According to the MAGMA Indonesia volcano activity report, the activity level of Mount Semeru is at Level III (Alert). Earthquake observations on March 3, 2026 from 18:00 to 23:59 WIB showed 18 eruption/explosion earthquakes with amplitudes of 10-22 millimeters and earthquake durations of 50-148 seconds.

Then, 8 emission earthquakes with amplitudes of 4-8 millimeters and earthquake durations of 33-75 seconds, as well as 2 distant tectonic earthquakes with amplitudes of 6-15 millimeters, s-p 11-22 seconds and earthquake durations of 32-62 seconds.

PVMBG advises against any activities in the southeast sector along the Besuk Kobokan, within 13 kilometers of the peak (eruption center). Outside this 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 the expansion of hot clouds and lava flows up to 17 kilometers from the peak.

In 2026, MAGMA Indonesia has recorded 817 volcanic eruptions across Indonesia. Mount Semeru in East Java has the most eruptions with 417 times.
