Mount Semeru in East Java erupted again on Saturday, February 8, 2025, at 00:51 WIB. In the last week, Mount Semeru has erupted 80 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 or None meters above sea level.

The eruption was not visually observed. The eruption was recorded on a seismograph with a maximum amplitude of 21 millimeters and a duration of 103 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 February 8, 2025, from 00:00 to 23:59 WIB showed 54 eruption quakes with amplitudes of 12-23 millimeters and durations of 45-200 seconds.

Then, there were 7 emission quakes with amplitudes of 4-8 millimeters and durations of 37-64 seconds, and 3 harmonic tremors with amplitudes of 6-9 millimeters and durations of 58-215 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 lava flows extending up to 17 kilometers from the peak.

During 2025, MAGMA Indonesia has recorded 1,101 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java had the most eruptions with 566.
