Per MAGMA Indonesia volcanic activity reports, Mount Semeru is placed at Activity Level III (Alert). Seismic monitoring on 6 August 2026 between 12:00-18:00 WIB recorded 19 eruption earthquakes with 10-21 mm amplitude and 59-109 second duration.
Additionally, 6 rockfall earthquakes (2-3 mm amplitude, 38-54 seconds duration) and 8 gas emission earthquakes (3-5 mm amplitude, 30-54 seconds duration) were detected.
PVMBG prohibits all activities in the southeast sector along Besuk Kobokan within 13 km from the summit. Outside this zone, public activity is also forbidden within 500 meters from river banks along Besuk Kobokan, due to risk of pyroclastic flow expansion and lahar hazards reaching up to 17 km from the crater.
Throughout 2026, MAGMA Indonesia has logged 3,768 volcanic eruptions across Indonesia. East Java's Mount Semeru recorded the highest activity with 1,546 eruptions.
