Warning! Mount Semeru Erupts Again This Afternoon (Wednesday, April 24, 2024)

Mount Semeru in East Java erupted again on Wednesday, April 24, 2024, at 4:37 PM WIB. In the last week, Mount Semeru has erupted 6 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 (4,476 meters above sea level).

The ash column was observed to be white to gray with thick intensity towards the northwest. The eruption was recorded on a seismograph with a maximum amplitude of 23 millimeters and a duration of 80 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on April 24, 2024, from 6:00 AM to 12:00 PM WIB showed 6 eruption quakes with amplitudes of 20-22 millimeters and durations of 70-115 seconds.

Then, there was 1 harmonic tremor with an amplitude of 8 millimeters and a duration of 166 seconds, and 2 distant tectonic earthquakes with amplitudes of 24-32 millimeters, s-p 13-18 seconds, and durations of 41-82 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 580 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has had the most eruptions, with 189 eruptions.
