According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is Level III (Alert). Earthquake observations on February 14, 2026 from 00:00-06:00 WIB showed 14 eruption/explosion earthquakes with amplitudes of 10-22 millimeters and durations of 81-193 seconds.
Then, 1 avalanche earthquake with an amplitude of 8 mm and duration of 161 seconds, as well as 12 emission earthquakes with amplitudes of 2-6 millimeters and durations of 61-67 seconds.
PVMBG advises against any activities in the southeast sector along the Besuk Kobokan, up to 13 kilometers from the peak (eruption center). Beyond that distance, residents are advised not to carry out activities within 500 meters of the riverbank along the Besuk Kobokan due to the potential for being affected by expanding hot clouds and lahar flows up to 17 kilometers from the peak.
Throughout 2026, MAGMA Indonesia has recorded 596 volcanic eruptions across Indonesia. Mount Semeru in East Java has the highest number of eruptions with 308 events.
