Mount Lewotobi Laki-Laki, located in East Nusa Tenggara, showed significant volcanic activity again on Monday, July 6, 2026, in the early hours. Based on monitoring data, the volcano spewed a thick gray ash column reaching a height of 500 meters from the peak, or about 2,084 meters above sea level, at 00:59 WITA.
The Center for Volcanology and Geological Hazard Mitigation (PVMBG) recorded that this eruption lasted for 46 seconds with a maximum amplitude of 18.5 mm. The spread of volcanic ash material was observed moving toward the north to northeast; thus, residents exposed to ashfall are urged to immediately wear masks to minimize the risk of respiratory issues.
To avoid fatal impacts, authorities have established a sterile zone prohibiting public and tourist activities within a 5-kilometer radius from the eruption center. In addition to the threat of ejected material, the government also emphasized high vigilance regarding the potential for rain-triggered lahar floods that risk hitting river channels around the Dulipali, Nobo, and Hokeng Jaya areas if rainfall increases.
Currently, intensive coordination continues between the Mount Lewotobi Laki-Laki Observation Post in Pululera Village, PVMBG, and the local Regional Disaster Management Agency (BPBD). The public is asked to remain calm, comply with official instructions from the local government, and not be provoked by unverified rumors.
