Volcanic activity at Mount Lewotobi Laki-laki in East Nusa Tenggara has once again shown a significant increase. The volcano reportedly erupted on Wednesday (8/7/2026) afternoon at 17:26 WITA, adding to the long list of seismic activity occurring in the region over the past week.
Based on data from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the eruption's ash column was observed rising up to 800 meters above the mountain peak, or about 2,384 meters above sea level. The volcanic material was observed to be gray with a thick intensity, moving toward the west and northwest. Seismographs recorded this eruption with a maximum amplitude of 22.2 millimeters and a duration of 154 seconds.
To date, the status of Mount Lewotobi Laki-laki remains at Level III (Alert). Based on monitoring records between 12:00 and 18:00 WITA, officials recorded high seismic intensity, including seven eruption earthquakes, ten emission earthquakes, and twelve non-harmonic tremor earthquakes.
In response to these conditions, PVMBG strongly advises the public, local residents, and tourists not to carry out any activities within a 5-kilometer radius of the eruption center. This warning is aimed at mitigating the direct risks from volcanic projectile ejecta and pyroclastic flows.
MAGMA Indonesia data shows that throughout 2026, Mount Lewotobi Laki-laki has been recorded to erupt 351 times. This figure is part of a total of 3,031 volcanic eruptions that occurred across Indonesia during the same period, with Mount Semeru in East Java being the volcano with the highest number of eruptive activities.
