Nearly 35,000 people have been evacuated from their homes near an active volcano in Bali, as authorities warn it could erupt imminently.
The area around Mount Agung has seen hundreds of tremors and signs of magma rising to the surface in recent days.
Authorities have imposed a 12km (7.5 miles) exclusion zone around the mountain and issued their highest level alert on Friday.
The island's main tourist areas and flights remain unaffected for now.
Indonesia's national volcanology centre said in a statement (in Indonesian) on Sunday night that the mountain's "seismic energy is increasing and has the potential to erupt".
Officials said they started detecting shallow tremors in late August, and first raised the alert from "normal" to the second-tier "vigilant" level on 14 September. Indonesia has a four-level volcano alert system.
Within days the volcano showed increasing signs of activity, and authorities stepped up their alerts and evacuations of the rural villages surrounding the mountain. The area is now under the highest "danger" level.
Thousands of Balinese are now living in shelters in town halls and schools, with authorities trucking in tonnes of aid supplies. Some communities have also set up livestock shelters for the cows which they had to leave behind, reported The Jakarta Post.
Many villagers are still visiting their homes in the daytime and life is continuing normally, according to Reuters news agency.
Mount Agung, which is more than 3,000 metres above sea level, lies in the eastern part of Bali, which is a popular tourist destination.
The volcano is about 70km from the main tourist areas of Kuta and Seminyak, which remain unaffected for now.
Flights in and out of Bali are operating normally. The local tourism board said on Sunday that boats connecting to neighbouring islands Lombok and Java, also popular with holidaymakers, were on schedule.
The board added that though there was no volcanic ash detected, visitors were still advised to "start preparing sufficient stock of face masks" in case of an eruption.
Several countries including Britain, Australia, and Singapore have issued travel advisories for their citizens, warning of possible flight disruptions and evacuations.
More than 1,000 people died when Mount Agung last erupted in 1963.
Mount Agung is among about 130 active volcanoes in Indonesia - an archipelago prone to volcanic eruptions and earthquakes as it sits on the Pacific "Ring of Fire".
