Volcanic activity at Mount Lewotobi Laki-laki in East Nusa Tenggara has shown another significant increase. On Monday (13/7/2026) morning, precisely at 07:49 WITA, the volcano was reported to have erupted, spewing a column of ash into the air.
According to an official report 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, equivalent to 1,884 meters above sea level. The observed gray, thick ash column was moving toward the north and northeast. The eruption was recorded by a seismograph with a maximum amplitude of 29.6 millimeters and a duration of 66 seconds.
Currently, the activity status of Mount Lewotobi Laki-laki remains at Level III (Siaga/Alert). Seismic monitoring data recorded from 00:00 to 06:00 WITA indicates intensive activity, including two eruption earthquakes, four emission earthquakes, and one non-harmonic tremor, signaling an ongoing energy supply beneath the crater.
In response to the situation, PVMBG issued strict instructions for local residents, hikers, and tourists. All parties are urged not to conduct any activities within a 5-kilometer radius of the eruption center to avoid the risk of exposure to dangerous volcanic materials.
Nationally, the intensity of volcanic eruptions in Indonesia throughout 2026 has been quite high. A total of 3,144 eruptions have been recorded across various regions. Mount Semeru currently holds the record for the most eruptions with 1,389 times, while Mount Lewotobi Laki-laki itself has recorded 389 eruptions so far this year.
