Based on 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 be approximately 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 98 seconds.

According to the MAGMA Indonesia volcano activity report, the activity level of Mount Semeru is at Level II (Alert). Observations of seismic activity on January 28, 2025, from 00:00 to 23:59 WIB, showed 44 eruption quakes with amplitudes of 10-23 millimeters and durations of 56-224 seconds.

Furthermore, there was 1 rockfall earthquake with an amplitude of 5 mm and a duration of 32 seconds, and 13 emission quakes with amplitudes of 3-8 millimeters and durations of 37-88 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 8 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 13 kilometers from the peak.

During 2025, MAGMA Indonesia has recorded 820 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 391 eruptions.
