Mount Semeru Erupts Again Today, Volcanic Ash Reaches 1,000 Meters

Mount Semeru in East Java erupted again on Wednesday, March 6, 2024, at 7:48 AM WIB. In the last week, Mount Semeru has erupted 9 times.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the observed ash column height reached 1,000 meters above the peak or 4,676 meters above sea level.

The ash column was observed to be white to gray with thick intensity towards the north. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 121 seconds.

According to the MAGMA Indonesia volcanic activity report, Mount Semeru's activity level is at Level III (Alert). Seismic observations on March 6, 2024, from 00:00 to 06:00 AM WIB showed 28 eruption quakes with amplitudes of 10-22 millimeters and durations of 85-154 seconds.

Furthermore, there were 4 emission quakes with amplitudes of 3-5 millimeters and durations of 62-66 seconds, and 4 harmonic tremors with amplitudes of 3-7 millimeters and durations of 118-512 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 edge) 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 371 volcanic eruptions/eruptions throughout Indonesia. Mount Marapi in West Sumatra had the most eruptions (124 eruptions), while Mount Semeru erupted 102 times.
