According to MAGMA Indonesia volcanic activity reports, Mount Semeru remains at Alert Level III (Standby). Seismic monitoring between 00:00 - 06:00 WIB on 14 July 2026 recorded 16 eruption earthquakes with amplitude 13-22 mm and duration 64-143 seconds.
Additionally, 3 rockfall earthquakes (1-4 mm amplitude, 54-66 sec duration) and 2 emission tremor events (3-7 mm amplitude, 32-40 sec duration) were detected.
PVMBG prohibits all activities in the southeast sector along the Besuk Kobokan within 13 km of the summit. Beyond this zone, residents must avoid staying within 500 meters of river banks along Besuk Kobokan, as pyroclastic surges and lahars may reach up to 17 km from the peak.
For the year 2026, MAGMA Indonesia has logged a total of 3,171 volcanic eruptions nationwide. Mount Semeru (East Java) recorded the highest activity with 1,400 eruptions.
