Bali Flights Resume After Volcanic Ash Disrupts Travel
A volcano’s eruption in Indonesia caused significant flight cancellations, stranding travelers and disrupting schedules. Ash spewed high into the sky, impacting airports and leading to closures as authorities assessed the dangers.
Volcanic Eruption’s Impact
Earlier this week, an eruption from Mount Lewotobi Laki Laki in Indonesia released a large ash cloud. The ash reached 11 kilometers into the atmosphere, creating a visible mushroom shape up to 150 kilometers away. The volcanology institute elevated the alert level to its highest.
On Wednesday, the eruption caused flight cancellations and delays. According to the airport operator, 87 flights to and from Bali were affected. This encompassed 66 international and 21 domestic flights. The ash and debris fell in areas outside the immediate danger zone.
Flight Resumption and Airport Reopenings
By Thursday morning, the ash cloud had dissipated, allowing flights from Bali to resume. Flights to destinations in Australia, Vietnam, Singapore, Malaysia, and China were operating on schedule. Airports in East Nusa Tenggara province also reopened on Thursday.
However, the Fransiskus Xaverius Seda airport in Maumere extended its closure until Friday. Officials expressed concern about volcanic ash in the air, which could pose a risk to aircraft.

“When ash enters a plane engine, the glass inside it melts, which then sticks to various other engine parts.”
— Statement from an aviation expert
According to the International Air Transport Association, volcanic ash can cause over $100 million in damages annually to the aviation industry (IATA, 2024).
Volcanic Risks for Aircraft
Volcanic ash poses a significant hazard to aircraft, as it can severely damage engines and affect flight controls. The ash can clog sensors, block airflow to turbine blades, and damage the cockpit’s visibility.
Indonesia’s Volcanic Activity
Indonesia is part of the Pacific Ring of Fire and the Alpide Belt, which means it is a hotspot for eruptions. There are approximately 130 active volcanoes in the region. Mount Lewotobi Laki Laki erupted in May and March this year.
In November, an eruption caused fatalities and injuries near the volcano. The area’s residents have adapted to the frequent seismic activity, yet the danger remains.
The aviation and travel industries are closely monitoring these events, adapting to ensure safety and minimize disruptions in the face of volcanic activity.
