Volcanic activity at Mount Lewotobi Laki-laki in East Flores Regency, East Nusa Tenggara, has reportedly experienced another significant increase. On Tuesday afternoon (7/7/2026), the volcano spewed a thick volcanic ash column approximately 1.4 kilometers above the crater peak.
The Geological Agency of the Ministry of Energy and Mineral Resources recorded the eruption at 11:37 AM WITA. The thick gray ash column was observed moving west to northwest. According to seismographic data, this eruption was recorded with a maximum amplitude of 47.3 millimeters and a duration of 87 seconds.
Currently, the volcano's status remains at Level III (Alert). Members of the public and tourists are strictly prohibited from conducting any activities within a 5-kilometer radius of the eruption center to anticipate the danger of unexpected volcanic material ejection.
In addition to the threat of direct eruption, authorities have also issued a serious warning regarding the risk of rain-triggered lahar (mudflow) floods, particularly for residents living along river basins originating from Mount Lewotobi Laki-laki. Areas such as Dulipali, Padang Pasir, Nobo, Nurabelen, Klatanlo, Hokeng Jaya, Boru, and Nawakote have been urged to remain highly vigilant.
Regarding exposure to volcanic ash which can impact health, people located in the path of the ash distribution are advised to wear masks as a respiratory protection measure. The East Flores Regional Government is expected to strengthen coordination with the Mount Lewotobi Laki-laki Monitoring Post to ensure the rapid, accurate, and reliable dissemination of mitigation information to the wider community.
