JAKARTA - The Center for Volcanology and Geological Hazard Mitigation (PVMBG) revealed that the energy in the body of magma Mount Lewotobi Men is still ongoing, marked by an eruption that occurs every day.

Head of PVMBG Hadi Wijaya said his party could not provide certainty regarding the decline in status at Mount Lewotobi Men.

"This activity is still ongoing and our equipment continues to record this condition," he said when met during an activity entitled Bimtek, Increasing the Effectiveness of Disaster Risk Communication in Mataram City, West Nusa Tenggara, Tuesday, was confiscated by Antara.

Mount Lewotobi Male is a volcano located in East Flores Regency, East Nusa Tenggara. The 1.584-meter-high mountain above sea level (masl) has an explosive eruption character that produces incandescent material and ash deposits.

From the beginning of 2024 to August 2025, PVMBG has set a alert status or level IV for Men's Lewotobi Mountain.

The phenomenal eruption occurred on August 1, 2025, which spewed a column of ash as high as 18,000 meters. The Himawari weather satellite detected the spread of volcanic ash reaching an altitude of 45,000 feet leading southwest to southeast.

On August 23, 2025, at 18.00 WITA, the status of Mount Lewotobi Men dropped from alert to alert or level III.

Hadi said that after the decline in status the next day, activity rose again and there was an eruption that threw volcanic ash as high as 400 meters, then to 1,000 to 2,000 meters.

Based on input from the PVMBG expert team, level 3 status can still be maintained with the condition of instrumentation tools to monitor the current geological activities.

"We are ready with the conditions whether an increase will be made to level IV if the instrumentation shows an increasing trend," said Hadi.

The Indonesian Magma Portal managed by the Ministry of Energy and Mineral Resources (ESDM) was accessed on August 26, 2025, recording the seismic activity of Mount Lewotobi Men as many as 1 eruption earthquake, 1 avalanche earthquake, 4 gusts earthquakes, 2 non-harmonic tremors, and 1 deep volcanic earthquake.
