Mount Semeru in East Java erupted again on Wednesday, March 27, 2024, at 2:59 PM WIB. In the last week, Mount Semeru has erupted 4 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 23 millimeters and a duration of 109 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on March 27, 2024, from 6:00 AM to 12:00 PM WIB showed 19 eruption quakes with amplitudes of 10-22 millimeters and durations of 65-172 seconds.

Furthermore, there were 2 tremor quakes with an amplitude of 8 millimeters and durations of 58-62 seconds, and 2 distant tectonic quakes with amplitudes of 10-20 millimeters (s-p 13-33 seconds) and durations of 58-126 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, the public should not engage in activities within 500 meters of the riverbank (river edge) along Besuk Kobokan due to the potential for pyroclastic flow and lava flows extending up to 17 kilometers from the summit.

During 2024, MAGMA Indonesia has recorded 440 volcanic eruptions/eruptions throughout Indonesia. Mount Marapi in West Sumatra had the most eruptions (146 eruptions), while Mount Semeru erupted 135 times.
