Volcanic activity at Mount Lewotobi Laki-laki in East Nusa Tenggara has again shown a significant increase. On Tuesday (7/7/2026) afternoon at 16:40 WITA, the volcano spewed a column of volcanic ash up to 700 meters above the peak, or approximately 2,284 meters above sea level.
According to a report from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the observed ash column was thick and drifting toward the west and northwest. This eruption was recorded on a seismogram with a maximum amplitude of 10.5 millimeters and lasted for 140 seconds.
Currently, the activity level of Mount Lewotobi Laki-laki remains at Level III (Alert). Seismic observation records show fairly intense activity, where between 06:00 and 12:00 WITA, three eruption earthquakes, two gust earthquakes, and five non-harmonic tremors were detected.
It is noted that in the past week, the volcano has experienced 17 eruptions. Given the high frequency of volcanic activity, PVMBG issued a strict recommendation for local residents and tourists to refrain from any activities within a 5-kilometer radius of the eruption center to anticipate the danger of incandescent material ejecta and pyroclastic flows.
For comparison, throughout 2026 until early July, MAGMA Indonesia recorded 2,986 eruption events across various volcanoes in the country. Mount Lewotobi Laki-laki itself has recorded 331 eruptions so far this year, making it one of the most active volcanoes in Indonesia alongside Mount Semeru.
