According to the MAGMA Indonesia volcanic activity report, the activity level of Mount Semeru is at Level II (Alert). Seismic observations on December 7, 2024, from 00:00 to 23:59 WIB showed 86 eruption quakes with amplitudes of 10-22 millimeters and durations of 62-150 seconds.

Furthermore, there were 2 pyroclastic flow quakes with amplitudes of 2-3 mm and durations of 55-90 seconds, and 18 tremor quakes with amplitudes of 5-8 millimeters and durations of 40-84 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, 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 expansion and lava flows up to 13 kilometers from the peak.
