According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Earthquake observations on March 7, 2026, from 00:00 to 06:00 WIB showed 27 eruption/explosion earthquakes with amplitudes of 11-22 millimeters and durations of 65-119 seconds.

Additionally, there was 1 emission earthquake with an amplitude of 7 millimeters and a duration of 50 seconds, as well as 2 distant tectonic earthquakes with amplitudes of 10-11 millimeters, s-p times of 12-23 seconds, and durations of 41-82 seconds.

PVMBG advises against any activities in the southeast sector along the Besuk Kobokan, within 13 kilometers of the peak (eruption center). Beyond this distance, residents should avoid activities within 500 meters of the riverbanks 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 871 volcanic eruptions across Indonesia. Mount Semeru in East Java has the most eruptions with 443 events.
