Mount Semeru Erupts Again Today, Volcanic Ash Reaches 300 Meters

Mount Semeru in East Java erupted again on Wednesday, October 30, 2024, at 01:23 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 19 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 reach 300 meters above the peak, or 3,976 meters above sea level.

The ash column was observed to be white to gray with thick intensity towards the southwest and west. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 123 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on October 30, 2024, from 00:00 to 23:59 WIB, showed 77 eruption quakes with amplitudes of 11-23 millimeters and durations of 59-151 seconds.

Furthermore, there were 12 rockfall quakes with amplitudes of 2-7 mm and durations of 22-109 seconds, and 14 emission quakes with amplitudes of 4-9 millimeters and durations of 29-67 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 kilometers from the peak (eruption center). Outside this distance, the public should not carry out activities within 500 meters of the riverbank (river edge) along Besuk Kobokan due to the potential for pyroclastic flow and lava flows extending up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 4,637 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (1,880 eruptions), while Mount Semeru erupted 1,553 times.
