Mount Semeru in East Java erupted again on Tuesday, December 10, 2024, at 10:21 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 31 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the observed ash column height reached None meters above the peak (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 127 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity from 00:00 to 23:59 WIB on December 10, 2024, showed 88 eruption quakes with amplitudes of 10-22 millimeters and durations of 62-200 seconds.

Furthermore, there were 7 rockfall quakes with amplitudes of 4-8 mm and durations of 50-106 seconds, and 11 emission quakes with amplitudes of 4-9 millimeters and durations of 37-77 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 kilometers from the peak (eruption center). Outside this distance, people should not engage in 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 17 kilometers from the peak.

During 2024, MAGMA Indonesia recorded 5,842 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (2,414 eruptions), while Mount Semeru erupted 2,056 times.
