According to the MAGMA Indonesia volcanic activity report, the activity level of Mount Semeru is at Level III (Alert). Earthquake observations on April 25, 2026 from 18:00 to 23:59 WIB showed 15 eruption/explosion earthquakes with amplitudes of 10-22 millimeters and durations of 69-159 seconds.
Then, 1 collapse earthquake with an amplitude of 4 mm and duration of 154 seconds, as well as 5 emission earthquakes with amplitudes of 3-7 millimeters and durations of 47-66 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 should not 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 lava flows up to 17 kilometers from the peak.
Throughout 2026, MAGMA Indonesia has recorded 1,654 volcanic eruptions across Indonesia. Mount Semeru in East Java has the most eruptions with 858 events.
