A column of steam vapour is now visible above Bali's Mount Agung volcano.
The venting means the mountain is heating up — it hasn't erupted yet, but it might at any time, and the uncertainty is affecting tourism in some parts of the island.
In Bali's north-east, the town of Amed is normally bustling with tourists on diving holidays — today, it's empty.
"I'm not happy," 13-year-old Ni Made Febriana said.
"It's not fun, there are no tourists … they are afraid of earthquakes, and they have evacuated to some places with their friends."
Amed is about four kilometres outside the Mt Agung exclusion zone, but even if you couldn't see the massive volcano rising above the town, the regular tremors are a reminder of the proximity of the volcano — the mountain is being rocked by up to 1,000 tremors a day.
Further down Amed beach, closer to the three-kilometre high Mount Agung, cafe owner I Nyoman Kari lamented the lack of business.
"In Amed, all tourists have gone home because they are afraid of the eruption, two weeks ago, all tourist started to go home," he said
"Businesses like the speedboats have been evacuated to a safer place … the speedboats are very expensive, so we wanted to move it away from the ash.
"Besides, there are no guests here who want to cross to Gili [islands], that's the problem."
Restaurant worker Komang Putra said he had gone two days without serving a customer.
"Before the news about Mount Agung, we'd maybe have six tables during the day and it would get more crowded at night, around eight tables," he said. "But for the past six or seven days, it has been quiet."
Some neighbouring businesses have already closed.
"Maybe [this weekend] I will talk to the boss, to see how's the situation, should we close it down or keep it going," Mr Putra said.
Indonesia's National Disaster Management Agency spokesman Sutopo Purwo Nugroho said around 135,000 people are now registered with evacuation centres.
Some of them lived outside the exclusion zone but were uncertain about the safety of their homes.
"The danger line on the map is not clearly visible on the field, hence many people are afraid," he said.
"Also the number of hoaxes on social media [about an eruption] adds to the level of fear felt by many people including people who live in safe zone."
'I don't know where my kids will sleep'
About 104,000 people are taking refuge in makeshift shelters in Bali, with the volcano's alert status raised to the highest level last week.
Evacuees are huddling in tents, school gyms and government buildings.
Farmer Gusti Gege Astana told Reuters he was worried lava would destroy his home.
"I don't know where my kids will sleep and all I can do now is pray," he said.
Mount Agung last erupted in 1963, killing 1,000 people. There are more than 100 volcanoes in Indonesia and once they start to show high levels of activity, it can take weeks and even months for them to erupt.
Flights are operating as normal and Bali's tourism department issued a letter this week to reassure tourists.
"The island is safe except for areas around Mount Agung. We urge tourists to continue visiting," it said.
