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 or None meters above sea level.

The visual eruption was not observed. The eruption was recorded on a seismograph with a maximum amplitude of 23 millimeters and a duration of 119 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on March 7, 2025, from 00:00 to 23:59 WIB, showed 67 eruption quakes with amplitudes of 10-23 millimeters and durations of 50-291 seconds.

Furthermore, there were 12 puffing quakes with amplitudes of 2-8 millimeters and durations of 37-76 seconds, and 1 harmonic tremor with an amplitude of 3 millimeters and a duration of 177 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 conduct 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 2025, MAGMA Indonesia has recorded 1,944 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java had the most eruptions, with 916.
