Mount Semeru in East Java erupted again on Friday, April 12, 2024, at 09:02 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 13 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 reach 800 meters above the peak (4,476 meters above sea level).

The ash column was observed to be white to gray with thick intensity towards the southwest. The eruption was recorded on a seismograph with a maximum amplitude of 22 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). Seismic observations on April 12, 2024, from 00:00 to 06:00 WIB showed 10 eruption quakes with amplitudes of 10-22 millimeters and durations of 48-187 seconds.

Furthermore, there were 4 emission quakes with amplitudes of 3-5 millimeters and durations of 55-57 seconds, and 5 harmonic tremors with amplitudes of 4-15 millimeters and durations of 327-1129 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, 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 peak.

During 2024, MAGMA Indonesia has recorded 520 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 168 recorded events.
