Mount Lewotobi Laki-Laki Erupts Again, Spews Ash Column 1.4 Kilometres High

Mount Lewotobi Laki-Laki in East Flores, East Nusa Tenggara (NTT), erupted again on Sunday (5/7/2026) morning. The volcano, which is at Level III (Alert) status, erupted at approximately 07.04 WITA.

During the eruption, a thick grey ash column was observed drifting towards the north and northeast. The ash column reached a height of 1,400 metres above the peak, or 2,984 metres above sea level.

“This eruption was recorded on a seismogram with a maximum amplitude of 47.3 mm and a duration of approximately 1 minute 14 seconds,” said Mount Lewotobi Laki-Laki Observation Post Officer, Bramantya Aji Putra M, in an official statement.

Bramantya urged the surrounding community and visitors or tourists not to conduct any activities within a 5-kilometre radius from the eruption centre of Mount Lewotobi Laki-Laki. The public was also advised to remain calm and follow the directives of the East Flores Regency Government and not to believe issues from unclear sources.

“Communities around Mount Lewotobi Laki-Laki should be aware of the potential for rain-triggered lahars in rivers originating at the peak of Mount Lewotobi Laki-Laki if high-intensity rainfall occurs, especially in the areas of Dulipali, Padang Pasir, Nobo, Nurabelen, Klatanlo, Hokeng Jaya, Boru, and Nawakote,” he added.

Bramantya further stated that residents affected by ashfall from Mount Lewotobi Laki-Laki must wear masks or nose-and-mouth coverings to avoid the dangers of volcanic ash to the respiratory system.

“The local government continuously coordinates with the Mount Lewotobi Laki-Laki Observation Post in Pululera Village, Wulanggitang District, East Flores Regency, East Nusa Tenggara Province, or the Centre for Volcanology and Geological Hazard Mitigation, Geological Agency in Bandung,” Bramantya explained.
