Volcanic activity at Mount Lewotobi Laki-Laki in East Flores Regency, East Nusa Tenggara, has shown a significant escalation. As of Tuesday (7/7/2026) afternoon, the volcano recorded eight eruptions with ash columns reaching up to 1,400 meters above the peak.
In response to these conditions, the Geological Agency, through the Center for Volcanology and Geological Hazard Mitigation (PVMBG), issued a strict warning for local residents and tourists. Authorities strictly prohibit any activities within a 5-kilometer radius of the eruption center to mitigate life-threatening risks from volcanic ejecta and pyroclastic flows.
According to the latest report, a thick gray ash column was observed moving west and northwest. The latest eruption recorded at 16:40 WITA lasted 140 seconds with a seismic amplitude reaching 10.5 mm. The Geological Agency urged residents to remain calm, avoid unverified rumors, and follow official instructions from local authorities.
In addition to eruption hazards, communities along river basins originating from Mount Lewotobi, such as in the Dulipali, Nobo, and Hokeng Jaya areas, are advised to heighten vigilance against potential rain-triggered lahar floods, especially during heavy rainfall. Residents affected by volcanic ashfall are also required to wear face masks as basic protection against respiratory issues.
Local governments are urged to maintain close coordination with the Mount Lewotobi Laki-Laki Observation Post in Pululera Village. PVMBG assured that it will continue to provide regular updates to ensure the safety of communities in the disaster-prone zone.
