Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the height of the ash column was observed to reach 800 meters above the peak, or 4,476 meters above sea level.

The ash column was observed to be white to gray with moderate intensity towards the southwest. The eruption of Mount Semeru was still ongoing at the time of this report.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations on April 27, 2024, from 00:00 to 06:00 WIB showed 9 eruption quakes with amplitudes of 14-22 millimeters and durations of 59-182 seconds.

Furthermore, there were 4 puffing quakes with amplitudes of 4-5 millimeters and durations of 55-82 seconds, and 1 harmonic tremor with an amplitude of 9 millimeters and a duration of 165 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 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 and lahar flows extending up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 591 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 196 eruptions.
