Several villages in Bali were covered in a thin layer of ash but no smoke or lava was detected coming from the crater and no evacuation has been ordered.
Ngurah Rai International Airport spokesman Arie Ahsanurrohim said that flights were operating normally. Authorities said the air around Denpasar, the Bali provincial capital, is clear from ash.
In June, dozens of flights were cancelled after Agung erupted and shot a fresh plume of smoke and ash more than 1000 metres into the sky.
Agung’s last major eruption in 1963 killed around 1600 people.
