Airlines in Australia, Hong Kong, India, Malaysia and Singapore cancelled flights to and from the Indonesian resort island of Bali on Wednesday, after a nearby volcano catapulted an ash tower miles into the sky.
Australia’s Jetstar, Qantas and Virgin Australia all grounded flights after Mount Lewotobi Laki-Laki on Flores island spewed a 9km (5.6-mile) tower of ash a day earlier.
Malaysia Airlines, AirAsia, India’s IndiGo and Singapore’s Scoot also listed flights as cancelled on Wednesday, according to a journalist at Bali’s international airport.
“Volcanic ash poses a significant threat to safe operations of the aircraft in the vicinity of volcanic clouds,” said AirAsia as it announced several cancellations.
Multiple eruptions from the 1,703-metre (5,587-foot) twin-peaked volcano in recent weeks have killed nine people, with 31 injured and more than 11,000 evacuated, Indonesia’s disaster mitigation agency said on Tuesday.
Eruptions can pose serious risks to flights, disgorging fine ash that can damage jet engines and scour a plane’s windscreen to the point of invisibility.
