Mount Semeru in East Java erupted again on Sunday, October 20, 2024, at 6:50 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 20 times.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the ash column height was observed to reach 700 meters above the peak (4,376 meters above sea level).

The ash column was observed to be gray with moderate to thick intensity towards the southwest. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 120 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on October 20, 2024, from 00:00 to 23:59 WIB, showed 50 eruption quakes with amplitudes of 10-23 millimeters and durations of 57-230 seconds.

Furthermore, there were 4 rockfall quakes with amplitudes of 2-10 mm and durations of 41-75 seconds, and 14 tremor quakes with amplitudes of 2-8 millimeters and durations of 29-82 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 the expansion of pyroclastic flows and lava flows up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 4,513 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (1,838 eruptions), while Mount Semeru erupted 1,511 times.
