According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Earthquake observations on March 8, 2026 from 00:00-06:00 WIB showed 26 eruption/explosion earthquakes with amplitudes of 11-22 millimeters and durations of 60-149 seconds.

Additionally, there were 2 avalanche earthquakes with amplitudes of 4-6 mm and durations of 35-61 seconds, as well as 1 emission earthquake with an amplitude of 6 millimeters and a duration of 32 seconds.

PVMBG advises against any activities in the southeast sector along the Besuk Kobokan, within 13 kilometers of the peak (eruption center). Beyond that distance, residents should avoid 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 894 volcanic eruptions/explosions across Indonesia. Mount Semeru in East Java has the most eruptions with 456 explosions.
