Mount Semeru in East Java erupted again on Saturday, June 1, 2024, at 7:49 AM WIB. In the last week, Mount Semeru has erupted 13 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 400 meters above the peak (4,076 meters above sea level).

The ash column was observed to be white to gray with moderate intensity towards the south. 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 from June 1, 2024, 00:00-06:00 WIB, showed 11 eruption quakes with amplitudes of 10-22 millimeters and durations of 60-136 seconds.

Furthermore, there was 1 rockfall quake with an amplitude of 2 mm and a duration of 37 seconds, and 7 emission quakes with amplitudes of 5-6 millimeters and durations of 30-81 seconds.

PVMBG advises against any activity in the southeast sector along the Besuk Kobokan River, 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 the Besuk Kobokan River due to the potential for expansion of pyroclastic flows and lahars up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 845 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 336 recorded events.
