Mount Semeru Erupts Again This Morning (Wednesday, April 24, 2024)

Mount Semeru in East Java erupted again on Wednesday, April 24, 2024, at 05:47 WIB (Western Indonesian Time). This marks the third eruption in the past week.

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 at approximately 600 meters above the peak (4,276 meters above sea level).

The ash column was observed to be white to gray in color 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 from April 24, 2024, 18:00-23:59 WIB, showed 9 eruption quakes with amplitudes of 11-22 millimeters and durations of 75-125 seconds.

Furthermore, there was 1 guguran (rockfall) quake with an amplitude of 7 mm and a duration of 93 seconds, and 1 emission quake with an amplitude of 6 millimeters and a duration of 33 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 the expansion of pyroclastic flows and lahars up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 575 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 186 recorded events.
