Per MAGMA Indonesia volcanic activity reports, Mount Semeru is set at Activity Level III (Alert Status). Seismic monitoring on 15 June 2026 between 18:00 - 23:59 WIB recorded 11 eruption earthquakes with amplitude 10-22 mm and duration 90-152 seconds.
Additionally, 5 emission earthquakes (amplitude 3-6 mm, 60-111 sec duration) and 1 distant tectonic earthquake (30 mm amplitude, 31 sec S-P interval, 138 sec total duration) were detected.
PVMBG prohibits all activities in the southeast sector along Besuk Kobokan river basin within 13 km from the summit. Outside this zone, residents must also avoid activity within 500 meters of the Besuk Kobokan river banks, as pyroclastic surges and lahar flows may impact areas up to 17 km from the peak.
During 2026, MAGMA Indonesia has recorded 2653 volcanic eruptions nationwide. Mount Semeru (East Java) recorded the highest activity with 1253 eruption events.
