According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations on February 24, 2026 from 06:00-12:00 WIB showed 22 eruption/explosion earthquakes with amplitudes of 15-22 millimeters and durations of 60-131 seconds.

Additionally, there were 3 collapse earthquakes with amplitudes of 2-5 mm and durations of 25-63 seconds, as well as 1 emission earthquake with an amplitude of 5 millimeters and a duration of 57 seconds.

PVMBG advises against any activities in the southeast sector along Besuk Kobokan, within 13 kilometers of the peak (eruption center). Beyond this distance, residents should avoid activities within 500 meters of the riverbanks along Besuk Kobokan due to the potential for being affected by expanding pyroclastic flows and lahar flows up to 17 kilometers from the peak.

In 2026, MAGMA Indonesia has recorded 753 volcanic eruptions across Indonesia. Mount Semeru in East Java has the highest number of eruptions with 394 events.
