Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the ash column height was observed to be approximately 1,000 meters above the peak (2,325 meters above sea level).

The ash column was observed to be gray with thick intensity towards the west. The eruption was recorded on a seismograph with a maximum amplitude of 28 millimeters and a duration of 178 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Ibu's activity level is at Level III (Alert). Observations of seismic activity on January 29, 2025, from 6:00 AM to 12:00 PM WIT showed 17 eruption quakes with amplitudes of 23-28 millimeters and durations of 40-85 seconds.

Furthermore, there were 16 tremor quakes with amplitudes of 2-17 millimeters and durations of 21-59 seconds, and 8 harmonic tremors with amplitudes of 2-4 millimeters and durations of 39-79 seconds.

PVMBG advises the public around Mount Ibu and visitors/tourists not to engage in activities within a 4-kilometer radius and a 5-kilometer sectoral expansion towards the crater opening in the northern part of Mount Ibu's active crater.

During 2025, MAGMA Indonesia has recorded 849 volcanic eruptions throughout Indonesia. Mount Semeru in East Java had the most eruptions (410 times), while Mount Ibu erupted 380 times.
