Mount Semeru in East Java erupted again on Sunday (December 8, 2024) at 3:38 PM WIB. In the last week, Mount Semeru has erupted 97 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 eruption was not visually observed. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 115 seconds.

According to the MAGMA Indonesia volcano activity report, the activity level of Mount Semeru is at Level II (Alert). Seismic observations on December 8, 2024, from 00.00 to 23.59 WIB, showed 94 eruption quakes with amplitudes of 12-23 millimeters and durations of 55-160 seconds.

Furthermore, there were 4 rockfall quakes with amplitudes of 3-7 mm and durations of 29-79 seconds, and 20 emission quakes with amplitudes of 3-8 millimeters and durations of 22-120 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, the public 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 lava flows extending up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia recorded 5,800 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (2,398 eruptions), while Mount Semeru erupted 2,032 times.
