Mount Semeru in East Java erupted again on Saturday, March 1, 2025, at 03:05 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 116 times.

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 at approximately 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 111 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 1, 2025, from 00:00 to 23:59 WIB, showed 53 eruption quakes with amplitudes of 10-23 millimeters and durations of 49-165 seconds.

Then, there were 10 puffing quakes with amplitudes of 3-8 millimeters and durations of 35-76 seconds, and 2 deep volcanic quakes with amplitudes of 18-20 millimeters, s-p 1.28-2 seconds, and durations of 5-19 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, people should not engage in activities within 500 meters of the riverbank (river boundary) 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 1,753 volcanic eruptions throughout Indonesia. Mount Semeru in East Java had the most eruptions, with 830.
