Citing eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the observed ash column height was approximately 1,500 meters above the peak or 3,084 meters above sea level.

The ash column was observed to be gray with thick intensity towards the north and northwest. The eruption was recorded on a seismograph with a maximum amplitude of 18.5 millimeters and a duration of 72 seconds.

According to the MAGMA Indonesia volcano activity report, the activity level of Mount Lewotobi Laki-laki is at Level III (Alert). Observations of seismic activity on April 24, 2025, from 6:00 PM to 11:59 PM WITA showed 2 instances of puffing earthquakes with amplitudes of 3.7-4.4 millimeters and durations of 56-107 seconds.

Then, there were 6 harmonic tremors with amplitudes of 2.9-7.4 millimeters and durations of 137-154 seconds, as well as 1 distant tectonic earthquake with an amplitude of 22 millimeters, an S-P time of 25 seconds, and a duration of 79 seconds.

PVMBG urges the public around Mount Lewotobi Laki-laki and visitors/tourists not to conduct any activities within a 6-kilometer radius of the eruption center of Mount Lewotobi Laki-laki.
