Mount Semeru Erupts Again Today, Eruption Height Reaches 600 Meters

Mount Semeru in East Java erupted again on Wednesday, April 24, 2024, at 6:46 AM WIB. In the last week, Mount Semeru has erupted 5 times.

Citing 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 reach 600 meters above the peak or 4,276 meters above sea level.

The ash column was observed to be white to gray with thick intensity towards the north and northeast. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 95 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 00:00 to 06:00 AM WIB showed 10 eruption quakes with amplitudes of 17-21 millimeters and durations of 70-105 seconds.

Then, there was 1 puffing quake with an amplitude of 4 millimeters and a duration of 41 seconds, and 3 deep volcanic quakes with amplitudes of 14-16 millimeters, s-p 1.52-3.05 seconds, and durations of 10-14 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 boundary) along Besuk Kobokan due to the potential for the expansion of pyroclastic flows and lahars up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 577 volcanic eruptions across Indonesia. Mount Semeru in East Java has had the most eruptions, with 188.
