Per MAGMA Indonesia volcanic activity reports, Mount Semeru activity status is set at Level III (Alert). Seismic monitoring on 29 April 2026 between 06:00–12:00 WIB detected 21 eruption earthquakes with amplitude 15–22 mm and duration 60–123 seconds.
Additionally, 1 harmonic tremor (2 mm amplitude, 162 second duration) and 1 distant tectonic earthquake (35 mm amplitude, 13 sec S-P interval, 70 second duration) were registered.
PVMBG prohibits all activities in the southeast sector along Besuk Kobokan within 13 km of the summit. Outside this zone, public activity is forbidden within 500 m of river banks along Besuk Kobokan, as this area is at risk of pyroclastic surges and lahar flows reaching up to 17 km from the crater.
During 2026, MAGMA Indonesia has logged 1,721 volcanic eruptions across Indonesia. Mount Semeru (East Java) recorded the highest count with 892 eruptions.
