DENPASAR, Indonesia: Bali’s international airport will be closed for a third day, Indonesian officials said on Wednesday, as ash from a rumbling volcano that looms over the island paradise poses a danger to planes. Mount Agung could produce a thunderous eruption at any moment, officials have warned, forcing the main airport to be shut since Monday. Massive columns of thick grey smoke and ash that have been belching from the volcano since last week have now begun shooting high into the sky, forcing hundreds of flights to be grounded and stranding around 120,000 tourists. Ash is dangerous for planes as it makes runways slippery and can be sucked into their engines. “Bali’s Ngurah Rai airport will remain closed until at least Thursday morning,” airport spokesman Arie Ahsanurrohim told Agence France-Presse.
