The visual eruption was not observed. The eruption was recorded on the seismograph with a maximum amplitude of 22 millimeters and a duration of 98 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 January 26, 2025, from 00:00 to 23:59 WIB showed 64 eruption quakes with amplitudes of 10-23 millimeters and durations of 60-165 seconds.

Then, there was 1 rockfall earthquake with an amplitude of 6 mm and a duration of 55 seconds, and 9 emission quakes with amplitudes of 4-8 millimeters and durations of 20-56 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 carry out activities within 500 meters of the riverbank (river buffer zone) along Besuk Kobokan due to the potential for the expansion of pyroclastic flows and lava flows up to 17 kilometers from the peak.

During 2025, MAGMA Indonesia has recorded 756 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has erupted the most, with 369 eruptions.
