Mount Semeru in East Java erupted again on Friday, April 12, 2024, at 9:08 PM WIB. In the last week, Mount Semeru has erupted 15 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the visual eruption was not observed. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 127 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on April 12, 2024, from 12:00 PM to 6:00 PM WIB showed 8 eruption quakes with amplitudes of 12-22 millimeters and durations of 54-202 seconds.

Furthermore, there were 3 tremor quakes with amplitudes of 2-8 millimeters and durations of 36-73 seconds, and 1 distant tectonic earthquake with an amplitude of 15 millimeters, S-P 73 seconds, and a duration of 170 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 kilometers from the summit (eruption center). Outside this distance, people should not engage in activities within 500 meters of the riverbank (river buffer zone) along Besuk Kobokan due to the potential for the expansion of pyroclastic flows and lava flows up to 17 kilometers from the summit.

During 2024, MAGMA Indonesia has recorded 522 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 170 eruptions.
