Mount Semeru in East Java erupted again on Thursday, March 7, 2024, at 11:10 PM WIB. In the last week, Mount Semeru has erupted 15 times.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the ash column height was observed to reach 800 meters above the peak or 4,476 meters above sea level.

The ash column was observed to be white to gray with thick intensity towards the south. The eruption was recorded on a seismograph with a maximum amplitude of 23 millimeters and a duration of 148 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations on March 7, 2024, from 12:00 PM to 6:00 PM WIB showed 12 eruption quakes with amplitudes of 10-22 millimeters and durations of 61-115 seconds. There was also 1 distant tectonic earthquake with an amplitude of 15 millimeters, an S-P time of 14 seconds, and a duration of 30 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 lahar flows extending up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 392 volcanic eruptions/eruptions throughout Indonesia. Mount Marapi in West Sumatra had the most eruptions (135 times), while Mount Semeru erupted 108 times.
