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 92 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on March 17, 2024, from 12:00 to 18:00 WIB, showed 28 eruption quakes with amplitudes of 10-22 millimeters and durations of 45-120 seconds.

Furthermore, there was 1 harmonic tremor with an amplitude of 2 millimeters and a duration of 229 seconds, and 1 deep volcanic earthquake with an amplitude of 10 millimeters, S-P 3.5 seconds, and a duration of 30 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, 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 lahar flows extending up to 17 kilometers from the summit.

During 2024, MAGMA Indonesia has recorded 412 volcanic eruptions across Indonesia. Mount Marapi in West Sumatra had the most eruptions (139 times), while Mount Semeru erupted 119 times.
