LABUAN BAJO - Geological Agency of the Ministry of Energy and Mineral Resources (ESDM) said the results of visual and instrumental analysis showed that the activities of the Lewotobi Laki Volcano in East Flores Regency, East Nusa Tenggara (NTT) increased.
"So the level of activity of the Men's Lewotobi Volcano is still at Level IV (Awas)," said Head of the Geological Agency Muhammad Wafid as reported by ANTARA, Wednesday, June 18.
He conveyed this in a special report on the development of the activity of Mount Lewotobi Men Level IV (Awas) on June 18, 2025.
In visual observations in the period 17-18 June 2025 Mount Lewotobi, the man was clearly visible until he was covered in fog.
Observed white, gray and black main crater smoke with a thin, medium to high intensity of about 100-1000 meters from the summit.
"The weather is sunny to cloudy, the wind is weak to moderate to the north, northeast, southwest and west," he said.
Meanwhile, the air temperature was about 19.6-27 degrees Celsius and there was an eruption with a height of 2.000-10,000 meters from the summit, the column of ash from the eruption was gray.
On June 17, 2025, there was an increase in volcanic earthquake activity from 11.30 WITA to 14.00 WITA, which was then followed by an eruption at 17.35 WITA.
"The eruption column reaches an altitude of about 10,000 meters above the peak of the Lewotobi Men's Volcano," he said.
After the first eruption, he continued, it was recorded that there were seven follow-up eruptions as of June 18, 2025 at 06.00 WITA, with an eruption column height ranging from 2,000 to 5,000 meters.
Eruption is explosive in all directions, accompanied by incandescent lava and rumbling sounds with moderate to strong intensity.
"This incident is thought to have occurred due to the demolition of lava piles covering the crater which is a product from the previous eruption period," he explained.

Based on seismic data from 17-18 June 2025 at 06.00 WITA, there were eight eruptions, one avalanche earthquake, 13 gusts, 15 non-harmonic tremors, three low-frequency earthquakes.
Then one shallow volcanic earthquake, 75 deep volcanic earthquakes, five distant tectonic earthquakes, and continuous tremors with a dominant amplitude of 3.7 mm.
From the thitmeter and GPS deformation data, it shows indications of inflation as well as InSAR data in line with these data showing inflation anomalies.
"This indicates pressure from within the volcano which can potentially become an eruption," he said.
Because the activity level of Mount Lewotobi Male is still Level IV (Awas), his party appealed to the public and tourists not to carry out activities within a seven km radius and the southwest-northeast sector eight km from the eruption center. "Stay calm and follow directions from the local government," he said.
