Mount Semeru in East Java erupted again on Monday, February 24, 2025, at 11:56 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 37 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 21 millimeters and a duration of 108 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on February 24, 2025, from 00:00 to 23:59 WIB, showed 43 eruption quakes with amplitudes of 11-22 millimeters and durations of 62-230 seconds.

Furthermore, there were 14 puffing quakes with amplitudes of 4-8 millimeters and durations of 35-81 seconds, and 2 harmonic tremors with an amplitude of 5 millimeters and durations of 128-262 seconds.

The PVMBG advises against any activity in the southeast sector along the Besuk Kobokan River, 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 along the Besuk Kobokan River due to the potential for pyroclastic flow and lava flows extending up to 13 kilometers from the peak.

During 2025, MAGMA Indonesia has recorded 1,548 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java had the most eruptions, with 751.
