The National Disaster Management Agency (BNBP, Indonesia) maintains level of Eruption Alert 3 ( maximum is 4) and reported Ash rain in at least 7 populations on island. More eruptions followed and continued into Sunday, with a "medium-pressure eruption" in the early evening that sent ash 2,000 meters into the air, the agency said.
Even if visibility is clear, volcanic ash can damage an airplane's engine.
Airlines have issued a shock "red warning" about the impending danger of volcanic ash in the skies over Bali, following the second emission from Mount Agung this week.
People living within 7.5 kilometers of the mountain have been told to evacuate, senior volcanologist Gede Suantika said, advising residents to remain calm.
Bali is an important tourist centre and the worldwide airport of Denpasar, the capital of the island, is operating normally for the moment, even if some airlines chose to cancel their flights.
Bali is a popular tourist destination, known for its seaside resorts and sandy beaches.
Most recently, the 3,142-metre volcano spewed grey smoke and ash as high as 700 metres Tuesday, and again Saturday to twice that height, before beginning to emit lava Sunday.
Under these circumstances, Garuda Indonesia enforces exemption policy for cancellation fee, rebooking/reroute fee, refund fee, administration fee and other ticket change fees for passengers who have scheduled flights to and from Lombok.
There are fears the volcano could erupt for the first time since 1963, when almost 1,600 people died.
As of 6.20am Sunday local time, smoke and ash billowed 4km above Mount Agung.
At present, more than 25,000 people in Karangasem district continue to be displaced by eruption alert, although number reached 140,000 at end of September.
On Oct 29, the centre lowered the volcano's alert level by one notch after it was raised to 4 on Sept 22 in response to the most intense volcanic activity recorded in 53 years.
