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

Mount Semeru in East Java erupted again on Monday, October 28, 2024, at 08.06 WIB (Western Indonesian Time). This marks the second eruption in the past 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 400 meters above the peak, or 4,076 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 18 millimeters and a duration of 98 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.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, within an 8-kilometer radius of the peak (eruption center). Outside this radius, the public should not engage in activities within 500 meters of the riverbank (river boundary) along Besuk Kobokan due to the potential for pyroclastic flow and lava flows extending up to 13 kilometers from the peak.

During 2024, MAGMA Indonesia recorded 4,608 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku experienced the most eruptions (1,876 eruptions), while Mount Semeru erupted 1,536 times.
