The Mount Agung volcano on Bali is spewing a thick plume of grey smoke two kilometres into the atmosphere, the country's disaster management agency says.
The volcano's alert remains at the highest level but the island's international airport was operating normally, agency spokesman Sutopo Nugroho said on Friday.
Authorities raised the warning alert to the highest level on November 27 and ordered the evacuation of nearly 100,000 people.
The 3,031-metre Mount Agung last erupted for a period of almost a year in 1963 and 1964, killing about 1200 people.
Indonesia sits on the so-called Pacific Ring of Fire, an area known for seismic upheavals and volcanic eruptions.
