Volcanic activity at Mount Lewotobi Laki-Laki in East Flores Regency, East Nusa Tenggara, has shown a significant increase once again. On Monday (6/7/2026) morning at 04:02 WITA, the volcano reportedly erupted, spewing an ash column 1,000 meters above the peak, reaching 2,584 meters above sea level.
According to reports from the Center for Volcanology and Geological Hazard Mitigation (PVMBG), the ash column was observed to be gray with a thick intensity, moving towards the north and northeast. This eruption was recorded on a seismograph with a maximum amplitude of 44.4 mm and lasted for 145 seconds.
An officer at the Mount Lewotobi Laki-Laki Monitoring Post, Fransiskus Masan, urged residents and tourists to comply with the exclusion zone within a 5-kilometer radius of the eruption center. The public is also reminded to remain calm, follow official instructions from the local government, and not be influenced by unverified information.
In addition to the threat of eruption, authorities highlighted the potential danger of cold lava flows (lahars) triggered by rain threatening several areas, such as Dulipali, Padang Pasir, Nobo, Nurabelen, Klatanlo, Hokeng Jaya, Boru, and Nawakote. Residents in these areas are urged to remain vigilant during high-intensity rainfall. People affected by volcanic ash are also required to wear masks to protect their respiratory health.
As of now, Mount Lewotobi Laki-Laki remains at Alert Level III (Siaga). Throughout 2026, a total of 417 eruptions have been recorded. Based on observations on Monday morning, in addition to two eruption earthquakes, a series of other seismic activities were recorded, including gust earthquakes, non-harmonic tremors, low-frequency earthquakes, as well as local and distant tectonic earthquakes, indicating that the volcano's activity remains highly dynamic.
