Volcanic activity at Mount Lewotobi Laki-Laki in East Flores Regency, East Nusa Tenggara, has again shown a significant increase. On Saturday (11/7/2026) morning at 08:12 WITA, the volcano reportedly erupted, spewing an ash column 1,000 meters above the crater peak.
According to a report from the Lewotobi Laki-Laki Volcano Monitoring Post (PGA), this eruption was recorded with a maximum amplitude of 44.4 mm. The duration of the eruption lasted for approximately 1 minute 34 seconds, indicating magma movement beneath the crater surface.
PGA Post officer, Bramantya Aji Putra Mahendra, revealed that there are currently lava deposits extending 4,340 meters to the northeast and 3,800 meters to the west from the eruption center. Given these conditions, relevant authorities have strictly prohibited residents and tourists from conducting activities within a 5-kilometer radius of the eruption center.
Observers also issued a special warning regarding the risk of rain-triggered lahar floods in rivers originating from the volcano's peak. Areas such as Dulipali, Padang Pasir, Nobo, Nurabelen, Klatanlo, Hokeng Jaya, Boru, and Nawakote are urged to remain vigilant, especially during heavy rainfall.
As a health mitigation measure, residents exposed to falling volcanic ash are advised to wear masks or mouth and nose protection at all times to prevent respiratory issues. As of now, the status of Mount Lewotobi Laki-Laki remains set at Level III (Alert).
