According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on September 11, 2024, from 00.00 to 23.59 WIB showed 86 eruption quakes with amplitudes of 10-22 millimeters and durations of 53-182 seconds.

Furthermore, there were 2 pyroclastic flow quakes with amplitudes of 4-5 mm and durations of 52-82 seconds, and 7 tremor quakes with amplitudes of 4-8 millimeters and durations of 47-70 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, people should not engage in activities within 500 meters of the riverbank (river buffer zone) along Besuk Kobokan due to the potential for the expansion of pyroclastic flows and lahars up to 17 kilometers from the summit.
