Mount Lewotobi Laki-laki in East Nusa Tenggara again showed significant volcanic activity on Tuesday (7/7/2026). The eruption, which occurred at 15:18 WITA, produced a volcanic ash column approximately 200 meters above the peak, or about 1,784 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 gray with moderate intensity. The seismograph recorded that this eruption had a maximum amplitude of 10.5 millimeters with an eruption duration of 39 seconds, moving toward the west and northwest.
To date, the volcano's activity status remains set at Level III or Alert. Seismic records indicate fairly intense activity, with a series of eruption quakes, gusts, and non-harmonic tremors detected between 06:00 and 12:00 WITA. In the past week, the volcano has erupted 16 times.
In response to the situation, PVMBG strictly issued a warning to local residents and tourists. People are prohibited from engaging in any activities within a 5-kilometer radius of the eruption center to anticipate potential hazards posed by volcanic materials.
Data from MAGMA Indonesia shows that throughout 2026, Mount Lewotobi Laki-laki has recorded 330 eruptions. This phenomenon adds to the long list of volcanic activity in the country, which has so far recorded nearly 3,000 eruptions across various regions of Indonesia during the current year.
