As per MAGMA Indonesia volcanic activity reports, Mount Semeru is currently set at Activity Level III (Alert Status). Seismic monitoring between 12:00 - 18:00 WIB on 27 May 2026 recorded 12 eruption earthquakes with 15-22 mm amplitude, lasting 93 to 175 seconds each.
Additionally, 2 rockfall earthquakes (10-12 mm amplitude, 101-175 sec duration) and 2 gas emission tremors (4-8 mm amplitude, 35-52 sec duration) were detected.
PVMBG prohibits all activities in the southeast sector along Besuk Kobokan within 13 km of the summit. Outside this zone, no activity is allowed within 500 meters of Besuk Kobokan river banks, as pyroclastic surges and lahar flows may reach up to 17 km from the crater.
