Mount Semeru Erupts Again This Morning, Volcanic Ash Reaches 1,000 Meters Above the Peak

Mount Semeru in East Java erupted again on Tuesday, February 6, 2024, at 7:30 AM WIB. In the last week, Mount Semeru has erupted 7 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 be approximately 1,000 meters above the peak or 4,676 meters above sea level.

The ash column was observed to be white, gray to brown with thick intensity towards the northeast. The eruption was recorded on a seismograph with a maximum amplitude of 23 millimeters and a duration of 120 seconds.

According to the MAGMA Indonesia volcanic activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on February 6, 2024, from 00:00 to 06:00 AM WIB showed 29 eruption quakes with amplitudes of 12-22 millimeters and durations of 95-125 seconds.

Furthermore, there was 1 rockfall earthquake with an amplitude of 13 mm and a duration of 60 seconds, and 3 emission quakes with amplitudes of 6-9 millimeters and durations of 16-41 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 hot cloud expansion and lava flows up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 153 volcanic eruptions/eruptions throughout Indonesia. Mount Lewotobi Laki-laki in East Nusa Tenggara had the most eruptions (53 times), while Mount Semeru erupted 32 times.
