TWO Australian tourists are in trouble with Bali police after mistakenly climbing the region’s bellowing Mount Agung volcano.

Police were waiting for Ricky Tonacia, 34, and Jack Dennard, 26, when they returned from their climb up the volcano, the ABC reports.

Police said the men began their climb at 2am and descended eight hours later.

“We went to the gate at border of the no-climbing danger zone, and we met two guides who were waiting for them to come back down from the top,” reported the police chief from the town of Selat, Sudartawan.

“The local military chief and I and some volunteers waited for them to come back and when they came back we secured them afterwards at Selat Police Office, to get their statements.”

According to police the men began their climb at 2am and told authorities they were not aware of the 8-10 kilometre exclusion zone set up as a safety guard around the edge of the volcano as it continues to erupt and spew gases and ash into the air.

News.com.au have contacted the men for a statement.

The exclusion zone is widely publicised throughout the island and beyond. National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho tweeted “the status remains the same CAUTION”.

The men were let go and allowed to return to their accommodation in the coastal village of Canggu.

Last week, a Balinese priest dubbed the “gatekeeper” of an erupting volcano delivered an astounding prediction using “vision of the inner eye” over the fate of its next explosion.

Spiritual leader Mangku Bon made headlines in October when he trekked to the very top of Bali’s Mount Agung volcano amid increasingly frequent tremors and earthquakes from the “pulsating” beast.

The priest predicted Mount Agung would erupt for another nine months, yet urged “it will not be a big explosion. It will continue to be a slow eruption”.

The next eruption though, may be a different story.

“The next explosion will be in 45 years (2062). The next explosion will be big like 1963.”
