Warning! Mount Semeru Erupts Again This Morning (Friday, November 29, 2024)

Mount Semeru in East Java erupted again on Friday, November 29, 2024, at 05:47 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 84 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 be approximately 800 meters above the peak or 4,476 meters above sea level.

The ash column was observed to be white to gray with thick intensity towards the northwest. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 109 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 29, 2024, from 00:00 to 23:59 WIB, showed 84 eruption quakes with amplitudes of 12-22 millimeters and durations of 55-135 seconds.

Furthermore, there were 4 rockfall quakes with amplitudes of 3-8 mm and durations of 53-112 seconds, and 18 emission quakes with amplitudes of 4-8 millimeters and durations of 31-59 seconds.

The PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 8 kilometers from the peak (eruption center). Outside this distance, people 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 13 kilometers from the peak.

During 2024, MAGMA Indonesia recorded 5,527 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (2,255 eruptions), while Mount Semeru erupted 1,913 times.
