Per MAGMA Indonesia volcanic activity report, Mount Semeru activity status is set at Level III (Alert). Seismic monitoring on 15 October 2026 between 12:00-18:00 WIB recorded 26 eruption earthquakes with 10-22 mm amplitude and 60-201 second duration.
Additionally, 9 rockfall earthquakes with 2-5 mm amplitude and 27-58 second duration, plus 8 emission earthquakes with 3-8 mm amplitude and 27-61 second duration were detected.
PVMBG advises against all activities in the southeast sector along Besuk Kobokan within 13 km of the summit (eruption center). Outside this radius, communities must avoid activity within 500 meters of river banks along Besuk Kobokan, as this area is at risk of pyroclastic surge expansion and lahar flows reaching up to 17 km from the summit.
Throughout 2026, MAGMA Indonesia has recorded 5,119 volcanic eruptions across Indonesia. East Java's Mount Semeru recorded the highest activity with 1,991 eruptions.
