Snakes and monkeys have reportedly begun fleeing the area around Mount Agung in their droves, in what locals claim is the strongest sign yet the Bali volcano will erupt.
Located on the east of Indonesia's main island, the volcano - which last erupted back in 1964 - has experienced a major increase in the rate of tremors over recent days.
Fearing an eruption is imminent, the nation's authority raised the alert level up to the highest rating, leaving the holiday hotspot bracing for travel chaos should it explode.
But while tourists continue to flock to the Indonesian capital, thousands of animals in the area have fled down the mountain and into nearby villages - one of the top signs a volcano is set to erupt.

Snakes and monkeys have reportedly begun fleeing the area around Mount Agung (pictured), in Bali, in their droves in what locals say is a sign the volcano is set to erupt
If Mount Agung (pictured) in Bali erupts it could cause chaos for thousands of Australians who have travelled there for the school holiday season
Sogra Village elder and Balinese priest Wayan Sukra told local media Bali Tribun that the animals had been on the move for three days.
'Maybe because it's hot on Mt. Agung. So the animals are exiting and coming to settled areas,' he said.
'Maybe this is a sign that the mountain will erupt (because) this condition is not usual.'
Mr Sukra said a similar phenomenon took place during the 1963 eruption.
Up to 30,000 villagers in the area around Mt Agung have left their homes after two fires broke out this week and smoke was seen rising from the summit.
The Department of Foreign Affairs and Trade (DFAT) has updated a travel warning for Australians heading to Bali, telling them to make contingency plans for an eruption.
