Key Takeaways
• Mount Lewotobi Laki Laki erupted on July 7, 2025, sending ash 18 km high, disrupting flights to Bali.
• Ngurah Rai Airport remains open but regional airports Maumere and Larantuka stay closed due to ash.
• Authorities expanded exclusion zone to 7 km; evacuations ongoing amid risks of lahars during rainy season.
A powerful eruption from Mount Lewotobi Laki Laki on Flores Island, Indonesia 🇮🇩, has disrupted travel plans for thousands, grounding flights to Bali and forcing evacuations in nearby villages. The eruption, which began on July 7, 2025, sent a massive ash column high into the sky, raising concerns about aviation safety and the well-being of local communities.
Immediate Impact: Flights to Bali and Regional Disruptions
The eruption started at 11:05 a.m. local time, with Mount Lewotobi Laki Laki spewing ash, rocks, and hot flows down its slopes. The ash cloud reached up to 18 kilometers (11 miles) into the atmosphere, a height that puts it directly in the path of many commercial airplanes. This led to dozens of flight cancellations and delays, especially on routes connecting Bali with Australia, Singapore, and South Korea. Airlines such as Jetstar, Qantas, Indonesia AirAsia, and Virgin Australia were among those most affected.
As of July 8, 2025, Bali’s Ngurah Rai International Airport remained open, but airlines continued to monitor the situation closely. Passengers were urged to check their flight status before heading to the airport, as conditions could change quickly. Meanwhile, airports in Maumere and Larantuka, both in East Nusa Tenggara province, stayed closed due to heavy ash in the air.
Why the Eruption Matters for Travelers and Residents
The eruption of Mount Lewotobi Laki Laki is one of the most significant volcanic events in Indonesia 🇮🇩 since the 2010 Mount Merapi disaster. The ash cloud not only disrupts air travel but also poses health risks for people living nearby. Ash can damage airplane engines, reduce visibility, and make runways slippery, which is why airlines take no chances when a volcano erupts.
For residents, the eruption brought darkness for up to half an hour as ash blanketed villages, covering homes and roads. Authorities doubled the exclusion zone around the volcano to 7 kilometers (4.3 miles), warning everyone inside this area to evacuate immediately. The risk of lahars—dangerous mudflows triggered by rain mixing with volcanic ash—remains high, especially during Indonesia’s rainy season.
Official Responses and Safety Measures
Indonesia’s volcano monitoring agency, PVMBG, had already raised the alert level for Mount Lewotobi Laki Laki to its highest setting in June 2025, after noticing more earthquakes and swelling of the ground. After the July 7 eruption, the agency kept the highest alert in place and expanded the exclusion zone. Local authorities and the National Disaster Mitigation Agency (BNPB) coordinated evacuations and provided updates to the public.
Muhammad Wafid, Chief of Indonesia’s Geology Agency, stressed the ongoing danger to both aviation and people living near the volcano. He said the exclusion zone might need to be expanded again if the volcano stays active. Ahmad Syaugi Shahab, spokesperson for Bali’s Ngurah Rai International Airport, confirmed that the airport was operating normally as of July 8 but was under close watch.
Airlines affected by the eruption, including Virgin Australia, Qantas, and Jetstar, said they were putting passenger safety first. They promised to keep travelers informed and to help with rebooking or refunds for canceled flights.
How Travelers Can Respond: Practical Steps
If you have travel plans involving Bali or other parts of Indonesia 🇮🇩, it’s important to stay informed and flexible. Here are some steps you can take:
- Check your airline’s website or app for the latest updates on your flight status.
- Contact your airline directly if your flight is canceled or delayed. Most airlines are offering rebooking or refunds for affected travelers.
- Monitor local news and official advisories from agencies like PVMBG and BNPB for updates on airport closures and safety warnings.
- Follow evacuation orders if you are in or near the exclusion zone around Mount Lewotobi Laki Laki. Listen to local authorities and use official channels for information.

Background: Mount Lewotobi Laki Laki’s Volcanic History
Mount Lewotobi Laki Laki is part of a twin-volcano system on Flores Island, with a long history of eruptions. The current phase of activity began in late 2023, and a major eruption in November 2024 caused at least nine deaths and injured dozens more. Since then, the volcano has remained restless, with frequent small eruptions and earthquakes.
Indonesia 🇮🇩 sits on the Pacific “Ring of Fire,” a region known for frequent earthquakes and volcanic eruptions. The country has more active volcanoes than any other in the world, and eruptions often disrupt air travel, agriculture, and daily life. The government has invested heavily in monitoring and early warning systems, but the unpredictable nature of volcanoes means that sudden eruptions can still catch people off guard.
Aviation Safety: Why Volcanic Ash Is So Dangerous
Volcanic ash is made up of tiny, sharp pieces of rock and glass. When a volcano like Mount Lewotobi Laki Laki erupts, the ash can rise high into the sky and drift for hundreds of kilometers. If airplanes fly through an ash cloud, the ash can damage engines, clog air filters, and scratch windows, making it unsafe to fly.
That’s why airlines and airport authorities take immediate action when a volcano erupts. They use satellite images, weather reports, and ground observations to track the ash cloud and decide whether it’s safe to fly. In this case, the ash from Mount Lewotobi Laki Laki reached heights that overlap with the cruising altitude of many international flights, forcing airlines to cancel or reroute flights as a precaution.
Impact on Local Communities: Evacuations and Health Risks
For people living near Mount Lewotobi Laki Laki, the eruption brought sudden changes. Ashfall covered homes, roads, and crops, making it hard to breathe and see. Schools and businesses closed, and many families had to leave their homes with little warning. Local health clinics reported an increase in respiratory problems, especially among children and the elderly.
Authorities set up evacuation centers outside the exclusion zone, providing food, water, and medical care. Volunteers and aid groups helped distribute masks and clean water to affected villages. While no deaths were reported from the July 7 eruption, memories of the deadly November 2024 eruption remain fresh in people’s minds.
Travel Advice: What International Visitors Should Know
As of July 11, 2025, the UK Foreign, Commonwealth and Development Office (FCDO) had not issued new travel warnings for Indonesia 🇮🇩 related to this eruption. However, travelers are advised to:
- Stay in touch with their airline for updates on flight schedules.
- Register with their embassy or consulate if staying in affected areas.
- Follow local news and official advisories for the latest information on volcanic activity and safety measures.
Travel insurance policies may cover disruptions caused by natural disasters, but coverage varies. It’s a good idea to check your policy and contact your insurer if your travel plans are affected.
Long-Term Outlook: What Comes Next for Mount Lewotobi Laki Laki and Bali
The situation around Mount Lewotobi Laki Laki remains uncertain. The volcano is still active, with ongoing emissions and the risk of further eruptions. Authorities are prepared to adjust exclusion zones and airport operations as needed, based on the latest data from PVMBG and weather agencies.
For Bali, a popular tourist destination, the eruption is a reminder of the region’s vulnerability to natural disasters. While the island’s main airport was not directly affected by ashfall as of July 8, airlines and airport officials remain on high alert. The tourism industry, which relies on steady air traffic, is watching the situation closely.
Expert Opinions: Balancing Safety and Travel Needs
Experts agree that safety must come first when dealing with volcanic eruptions. Muhammad Wafid, Chief of Indonesia’s Geology Agency, said, “The danger to aviation is real, and we must be ready to expand the exclusion zone if the volcano stays active.” Airline representatives echoed this view, saying that they would rather cancel flights than risk passenger safety.
Ahmad Syaugi Shahab, spokesperson for Bali’s Ngurah Rai International Airport, said, “We are operating normally for now, but we are watching the situation very closely. Passengers should check with their airlines before traveling.”
How Authorities Are Helping: Coordination and Communication
Indonesia’s disaster response agencies have worked quickly to coordinate evacuations and provide information to the public. The PVMBG issues regular updates on volcanic activity, while the BNPB manages emergency shelters and aid distribution. Airlines have set up hotlines and online resources to help travelers rebook flights or get refunds.
Local governments have also played a key role, sending teams to affected villages to help with evacuations and distribute supplies. Community leaders are working to keep people calm and informed, reminding everyone to follow official instructions and avoid rumors.
What This Means for Immigration and International Mobility
