According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations on March 6, 2026 from 12:00-18:00 WIB showed 13 eruption/explosion earthquakes with an amplitude of 10-22 millimeters and a duration of 61-131 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 should not carry out activities within 500 meters of the riverbank along the Besuk Kobokan due to the potential for being affected by expanding hot clouds and lava flows up to 17 kilometers from the peak.
