According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the height of the ash column was observed to reach None meters above the peak (None meters above sea level).

The eruption was not visually observed. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 125 seconds.

According to the MAGMA Indonesia volcanic activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on January 8, 2025, from 00:00 to 23:59 WIB showed 43 eruption quakes with amplitudes of 10-22 millimeters and durations of 66-231 seconds.

Furthermore, there were 3 rockfall quakes with amplitudes of 6-8 mm and durations of 27-62 seconds, and 8 emission quakes with amplitudes of 4-8 millimeters and durations of 39-98 seconds.

The PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 kilometers from the peak (eruption center). Outside this distance, the public should not engage in activities within 500 meters of the riverbank (river buffer zone) along Besuk Kobokan due to the potential for pyroclastic flow and lava flows extending up to 17 kilometers from the peak.

During 2025, MAGMA Indonesia has recorded 174 volcanic eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 120 eruptions.
