According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Earthquake observations on March 10, 2026 from 00:00-06:00 WIB showed 26 eruption/explosion earthquakes with amplitudes of 12-22 millimeters and durations of 60-144 seconds.

PVMBG advises against any activities in the southeast sector along the Besuk Kobokan, within 13 kilometers of the peak (eruption center). Beyond that distance, residents are advised not to carry out activities within 500 meters of the riverbanks along the Besuk Kobokan due to the potential for hot cloud expansion and lahar flows up to 17 kilometers from the peak.

Throughout 2026, MAGMA Indonesia has recorded 937 volcanic eruptions across Indonesia. Mount Semeru in East Java has the highest number of eruptions with 484 events.
