Mount Semeru Erupts Again Tonight (Wednesday, April 10, 2024)

Mount Semeru in East Java erupted again on Wednesday, April 10, 2024, at 7:52 PM WIB. In the last week, Mount Semeru has erupted 7 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the height of the ash column was observed to be approximately 500 meters above the peak or 4,176 meters above sea level.

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

According to the MAGMA Indonesia volcanic activity report, the activity level of Mount Semeru is at Level III (Alert). Seismic observations on April 10, 2024, from 12:00 PM to 6:00 PM WIB showed 7 eruption quakes with amplitudes of 10-22 millimeters and durations of 66-118 seconds.

Then, there was 1 harmonic tremor with an amplitude of 6 millimeters and a duration of 232 seconds, and 2 distant tectonic earthquakes with amplitudes of 12-20 millimeters, S-P 14.5-16.3 seconds, and durations of 45-63 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 506 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has had the most eruptions, with 162 eruptions.
