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 reach None meters above the peak (None meters above sea level).

The visual eruption was not observed. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 110 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on December 12, 2024, from 00:00 to 23:59 WIB showed 91 eruption quakes with amplitudes of 10-23 millimeters and durations of 40-188 seconds.

Furthermore, there were 2 rockfall quakes with amplitudes of 3-10 mm and durations of 76-87 seconds, and 13 emission quakes with amplitudes of 4-8 millimeters and durations of 45-91 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 lahar flows extending up to 13 kilometers from the peak.

During 2024, MAGMA Indonesia recorded 5,895 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (2,440 eruptions), while Mount Semeru erupted 2,077 times.
