
Shocking footage from iNews shows a lahar – a type of mudflow containing volcanic debris and water – powerfully flowing through Kali Unda Dam in the Klungkung area of Bali.
The cement-like mixture of water and ash flows down at rapid speed as people watch on from the riverbank despite warning from the Indonesian Government to stay away from the water.
The Kali Unda Dam is a popular spot with the locals who use the river waters to bather and wash their clothes.
A spokesman for Indonesia’s Disaster Mitigation Agency (BNPB) warned against going close to rivers near Mount Agung.

Sutopo Purwo Nugroho warned said on Twitter: “Watch out for lahar floods (cold lava) around Mt Agung.
“Lahar floods have already occurred in several places on the slopes.”
Lahars were seen flowing down the Yeh Sah River in Karangasem, according to Coconuts Bali and farmlands in the area had already reportedly been damaged by the mud.
Mr Nugroho added that some locals who live close to Bali’s Mount Agung have so far refused to evacuate the area despite repeated warnings.
He continued: “Some people within a radius of 8-10km from the summit crater of Mount Agung have been displaced.
“They feel safe because the area was not damaged during the 1963 eruption. They will evacuate if it’s dangerous.”
Mount Agung‘s last eruption in the 1960s caused the death of an estimated 1600 people and the destruction of many villages on one of the most devastating eruptions in Indonesia’s history.
Bali airport has been closed and several major airlines have announced they have cancelled flights due to the risks to the air engines caused by the ash cloud released by Mount Agung.
