Mount Lewotobi Laki-Laki, located in East Nusa Tenggara, Indonesia, erupted violently on Tuesday, 17 June 2025, spewing an ash cloud that reached up to 11 kilometres (approximately 6.8 miles) into the atmosphere. The eruption prompted the authorities to raise the volcano’s alert status to the highest level. This also prompted the evacuation of nearby residents and significant disruption to air travel. As reported by Hindustan Times and Udayavani, the eruption affected both the local community and international flights, including those bound for Bali.
Highest Alert Issued After Mount Lewotobi Laki-Laki Erupts
The Indonesian Geological Agency raised the volcano’s alert level to Level IV, the highest possible, following the eruption. As per Udayavani, authorities instructed residents living within an eight-kilometre radius of the crater to evacuate immediately due to the risks of further eruption and falling ash. The Mount Lewotobi Laki-Laki eruption marks one of the most intense volcanic events in the region in recent months, with ash cloud visibly blanketing nearby villages and agricultural areas.
Air Travel Disruption
The powerful ash plume triggered significant flight cancellations and delays, particularly on routes to and from Bali. According to Hindustan Times, several airlines suspended operations due to low visibility and potential hazards from Laki-Laki Volcano ash. The plume, which reached up to 11 kilometres into the sky, posed a serious threat to aviation safety and air quality across affected areas.
Safety Measures And Ongoing Monitoring
Authorities set up exclusion zones and began relocating residents from the danger zone after the volcanic eruption. Media reports suggest that emergency response teams have been stationed in affected districts, and shelters have been prepared for displaced families. Though no injuries have been confirmed, officials continue to monitor the situation closely for any further volcanic activity. The Indonesian Meteorology, Climatology and Geophysical Agency remains on high alert and has advised locals to stay vigilant.
