Mount Semeru Erupts Again Today, Eruption Height Reaches 1,000 Meters

Mount Semeru in East Java erupted again on Sunday, May 5, 2024, at 08:50 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 16 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 1,000 meters above the peak (4,676 meters above sea level).

The ash column was observed to be white to gray with thick intensity towards the north and northeast. The eruption of Mount Semeru was still ongoing at the time of this report.

According to the MAGMA Indonesia volcano activity report, the activity level of Mount Semeru is at Level III (Alert). Observations of seismic activity on May 5, 2024, from 00:00 to 06:00 WIB showed 6 eruption quakes with amplitudes of 12-22 millimeters and durations of 75-125 seconds.

Furthermore, there was 1 harmonic tremor with an amplitude of 17 millimeters and a duration of 155 seconds, and 4 distant tectonic earthquakes with amplitudes of 6-30 millimeters, S-P intervals of 14-36 seconds, and durations of 32-123 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 conduct 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 630 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 212 eruptions.
