Mount Semeru Erupts Again Tonight, Eruption Height 400 Meters Above the Peak

Mount Semeru in East Java erupted again on Tuesday, October 22, 2024, at 9:26 PM WIB. In the last week, Mount Semeru has erupted 5 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 400 meters above the peak (4,076 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 124 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 22, 2024, from 00:00 to 23:59 WIB showed 66 eruption quakes with amplitudes of 10-23 millimeters and durations of 59-137 seconds.

Furthermore, there were 6 rockfall quakes with amplitudes of 3-5 mm and durations of 45-85 seconds, and 12 emission quakes with amplitudes of 3-8 millimeters and durations of 37-92 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 (riverbed) 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 has recorded 4,528 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (1,839 eruptions), while Mount Semeru erupted 1,516 times.
