Mount Semeru Erupts Again This Morning (Monday, October 28, 2024)

Mount Semeru in East Java erupted again on Monday, October 28, 2024, at 09:51 WIB (Western Indonesian Time). This was the third eruption in the last week.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the ash column was observed to be approximately 800 meters above the peak, or 4,476 meters above sea level.

The ash column was observed to be white to gray in color with thick intensity towards the west. The eruption was recorded on a seismograph with a maximum amplitude of 23 millimeters and a duration of 119 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 October 28, 2024, showed 75 eruption quakes with amplitudes of 11-22 millimeters and durations of 60-171 seconds.

Furthermore, there were 11 rockfall quakes with amplitudes of 2-8 mm and durations of 45-101 seconds, and 14 emission quakes with amplitudes of 3-8 millimeters and durations of 44-77 seconds.

The PVMBG advises against any activity in the southeastern 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 edge) 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 4,610 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (1,876 eruptions), while Mount Semeru erupted 1,537 times.
