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 99 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on September 7, 2024, from 00:00 to 23:59 WIB, showed 98 eruption quakes with amplitudes of 12-23 millimeters and durations of 54-170 seconds.

Furthermore, there were 8 rockfall quakes with amplitudes of 2-10 mm and durations of 48-112 seconds, and 13 emission quakes with amplitudes of 2-8 millimeters and durations of 40-83 seconds.

PVMBG advises against any activity in the southeast sector along the Besuk Kobokan river, 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 along the Besuk Kobokan river due to the potential for pyroclastic flow and lava flows extending up to 17 kilometers from the summit.

During 2024, MAGMA Indonesia has recorded 3,551 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (1,421 eruptions), while Mount Semeru erupted 1,176 times.
