According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations on May 1, 2024, from 12:00 PM to 6:00 PM WIB showed 8 eruption quakes with amplitudes of 12-22 millimeters and durations of 63-138 seconds.

Furthermore, there was 1 puffing quake with an amplitude of 6 millimeters and a duration of 51 seconds, and 1 deep volcanic quake with an amplitude of 10 millimeters, an S-P time of 3 seconds, and a duration of 20 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, people should not engage in activities within 500 meters of the riverbank (river buffer zone) along the Besuk Kobokan river due to the potential for pyroclastic flow and lava flows extending up to 17 kilometers from the summit.
