Volcano Eruption in Indonesia: Mount Lewotobi Laki-Laki Erupts Again
On June 17, 2025, Mount Lewotobi Laki-Laki, located on Flores Island in eastern Indonesia, erupted once again, sending towering columns of ash and smoke into the atmosphere. This eruption has prompted authorities to raise the volcanic alert to its highest level, signaling the potential for further activity and posing significant challenges to local communities and air travel.
Introduction: Understanding the Significance of Mount Lewotobi Laki-Laki
Mount Lewotobi Laki-Laki is a twin-peaked stratovolcano situated in East Nusa Tenggara province. It has been active for several years, with notable eruptions in November 2024 that resulted in fatalities and widespread displacement. The recent eruption on June 17 has intensified concerns due to its magnitude and the potential risks it poses to nearby populations and infrastructure.
Details of the Recent Eruption
Eruption Overview
On June 17, 2025, at approximately 17:35 local time, Mount Lewotobi Laki-Laki erupted, releasing a massive ash cloud that reached altitudes of up to 10,000 meters (32,800 feet). The eruption was characterized by a series of explosive events, ejecting hot ash, gravel, and volcanic gases into the atmosphere. The ash cloud expanded into a mushroom-shaped formation visible from cities located 90 to 150 kilometers away from the volcano .
Impact on Local Communities
The eruption has affected several villages in the vicinity of the volcano, including Boru, Hewa, Watobuku, and Nurabelen. Residents in these areas experienced falling debris and ashfall, prompting local authorities to evacuate populations to safer locations such as Konga and Nileknoheng . As of now, there have been no reported casualties, but the situation remains fluid, and further assessments are underway.
Air Travel Disruptions
Flight Cancellations and Airport Closures
The eruption has significantly disrupted air travel in the region. Major airlines, including Air India, Virgin, Qantas, and Singapore Airlines, have canceled or diverted flights to and from Bali and other nearby airports due to safety concerns related to the ash cloud . Fransiskus Xaverius Seda Airport in Maumere, located approximately 8 kilometers from the volcano, was closed until Thursday for safety reasons .
Broader Aviation Impact
The ash cloud's reach has extended beyond Indonesia's borders, affecting international flights and leading to widespread travel disruptions. Passengers have been stranded at airports, with limited options for rebooking or accommodation. The aviation industry is closely monitoring the situation, and travelers are advised to check with airlines for the latest updates on flight statuses.
Government Response and Preparedness
Alert Levels and Evacuation Measures
In response to the eruption, Indonesia's National Disaster Management Agency (BNPB) has raised the volcanic alert level to the highest tier, Level 4, indicating an imminent or ongoing eruption with significant hazards. An exclusion zone with a radius of 8 kilometers from the crater has been established, and authorities are conducting evacuations from affected areas to mitigate risks associated with lava flows, pyroclastic flows, and potential lahars .
Ongoing Monitoring and Community Support
The government, in collaboration with local agencies, is providing assistance to displaced residents, including temporary shelters, food, and medical care. Efforts are also underway to assess the environmental impact of the eruption, including air quality monitoring and the evaluation of potential agricultural losses. The situation remains dynamic, and authorities continue to monitor the volcano's activity closely.
