Mount Semeru in East Java erupted again on Saturday, December 28, 2024, at 12:50 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 72 times.

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 or None meters above sea level.

The eruption was not visually observed. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 160 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 28, 2024, from 00:00 to 23:59 WIB, showed 45 eruption quakes with amplitudes of 12-22 millimeters and durations of 55-205 seconds.

Furthermore, there were 10 puffing quakes with amplitudes of 3-8 millimeters and durations of 41-93 seconds, and 2 harmonic tremors with amplitudes of 4-11 millimeters and durations of 93-233 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 boundary) 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 6,141 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (2,526 eruptions), while Mount Semeru erupted 2,221 times.
