Mount Semeru in East Java erupted again on Tuesday, April 9, 2024, at 10:34 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 5 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the visual eruption was not observed. The eruption was recorded on a seismograph with a maximum amplitude of 23 millimeters and a duration of 114 seconds.

According to the MAGMA Indonesia volcano 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 9, 2024, showed 9 eruption quakes with amplitudes of 10-22 millimeters and durations of 47-143 seconds.

Furthermore, there were 2 rockfall quakes with amplitudes of 6-8 mm and durations of 57-83 seconds, and 1 local tectonic quake with an amplitude of 13 millimeters, an S-P time of 4 seconds, and a duration of 20 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 kilometers from the summit (eruption center). Outside this distance, the public should not engage in activities within 500 meters of the riverbank (river edge) along Besuk Kobokan due to the potential for expansion of pyroclastic flows and lahars up to 17 kilometers from the summit.

During 2024, MAGMA Indonesia has recorded 504 volcanic eruptions/eruptions throughout Indonesia. Mount Marapi in West Sumatra had the most eruptions (161 times), while Mount Semeru erupted 160 times.
