Mount Semeru in East Java erupted again on Saturday, October 12, 2024, at 09:55 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 43 times.

Based on 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 400 meters above the peak, or 4,076 meters above sea level.

The ash column was observed to be white to gray with moderate intensity towards the southwest. The eruption of Mount Semeru was still ongoing at the time of this report.

According to the MAGMA Indonesia volcanic activity report, the activity level of Mount Semeru is at Level II (Alert). Seismic observations on October 12, 2024, from 00:00 to 23:59 WIB, showed 62 eruption quakes with amplitudes of 10-22 millimeters and durations of 50-181 seconds.

Furthermore, there were 9 guguran (rockfall) quakes with amplitudes of 2-10 mm and durations of 48-145 seconds, and 11 emission quakes with amplitudes of 4-8 millimeters and durations of 44-94 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 lahar flows extending up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 4,429 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (1,821 eruptions), while Mount Semeru erupted 1,479 times.
