Mount Semeru in East Java erupted again on Sunday, March 31, 2024, at 7:37 AM WIB. In the last week, Mount Semeru has erupted 9 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the ash column height was observed to be approximately 600 meters above the peak (4,276 meters above sea level).

The ash column was observed to be white to gray with thick intensity towards the west. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 103 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Siaga) or Alert. Seismic observations on March 31, 2024, from 00:00 to 06:00 AM WIB showed 12 eruption quakes with amplitudes of 15-22 millimeters and durations of 75-115 seconds.

Furthermore, there were 3 rockfall quakes with amplitudes of 5-7 mm and durations of 48-93 seconds, and 1 emission quake with an amplitude of 4 millimeters and a duration of 31 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 kilometers from the peak (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 pyroclastic flow and lava flows extending up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 458 volcanic eruptions throughout Indonesia. Mount Marapi in West Sumatra had the most eruptions (152 times), while Mount Semeru erupted 140 times.
