Mount Semeru in East Java erupted again on Thursday, May 9, 2024, at 7:04 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 800 meters above the peak or 4,476 meters above sea level.

The ash column was observed to be white to gray with thick intensity towards the south. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 106 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations on May 9, 2024, from 00:00 to 06:00 AM WIB showed 9 eruption quakes with amplitudes of 11-22 millimeters and durations of 100-125 seconds.

Furthermore, there were 2 puffing quakes with amplitudes of 6-9 millimeters and durations of 50-75 seconds, and 1 deep volcanic quake with an amplitude of 8 millimeters, S-P 2.96 seconds, and a duration of 10 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 conduct 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 657 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 226 eruptions.
