JAKARTA – Mount Lewotobi Laki‑Laki, on Flores Island in East Nusa Tenggara province, erupted on June 17, projecting an ash column up to 11 km (7 miles) into the atmosphere. The country’s volcanology agency immediately elevated the alert to Level 4 – the highest tier. Additional eruptions on June 18 sent further ash approximately 1 km high, expanding the alert zone and prompting evacuation orders.

Villages including Boru, Hewa, Watobuku, and Nurabelen experienced ash, gravel, and sandfall. Residents were evacuated to safer areas, though no casualties have been reported. Authorities also issued warnings about potential lahars—mudflows that may wash down during heavy rains.

Dozens of Flights Cancelled, Several Airports Closed

The ash cloud disrupted flights between Australia, India, Singapore, China, and New Zealand and Bali. Airlines affected include Singapore Airlines, Scoot, Air India, Jetstar, Qantas, Virgin Australia, Air New Zealand, and Juneyao Airlines.

Bali’s Ngurah Rai International Airport reported 32 cancelled flights, while regional airports—including Fransiskus Xaverius Seda in Maumere—were closed June 18–19 for safety inspections. Airlines like Jetstar expect delays to resolve by late evening, pending ash dispersal.

Regional Impact and Context

– This is the volcano’s third eruption in six months, following events in March and May, each prompting elevated alert status.
– The 2024 eruption in November caused nine fatalities and displacement of thousands, underscoring the volcano’s volatility .
– Indonesia, sitting on the Pacific Ring of Fire, has over 120 active volcanoes, making such events common and often hazardous.

Government Response and Public Safety Measures

The National Disaster Management Agency (BNPB) widened the exclusion zone to 8 km around the volcano, issued evacuation orders, and cautioned residents to avoid ash-contaminated zones. Local disaster officials confirmed residents evacuated from two villages, with streets blanketed in volcanic debris. The BNPB and geology agency continue to closely monitor seismic activity and ash plume movements.

Outlook for Travelers

Ngurah Rai and other airlines have updated advisories: travellers should check flight status frequently, and be prepared for delays or re-bookings. Ash is expected to clear by tonight, but further eruptions remain possible.

The ongoing activity at Mount Lewotobi Laki‑Laki demands vigilance. Authorities continue hazard assessments, and residents and tourists are urged to adhere to exclusions, monitor official channels, and stay alert as ash clouds persist and additional eruptions could occur. (zai) – Photo: REUTERS
