Mount Semeru in East Java erupted again on Monday, April 8, 2024, at 08:31 WIB (Western Indonesian Time). This is the second eruption in the last week.

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 be approximately 700 meters above the peak (4,376 meters above sea level).

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

According to the MAGMA Indonesia volcanic activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity from 00:00 to 06:00 WIB on April 8, 2024, showed 7 eruption quakes with amplitudes of 20-22 millimeters and durations of 70-127 seconds.

Furthermore, there were 2 rockfall quakes with amplitudes of 2 mm and durations of 45-65 seconds, and 1 emission quake with an amplitude of 6 millimeters and a duration of 57 seconds.

The 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 lahar flows extending up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 497 volcanic eruptions/eruptions throughout Indonesia. Mount Marapi in West Sumatra had the most eruptions (160 times), while Mount Semeru erupted 157 times.
