Several airlines have canceled flights between Australia and Bali due to dangerous ash clouds from a volcano near the Indonesian resort island.

Qantas, Jetstar and Virgin Australia informed passengers of the disruptions on Wednesday, saying ash from Mount Lewotaobi Laki-laki made it unsafe to fly.

The volcano spewed a 9-kilometer (6.2-mile) plume of ash into the sky over the weekend, a week after a large eruption killed 10 people.

Australia’s Bureau of Meteorology also warned that volcanic ash could move into northern parts of the country on Wednesday.

Jetstar said all flights to and from Bali until 12:00 Australian Eastern Time on Thursday (04:00 GMT) have been cancelled. Virgin Australia canceled all its flights to and from Bali on Wednesday.

Jetstar also said it would soon mount additional flights between Bali and Australia using its larger Boeing 787 aircraft to carry more passengers.

Activities in Indonesia have also been affected by volcanic ash.

A jazz festival in the city of Labuan Bajo, about 600 kilometers from Mount Lewotaobi Laki-laki, has been postponed until next year for security reasons.

Indonesia lies on the Pacific “Ring of Fire,” an area of ​​high seismic activity atop multiple tectonic plates, and has about 130 active volcanoes.

Past volcanic eruptions have disrupted aviation. In 2020, Ash clouds from Mount Merapi close an airport in the city of Solo.
