Per MAGMA Indonesia volcanic activity reports, Mount Semeru remains at Alert Level III. Seismic monitoring on 13 September 2026 18:00–23:59 WIB recorded 25 eruption earthquakes (10–25 mm amplitude, 79–355 second duration), 10 collapse earthquakes (2–8 mm amplitude, 43–147 second duration), and 6 emission earthquakes (2–9 mm amplitude, 51–166 second duration).
PVMBG prohibits all activities in the southeast sector along the Besuk Kobokan river within 13 km of the summit. Beyond this zone, public activity is also banned within 500 meters of Besuk Kobokan river banks, as pyroclastic surges and lahar flows may reach up to 17 km from the crater.
