According to the MAGMA Indonesia volcano activity report, the activity level of Mount Semeru is at Level III (Alert). Earthquake observations on February 15, 2026 from 06:00-12:00 WIB showed 25 eruption/explosion earthquakes with amplitudes of 8-23 millimeters and earthquake durations of 67-146 seconds.

Then, 1 avalanche earthquake with an amplitude of 3 mm and duration of 45 seconds, as well as 2 emission earthquakes with amplitudes of 4-6 millimeters and durations of 42-50 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 not 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.

Throughout 2026, MAGMA Indonesia has recorded 608 volcanic eruptions across Indonesia. Mount Semeru in East Java has the most eruptions with 315 times.
