Mount Semeru Erupts Again Tonight (Saturday, December 21, 2024)

Mount Semeru in East Java erupted again on Saturday, December 21, 2024, at 00:26 WIB. In the last week, Mount Semeru has erupted 43 times.

Based on 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 visual eruption was not observed. The eruption was recorded on the seismograph with a maximum amplitude of 22 millimeters and a duration of 110 seconds.

According to the MAGMA Indonesia volcano activity report, the activity level of Mount Semeru is at Level II (Alert). Observations of seismic activity on December 21, 2024, from 00:00 to 23:59 WIB showed 58 eruption quakes with amplitudes of 10-22 millimeters and durations of 55-241 seconds.

Furthermore, there were 9 emission quakes with amplitudes of 4-8 millimeters and durations of 43-96 seconds, and 4 harmonic tremors with amplitudes of 6-12 millimeters and durations of 109-315 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 engage in activities within 500 meters of the riverbank (river boundary) along Besuk Kobokan due to the potential for the expansion of pyroclastic flows and lava flows up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia recorded 6,012 volcanic eruptions/eruptions throughout Indonesia. Mount Ibu in North Maluku had the most eruptions (2,486 eruptions), while Mount Semeru erupted 2,140 times.
