Mount Semeru Erupts Again This Morning, Volcanic Ash Reaches Approximately 600 Meters

Mount Semeru in East Java erupted again on Sunday, August 4, 2024, at 7:48 AM WIB. In the last week, Mount Semeru has erupted 50 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 to reach 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 north and northeast. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 104 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on August 4, 2024, from 00:00 to 23:59 WIB showed 51 eruption quakes with amplitudes of 10-23 millimeters and durations of 62-173 seconds.

Furthermore, there were 5 rockfall quakes with amplitudes of 2-6 mm and durations of 40-65 seconds, and 9 emission quakes with amplitudes of 3-6 millimeters and durations of 30-70 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 2,340 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 806 eruptions.
