Mount Semeru in East Java erupted again on Monday, September 9, 2024, at 6:54 WIB (Western Indonesian Time). In the last week, Mount Semeru had only erupted once.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the visual eruption was not observed. The eruption was recorded on the 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 I (Normal). Observations of seismic activity on September 9, 2024, from 00:00 to 23:59 WIB, showed 95 eruption quakes with amplitudes of 10-23 millimeters and durations of 59-164 seconds.

Furthermore, there were 4 rockfall quakes with amplitudes of 4-10 mm and durations of 40-84 seconds, and 16 emission quakes with amplitudes of 3-8 millimeters and durations of 29-55 seconds.

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

During 2024, MAGMA Indonesia has recorded 3,600 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (1,452 eruptions), while Mount Semeru erupted 1,182 times.
