Mount Semeru in East Java erupted again on Saturday, June 15, 2024, at 7:47 AM WIB. In the last week, Mount Semeru has erupted 93 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the ash column height was observed to be approximately 700 meters above the peak or 4,376 meters above sea level.

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

According to the MAGMA Indonesia volcanic activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations from June 15, 2024, 00:00-06:00 AM WIB, showed 51 eruption quakes with amplitudes of 16-23 millimeters and durations of 85-154 seconds.

Furthermore, there were 20 rockfall quakes with amplitudes of 2-4 mm and durations of 42-80 seconds, and 3 emission quakes with amplitudes of 3-4 millimeters and durations of 35-60 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 margin) 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 1,120 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 487 recorded.
