Warning! Mount Semeru Erupts Again Early This Morning (Monday, January 13, 2025)

Mount Semeru in East Java erupted again on Monday, January 13, 2025, at 03:36 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 22 times.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the height of the ash column was observed at approximately None meters above the peak (None meters above sea level).

The eruption was not visually observed. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 164 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level II (Alert). Observations of seismic activity on January 13, 2025, from 00:00 to 23:59 WIB, showed 65 eruption quakes with amplitudes of 10-22 millimeters and durations of 54-171 seconds.

Furthermore, there were 5 emission quakes with amplitudes of 3-6 millimeters and durations of 46-72 seconds, and 2 harmonic tremors with amplitudes of 3-5 millimeters and durations of 76-140 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 8 kilometers from the peak (eruption center). Outside this distance, the public 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 13 kilometers from the peak.

During 2025, MAGMA Indonesia has recorded 277 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 171 eruptions.
