Mount Semeru Erupts Again This Morning (Wednesday, May 8, 2024)

Mount Semeru in East Java erupted again on Wednesday, May 8, 2024, at 6:53 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 10 times.

According to 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, or 4,276 meters above sea level.

The ash column was observed to be white to gray with thick intensity towards the northeast. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 112 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on May 8, 2024, from 00:00 to 06:00 WIB showed 10 eruption quakes with amplitudes of 19-22 millimeters and durations of 80-140 seconds.

Furthermore, there were 2 puffing quakes with amplitudes of 7-8 millimeters and durations of 25-36 seconds, and 1 harmonic tremor with an amplitude of 6 millimeters and a duration of 215 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, 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 650 volcanic eruptions across Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 223 recorded events.
