Mount Semeru in East Java erupted again on Wednesday, May 8, 2024, at 5:43 AM WIB. In the last week, Mount Semeru has erupted 9 times.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the observed ash column reached 600 meters above the peak (4,276 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 volcano activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations on May 8, 2024, from 6:00 PM to 11:59 PM WIB showed 9 eruption quakes with amplitudes of 10-22 millimeters and durations of 63-131 seconds.

Then, there was 1 single rockfall event with an amplitude of 8 mm and a duration of 54 seconds, and 2 emission quakes with amplitudes of 4 millimeters and durations of 30-57 seconds.

PVMBG advises against any activity in the southeastern sector along Besuk Kobokan, within a 13-kilometer radius of the peak (eruption center). Outside this radius, people 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 649 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 222 eruptions.
