Mount Lewotobi Laki-laki, located in East Nusa Tenggara, has once again shown an increase in volcanic activity. On Tuesday (14/7/2026) night at 18:49 WITA, the volcano reportedly erupted again. This eruption adds to a sequence of volcanic activity recorded 16 times over the past week.
Based on data from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia system, an ash column resulting from the eruption was observed approximately 500 meters above the peak, or around 2,084 meters above sea level. The thick gray volcanic ash was observed drifting west and northwest. The eruption was recorded on a seismograph with a maximum amplitude of 22.2 millimeters and a duration of 117 seconds.
Currently, the activity level of Mount Lewotobi Laki-laki remains at Level III (Alert). Seismic reports indicate that within the six-hour period prior to the evening eruption, specifically from 12:00 to 18:00 WITA, three eruption earthquakes occurred with amplitudes ranging between 22.2 and 29.6 millimeters. Additionally, three non-harmonic tremor earthquakes and three low-frequency earthquakes were recorded.
In anticipation of potential follow-up hazards, PVMBG strongly advises local residents, visitors, and tourists to refrain from any activity within a 5-kilometer radius of the eruption center. Compliance with this exclusion zone is crucial to avoid the impact of dangerous volcanic materials that could occur at any time.
Throughout 2026, volcanic activity in Indonesia has been quite high, with a total of 3,179 eruptions recorded across the archipelago. Mount Semeru in East Java ranks first with 1,403 eruptions, while Mount Lewotobi Laki-laki follows in second place with 402 recorded eruptions.
