DENPASAR, Indonesia, Nov 13, (AP): Several international airlines canceled flights to and from Indonesia’s tourist island of Bali on Wednesday as an ongoing volcanic eruption left travelers stranded at airports. Indonesia’s Mount Lewotobi Laki Laki volcano on the remote island of Flores in East Nusa Tenggara province spewed towering columns of hot ash high into the air since its initial huge eruption on Nov 4, killed nine people and injured dozens of others.

The 1,584-meter (5,197-foot) volcano shot up ash at least 17 times on Tuesday, with the largest column recorded at 9 kilometers (5½ miles) high, the Center for Volcanology and Geological Disaster Mitigation said in a statement. Authorities on Tuesday expanded the danger zone as the volcano erupted again to 9 kilometers (5½ miles) as volcanic materials, including smoldering rocks, lava, and hot, thumb-size fragments of gravel and ash, were thrown up to 8 kilometers (5 miles) from the crater on Friday.

The activity at the volcano has disturbed flights at Bali’s I Gusti Ngurah Rai international airport since the eruption started, airport general manager Ahmad Syaugi Shahab said. Over the past three days, 46 flights, including 30 scheduled to depart and 16 due to arrive, were affected. Shahab said that at least 12 domestic flights and 22 overseas one were canceled on Tuesday alone.

For these cancellations, the airlines were offering travelers a refund, or to reschedule or reroute, he said. Three Australian airlines have also canceled or delayed a number of flights. Jetstar has paused its flights to Bali until at least Thursday, it said on its website, saying it was "currently not safe” to operate the route. Virgin Australia’s website showed 10 services to and from Bali were canceled on Wednesday. Qantas said it has delayed three flights.

Some airlines are offering fare refunds for upcoming Bali flights to passengers who don't want to travel. Air New Zealand canceled a flight to Denpasar scheduled for Wednesday and a return service to Auckland due to depart Bali on Thursday. Passengers would be rebooked and the airline would continue to monitor the movement of ash in the coming days, Chief Operating Officer Alex Marren said.
