Per MAGMA Indonesia volcanic activity reports, Mount Semeru is currently set at Activity Level III (Alert). Seismic monitoring between 06:00-12:00 WIB on 18 May 2026 recorded 14 eruption earthquakes with 15-22 mm amplitude and 92-175 second duration.
Additionally, 4 degassing earthquakes (2-8 mm amplitude, 31-67 second duration) and 2 distant tectonic earthquakes (15-35 mm amplitude, 14-16 sec S-P interval, 37-76 second duration) were detected.
PVMBG prohibits all activities along the Besuk Kobokan river valley within 13 km of the summit on the southeast flank. Outside this zone, public activities are forbidden within 500 meters of river banks along Besuk Kobokan, as pyroclastic surges and lahar flows may reach up to 17 km from the summit.
As of this event, MAGMA Indonesia has logged 2,038 volcanic eruptions across Indonesia in 2026. Mount Semeru alone has accounted for 1,031 of these eruptions.
