Mount Semeru in East Java erupted again on Wednesday, August 28, 2024, at 7:05 PM WIB. In the last week, Mount Semeru has erupted 44 times.

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 a seismograph with a maximum amplitude of 22 millimeters and a duration of 125 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on August 28, 2024, from 00:00 to 23:59 WIB, showed 99 eruption quakes with amplitudes of 10-23 millimeters and durations of 63-179 seconds.

Furthermore, there were 15 rockfall quakes with amplitudes of 2-14 mm and durations of 34-118 seconds, and 14 emission quakes with amplitudes of 4-8 millimeters and durations of 37-58 seconds.

PVMBG advises against any activity in the southeastern sector along Besuk Kobokan, up to 8 kilometers from the summit (eruption center). Outside this distance, the public 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 summit.

During 2024, MAGMA Indonesia has recorded 3,193 volcanic eruptions across Indonesia. Mount Ibu in North Maluku had the most eruptions (1,227 times), while Mount Semeru erupted 1,066 times.
