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 at approximately None meters above the peak (None meters above sea level).

The eruption was not visually observed. The eruption of Mount Semeru was still ongoing at the time of this report.

According to the MAGMA Indonesia volcano activity report, the activity level of Mount Semeru is at Level II (Alert). Observations of seismic activity on March 24, 2025, from 00:00 to 23:59 WIB, showed 54 eruption quakes with amplitudes of 10-23 millimeters and durations of 61-176 seconds.

Then, there were 2 pyroclastic flow quakes with amplitudes of 4-6 mm and durations of 56-86 seconds, and 12 tremors with amplitudes of 3-8 millimeters and durations of 34-82 seconds.

PVMBG advises against any activity in the southeastern 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 the expansion of pyroclastic flows and lahars up to 13 kilometers from the peak.

During 2025, MAGMA Indonesia has recorded 2,379 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java had the most eruptions with 1,093.
