Volcanic activity at Mount Lewotobi Laki-Laki increased significantly again on Tuesday (7/7/2026). The Center for Volcanology and Geological Hazard Mitigation (PVMBG) recorded the eruption taking place at exactly 11:37 AM WITA, sending a thick gray ash column soaring 1,400 meters above the peak, or reaching 2,984 meters above sea level. The eruption was recorded on a seismograph with a maximum amplitude of 47.3 millimeters lasting for 87 seconds.
Victorio Antonius, an officer at the Mount Lewotobi Laki-Laki Monitoring Post, urged local residents and tourists to immediately stay away from the danger zone within a 5-kilometer radius from the center of the eruption. The public is asked to remain calm, avoid being easily influenced by misinformation, and always follow official directives from the local government for mutual safety.
In addition to the threat of volcanic ash affecting respiratory health, authorities also issued an early warning regarding the potential for rain-triggered lahar floods. This potential hazard primarily threatens areas along river basins originating from the peak, such as the regions of Dulipali, Padang Pasir, Nobo, Nurabelen, Klatanlo, Hokeng Jaya, Boru, and Nawakote, especially during periods of heavy rainfall.
Throughout 2026, Mount Lewotobi Laki-Laki has erupted 428 times. To date, the volcano remains at Alert Level III (Siaga). Based on observation data from 06:00 to 12:00 WITA, volcanic activity intensity remains quite high, encompassing various types of tremors including eruptions, exhalations, and non-harmonic tremors indicating ongoing volcanic pressure.
