Mount Semeru Erupts Again in the Early Hours of Today, Eruption Height Approximately 500 Meters

Mount Semeru in East Java erupted again on Sunday, November 3, 2024, at 03:07 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 74 times.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the height of the ash column was observed to reach 500 meters above the peak (4,176 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 118 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 3, 2024, from 00:00 to 23:59 WIB, showed 84 eruption quakes with amplitudes of 10-23 millimeters and durations of 64-192 seconds.

Furthermore, there were 5 rockfall quakes with amplitudes of 3-6 mm and durations of 42-92 seconds, and 19 emission quakes with amplitudes of 3-8 millimeters and durations of 37-75 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, 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 lava flows extending up to 13 kilometers from the peak.

During 2024, MAGMA Indonesia recorded 4,740 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (1,913 eruptions), while Mount Semeru erupted 1,608 times.
