Volcanic activity at Mount Lewotobi Laki-laki in East Nusa Tenggara has once again shown a significant increase. On Wednesday (8/7/2026) at 23:11 WITA, the volcano reportedly erupted again, adding to the long series of eruptions occurring in the region this week.
According to data from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, an ash column was observed rising 300 meters above the peak. Thick grey volcanic material was seen moving toward the west and northwest. The eruption recorded a maximum amplitude of 37 millimeters with a duration of 40 seconds.
Currently, the activity level of Mount Lewotobi Laki-laki remains at Level III (Alert). Seismograph recordings indicate fairly intense seismic activity, including eruption earthquakes, exhalation earthquakes, and non-harmonic tremors. A total of 38 eruptions have been recorded at this mountain in just the past week.
In response to these conditions, PVMBG issued a strict warning to the public, visitors, and tourists to refrain from any activity within a 5-kilometer radius of the eruption center. Authorities emphasized the importance of adhering to this exclusion zone to avoid the harmful impacts of ashfall and potential ejection of volcanic material.
Data from MAGMA Indonesia shows that throughout 2026 until early July, 3,038 volcanic eruptions have occurred across Indonesia. Mount Lewotobi Laki-laki itself has erupted 352 times, making it one of the most active volcanoes in Indonesia during this period of the year.
