Mount Semeru in East Java erupted again on Sunday (January 28, 2024) at 02:50 WIB. In the last week, Mount Semeru has erupted 28 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the observed ash column height reached 700 meters above the peak (4,376 meters above sea level).

The ash column was observed to be gray with thick intensity towards the northeast. The eruption was recorded on a seismograph with a maximum amplitude of 23 millimeters and a duration of 127 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on January 28, 2024, from 18:00 to 23:59 WIB, showed 12 eruption quakes with amplitudes of 12-22 millimeters and durations of 85-125 seconds.

Then, there were 2 rockfall quakes with amplitudes of 7-8 mm and durations of 42-62 seconds, and 1 harmonic tremor with an amplitude of 6 millimeters and a duration of 179 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 edge) 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 124 volcanic eruptions/eruptions throughout Indonesia. Mount Lewotobi Laki-laki in East Nusa Tenggara had the most eruptions (48 times), while Mount Semeru erupted 19 times.
