Per MAGMA Indonesia volcanic activity reports, Mount Semeru status remains at Level III (Alert). 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 (amplitude 1–4 mm, 54–66 second duration) and 2 gas emission earthquakes (amplitude 3–7 mm, 32–40 second duration) were detected.
PVMBG prohibits all activities in the southeast sector along Besuk Kobokan within 13 km of the summit. Beyond this zone, the public must also avoid activity within 500 meters of river banks along Besuk Kobokan, as pyroclastic surges and lahar flows may reach up to 17 km from the summit.
During 2026, MAGMA Indonesia has logged 3,164 volcanic eruptions nationwide. East Java's Mount Semeru recorded the highest activity with 1,397 eruptions.
