- Mount Lewotobi eruption disrupts Bali air travel
- Over 18 km ash plume affects major flight routes
- Ongoing seismic activity poses lahar flood risks
A dramatic eruption from Indonesia's Mount Lewotobi has disrupted international travel, particularly affecting routes between Australia and Bali. On Monday, the volcano released an enormous ash cloud reaching approximately 18 kilometers above its summit, prompting flight cancellations and delays that impacted travelers and aviation operations alike.
Located on the island of Flores, Mount Lewotobi Laki-Laki — one of a twin-volcano system — erupted at 11:05 am local time. According to Indonesia’s volcanology agency, the eruption was highly explosive and continuous seismic activity was recorded in the area. The 1,584-metre-high volcano is part of a pair, with its sister peak, Mount Lewotobi Perempuan, standing slightly taller and generally more dormant.
The disruption primarily affected flights from Australia to Denpasar, Bali. Airlines operating out of Perth and Sydney had to cancel or delay multiple flights as a safety precaution against airborne volcanic ash, which poses a serious threat to aircraft engines. Although there have been no immediate reports of injuries or structural damages, authorities are on high alert due to the possibility of lahar floods. These hazardous flows of volcanic mud and debris are particularly dangerous during rainfall and can impact communities situated near rivers.
The eruption comes just weeks after a similar event caused the cancellation of dozens of flights and evacuation of nearby villages. This time, the ash column’s height and intensity led to swift action by aviation authorities. While such disruptions are inconvenient, safety remains the top priority, especially given the historical volatility of Mount Lewotobi. In November last year, the volcano erupted multiple times, tragically resulting in nine fatalities and forcing thousands to evacuate.
Travel and tourism stocks with ties to the region may experience volatility as a result of the disruptions. Investors tracking companies like Flight Centre Travel Group (ASX:FLT), Corporate Travel Management (ASX:CTD), and Qantas Airways (ASX:QAN) may observe short-term fluctuations based on news developments. Similarly, logistics and airline service providers could also see temporary effects, especially if the volcanic activity continues.
As Indonesia continues to monitor Mount Lewotobi’s status, further updates from geological agencies and aviation authorities are expected. Travellers planning to visit Bali are advised to check for flight updates and stay informed on the latest safety advisories.
