Mount Agung erupted for the second time in a week on Saturday and is now producing the dangerous volcanic mudflows known as lahars.
Terrifying video footage shows a lahar scooping up huge amounts of debris as it ploughs down the side of the Bali volcano.
The latest map produced showed a 10km exclusion zone being put in place to protect residents from the dangerous lahars.
The map, shown on Sky News, shows how areas, coloured in red, could be the most impacted by the volcanic mudflows.

The lahars form in rivers and are comprised of rocks, vegetation and volcanic ash.
A powerful lahar has the potential to destroy any house, bridge or road in its path, creating a huge cause for concern in the region.
Bali’s National Agency for Disaster Management (BNPB) spokesman Sutopo Purwo Nugroho told locals and tourists to stay well away from the lahars, saying that they could worsen as the island enters its rainy season.
Professor Joachim Gottsmann, head of volcanology at Bristol University, has warned that the lahars seen around Mount Agung could affect those outside the volcano’s exclusion zone.
He told Express.co.uk: “Lahars can perhaps be best described as being similar to very wet concrete.
“They are devastating because they are fast moving and erosive due to their volcanic debris load – they can also travel very far. Examples in the Andes report a 400km run out the distance from the source.
“Hence populations along rivers which are usually fed from water from a volcano are at risk from lahars even if they are well outside an immediate exclusion zone.”Experts have warned the next Mount Agung eruption could be “even bigger” than the previous ones over the last few days.
Bali Disaster Management Agency has warned the Bali volcano could explode more violently in the coming days and weeks.
Sutopo Purwo Nugroho said: “There is a high possibility of an eruption that could be bigger than before.
“A few signs indicate that activity will continue and that yesterday there were a few explosive eruptions.”
