Mount Semeru Erupts Again in the Early Hours of Today, Ash Reaches 800 Meters Above the Peak

Mount Semeru in East Java erupted again on Monday, November 25, 2024, at 03:24 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 12 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the observed ash column height reached 800 meters above the peak (4,476 meters above sea level).

The ash column was observed to be white to gray with thick intensity towards the southwest. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 117 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on November 25, 2024, from 00:00 to 23:59 WIB, showed 90 eruption quakes with amplitudes of 10-22 millimeters and durations of 63-157 seconds.

Furthermore, there were 2 rockfall quakes with amplitudes of 4-7 mm and durations of 40-43 seconds, and 18 emission quakes with amplitudes of 3-9 millimeters and durations of 24-83 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 8 kilometers from the peak (eruption center). Outside this distance, the public should not carry out 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 13 kilometers from the peak.

During 2024, MAGMA Indonesia recorded 5,393 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (2,199 eruptions), while Mount Semeru erupted 1,841 times.
